URBAN AND REGIONAL PLANNING
(Version 12-13-99)

Zorica Nedovic

SCOPE AND DESCRIPTION OF THE APPLICATION CHALLENGE

Planning is a future-oriented activity that links "scientific and technical knowledge to actions in the public domain" (Friedmann 1987, page 38). It happens through a public discourse between all groups and individuals interested in and/or affected by urban development and management activities pursued by the public or private sector. Urban and regional planning agencies are rich and dynamic arenas where many societal problems and solutions are explored and addressed in a direct and tangible way. Urban growth; unemployment and economic revitalization; transportation; environmental degradation and protection; neighborhood decline and redevelopment; historic preservation; provision of open space, parks, and recreational facilities; and conservation of land and natural resources are examples of such problems and solutions. Planning-related decisions are made daily through a complex, often politically charged process involving plurality of interests. Moreover, the implementation of those decisions makes a long-term imprint on the urban structure, functionality, and quality of life in urban environments. While most of urban and regional planning happens at the local level, planning activities are often influenced by national and state policies and legislation.

Planners have always sought tools to enhance their analytical, problem-solving, and decision-making capability (Mandelbaum 1996). From the late 1950s planners started to develop and use computerized models, planning information systems and decision support systems to improve performance (Brail 1987; Klosterman 1990). Adoption of geographic information systems (GIS) is a more recent manifestation of the same effort to incorporate new tools and technologies. Planning departments have been on the forefront of GIS use among local government agencies (French and Wiggins 1990; Juhl 1993; French and Skiles 1996; Warnecke et al. 1998). The planners’ interest in GIS derives from the spatial nature of urban phenomena and from the inter-disciplinary nature of urban planning.

Ultimately, the GIScience as applied in the field of urban and regional planning should contribute to the following goals of urban and regional planning practice:

Planners can apply geographic information technologies in all aspects of the planning process, including: data collection and storage, data analysis and presentation, plan and/or policy making, communication with the public and decision makers, and plan and/or policy implementation and administration. GIS technology is most commonly used for comprehensive planning, zoning, land use inventories, site suitability assessments, and socio-demographic analysis, and generally for mapping purposes (Budic 1993, 1994; Warnecke et al. 1998). Planners use GIS primarily for mapping activities. The value of maps in understanding and communicating planning issues is well recognized and appreciated. The more sophisticated analytical applications, which contribute to other aspects of the planning process, are less developed.

Past research confirms that the GI-based tools developed by vendors and/or academics are for various reasons underutilized and unsuitable for planning (Harris 1989; Harris and Batty 1993; Holmberg 1994; Klosterman 1997). In their study of parcel-based GIS for land supply and capacity monitoring, Vernez-Moudon and Hubner (forthcoming) attribute this underutilization of GIS technology to the inadequate capacity and structure of planning institutions, which remain unsuited to the new forms and processes required for effective utilization of planning and decision support systems. This same problem has persisted from the early attempts at computerization of land supply monitoring in the 1980s (Godschalk et al 1985; Bollens and Godschalk 1987). The additional reasons for underutilization of GIS in planning include, but are not limited to the complexity of technology, lack of trained staff, scarce organizational resources, and incompatibility of the mostly generic GI products with the tasks and functions performed by urban and regional planners. The ability to incorporate urban models and to more directly support the decision and policy making processes are two main defficiencies of the current spatial technologies and tools.

GI Science would contribute to better urban planning if it addressed the following challenges:

MAJOR GI SCIENCE CONTRIBUTIONS AND SIGNIFICANCE

Planning theory is based on two types of rationality that are relevant for understanding the role of geographic information science and technology in urban and regional planning. These are instrumental and communicative rationality. Instrumental (functional) rationality is based on a positivist ideal, which puts information gathering and scientific analysis at the core of planning. It assumes a direct relationship between the information available and quality of decisions based on this information. Communicative (substantive or procedural) rationality focuses on open and inclusive planning process, public participation, dialogue, consensus building, and conflict resolution (Innes 1996; Godschalk et al. 1994). While the two theoretical stances are often viewed as competing (Mannheim 1940; Sager 1990; Yifachel 1999), the role of information is relevant to both of them (and not restricted to instrumental rationality as the more traditional view would hold). Participants in the planning process rely on many types of "information," including both the formal analytic reports and quantitative measures and the understandings and meanings attached to planning issues and activities (Innes 1998). Indeed, geographic information science and technology have started to contribute to the planning practice, and in some areas the developments transcend the "communicate versus calculate" dichotomy.

Following is a review of the main areas of geographic information research that carry the potential of being the most useful for urban and regional planning practice. These areas are:

  1. GIS database developments for planning-related analysis;
  2. Integration of GI technologies with urban models;
  3. Building of planning support systems;
  4. Facilitating discourse and participation in the planning process; and
  5. Evaluation of planning practice and technological impact.

GIS database developments for planning-related analysis

Data collection takes up a considerable proportion of planners’ resources. In fact, the effort put into database development is sometimes so immense that leaves little time for analysis and for creative activities in designing plans and/or policies (Arbeit 1993). GIS database development must be based on clear understanding of planning problems, process, and context (le Clercq 1990). Furthermore, since planning databases are usually derived by compiling data from multiple sources and of varying quality and scales, the rules of interoperability and integration are necessary to apply (Devogele et al. 1998). Integration of readily available datasets is one way to reduce database development and maintenance time. For example, remote sensing data acquired via satellites or airborne cameras (Mesev 1997; Tellez and Servigne 1997), have proved very useful, particularly in mapping land use change (Lo and Shipman 1990; Logsdon et al.1996), population density (Sutton 1997), and human activities and their outcomes (Schweik and Green 1999). Finally, incorporation of data at several points in time is often useful, but requires system designers to be familiar with building dynamic GIS (Asproth et al. 1995).

In the positivistic vain, GIS databases are most frequently used for performing planning-related analysis and scientific inquires (Wellar et al. 1994). Webster (1993, 1994) matches the scientific input required to the various stages of the planning process:

  1. problem identification requires description and prediction;
  2. goal setting, plan generation, evaluation of alternatives, and choice of solution requires prescription;
  3. implementation requires description, prediction, and prescription; and finally
  4. monitoring requires description and prediction.

The author claims a limited value of GIS technology for predictive analysis, which is crucial for understanding the consequences resulting from future planning actions. While the GI-based tools have proved useful for understanding physical and environmental processes, the socio-economic dynamics are still hard to model and/or simulate. To address this shortcoming, extensions toward enabling statistical analysis within the GIS environment have been attempted (Zhang and Griffith 1997; Luc Anselin, SpaceStat Web Site).

Integration of GI technologies with urban models

To enable prediction of urban phenomena and processes, GIS software must allow for modeling procedures to run within its environment. This is, incidentally, one of the most frequently cited deficiencies of GIS (Harris and Batty 1993). Predictive modeling is usually performed outside GIS and loosely coupled to the system via programming procedures. Embedding of urban models within GIS has been attempted in advanced research projects (Batty and Xie 1994), but has not become part of commercial GIS software. Landis’ (1994, 1995) California Urban Futures Model, Landis et al. (1998) California Urban and Biodiversity Analysis, and Klosterman’s (1999) "What if?" are probably the three most comprehensive attempts to date in simulating land use scenarios resulting from given demographic and economic trends, environmental constraints, and urban development policies. The progress in modeling land use change in particular is impressive (Matheny et al. 1999), but yet to gain usability and acceptance in planning agencies at various levels of government.

Building of planning support systems

Planning support systems (PSS) aid the planning process via integrated developments usually based on multiple technologies and common interface. PSS are expected to facilitate data management, analysis, problem solving, design, decision making, and communication activities. Hopkins (1999), for instance, conceives of PSS to provide "views and tools for sketch planning, model building, scenario building, evaluation, lineage tracking, and plan-based action" (p. 333). He finds, however, that GIS mapping concepts are insufficient for building PSS. Despite the limited value, GIS have become a useful component and an integral part of PSS, which tend to incorporate one or more of the following features: modeling procedures (Harris 1999; Kammeier 1999), expert systems (Edamura and Tsuchida 1999; Shi and Yeh 1999), databases, decision trees, computer aided design or CAD (Alley 1993; Schuur 1994; Ranzinger and Gleixner 1997), hypertext (George 1997), mapping (Singh 1999), user interfaces for public participation (Shiffer 1992), virtual reality, and World Wide Web (Doyle et al. 1998; Heikkila 1998).

Planning support systems have evolved along with planning practice as (Klosterman 1997). : a) applied science in 1960s; b) politics in the 1970s; and communication in the 1980s. Corresponding to this evolution is the information science concern with data, information, and knowledge, respectively. Intelligence and collective design are the modus operandi of urban planning. In line of increasingly recognized collective nature of planning analysis, design, communication, and decision-making, the 1990s have witnessed development of collaborative planning systems, planning groupware, and co-operative work systems (Jones 1998). Laurini (1998) defines groupware as a "set of computer- and network-based technologies [that] allows several users, located at different sites and using different work-practices, to work together towards the same goal" (p. 315). Referring to a group planning situation, Shiffer (1992) discusses group cognition, access to media, and access to computerized analysis tools as components of a holistic planning process. He built several prototype systems to integrate and test these concepts in the planning contex.

Development of group support systems technology (Coleman and Khanna 1995), including group decision support systems (DeSanctis and Gallupe 1987, Hwang and Lin 1987), as well as theoretical and empirical studies of its use (Jessup and Valacich 1993, Chun and Park 1998), have been carried out in the management and decision sciences for over ten years. More recently, information technologies such as geographic information systems (GIS) (Godschalk et al. 1992, Faber et al. 1994, 1995, 1996), their offspring spatial decision support systems (SDSS) (Armstrong 1993, Densham 1991, Heywood, Oliver, Tomlinson 1995, Jankowski et al. 1997, Nyerges et. al. 1998b, Reitsma 1996), and spatial understanding (and decision) support systems (SUSS/SUDSS) (Couclelis and Monmonier 1995, Jankowski and Stasik 1997) are being suggested as information technology aids to facilitate geographical problem understanding and decision making for groups, including groups embroiled in locational conflict. Clearly, research concerning collaborative decision making for geographically-oriented public policy problems continues to gain momentum (Couclelis and Monmonier 1995, Densham, Armstrong and Kemp 1995, Faber et al. 1994, 1995, 1996, Godschalk et al. 1992, Golay and Nyerges 1995, Jankowski et al. 1997, Nyerges and Jankowski 1997, Nyerges et al. 1998a, Nyerges et al. 1998b, Reitsma 1996, Reitsma et al. 1996, Shiffer 1992).

Facilitating discourse and participation in the planning process

Similar to other technologies, GIS is socially constructed via negotiations between various social groups (Harvey and Chrisman 1998). In the case of planning, those groups include professional staff, decision-makers, developers, special interest groups, citizens, and other stakeholders. GIS technology promises to improve public access to information and facilitate public participation in the planning and policy making process. Contrary to the expectation that GIS will enhance democracy and empower disadvantaged groups, Clark (1998) warns about the creation of GIS technocratic elite. In her study of Virginia planning agencies Nedovic-Budic (1998) finds little evidence about improvements in public access to data. Sieber (1998) reports the difficulties experienced by non-profit organizations in obtaining GIS data. Meanwhile, there is an increasing trend toward empowering communities to plan through provision of integrated GIS software and planning databases. HUD’s new Community 2020 CD ROM package, made available to local governments on a national basis, bundles Caliper’s Maptitude with an extensive database of geographic, demographic, and programmatic information. Seattle’s Neighborhood Data Viewer, provided to its neighborhood planning groups, includes ArcView and a comprehensive database of maps on land use, crime, and other planning information. Several authors offer examples of the positive effect of GIS and other technologies on community participation in the planning process (Sawicki and Craig 1996; Craig 1998; Sarjakoski 1998; Schon et al. 1999). New developments which strive to include in GI-based systems the subjective information on citizens’ perceptions, views, and ideas, promise to enhance even further the potential of GI technology and tools to aid public participation in the planning process (Al-Khodmany 1999, Talen 1999).

Evaluation of planning practice and technological impact

Evaluation research is pursued in two venues: one is GIS-aided evaluation of the quality of urban communities and of planning practice; the other is evaluation of GIS impact on planning process, practice, and outcomes. With respect to planning practice, Talen (1998) applies GIS to examine the equity in distribution of pubic services to various segments of the community, and to search for areas that have not received adequate planning attention and have not been allocated their fair share of public resources. In an earlier study, Talen (1996) uses GIS to assess achievement of open space goals by comparing the planned and implemented projects. Knaap et al. (1998) have used GIS in their evaluation of the relevance and outcomes of planning. They ask if planning matters, and to answer this question they model the land development process as interaction between local government policies and land market participants to measure the effect of planning as a change in social welfare. Finally, the Urban Institute has initiated a project to explore a feasibility of creating national system of indicators to be sued for evaluating the quality of life at the neighborhood level (Sawicki and Flynn 1996).

The other research venue has to do with finding out if the employment of GI technologies and tools have made any difference in planning practice. Planners have always been on the forefront of GIS diffusion, but the benefits to them are not yet well documented. To understand the impact of GIS and apply that information in designing systems that will suit planning practice, Nedovic-Budic (1998, 1999) reviews the evaluation frameworks, methods, and empirical studies. The evaluation dimensions include: system quality, information quality, information use, user satisfaction, individual impact, organizational performance (i.e., efficiency and effectiveness), and societal impact. The author finds that information processing is still perceived as the main GIS benefit, while the enhancement in decision-making and empowerment is yet to be achieved. Montagu (1999) examines the fit between GIS technology and the natural resource planning process in the context of Papua New Guinea’s state government. He finds "little impact on the planned outcomes of environmental management across the country" and argues that the "domination of the prevailing political economy of environmental management in the planning process" is the reason for inadequate utilization of well-designed and custom-developed GIS. Obviously, the experiences and insights into building successful GIS in planning organizations at various levels, different mandates, and diverse settings, will provide useful information for many current and prospective users.

GIS-based research in planning spans all five contribution areas (listed above) and a variety of planning subfields, including urban growth management, land use planning, zoning, housing, community and economic development, transportation planning, environmental issues, provision of community parks and open space, and supply of public utilities and amenities. Examples of those applications are listed in the bibliography.

UCGIS RESEARCH PRIORITIES

  1. Spatial Data Acquisition and Integration
  2. Distributed Computing
  3. Extensions to Geographic Representations
  4. Cognition of Geographic Information
  5. Interoperability of Geographic Information
  6. Scale
  7. Spatial Analysis in a GIS Environment
  8. The Future of Spatial Information Infrastructure
  9. Uncertainty in Geographic Data and GIS-Based Analyses
  10. GIS and Society

UCGIS research priorities are all applicable to the field of urban and regional planning. Data collection and integration are the most time consuming planning activities and GIS is a prominent tool to aid in data-related activities. The data-related understanding between planners and engineers is probably the one that needs improvement the most. Two way exchange, with planners appreciating and taking advantage of the engineering precision and accuracy, and with engineers’ ability to utilize more uncertain and generalized planning data, is still a challenge to overcome. If the traditional planners’ connectivity to engineering and many other public and private organizations is to be realized by computer-based networking, distributed computing, interoperability, and scale issues are essential for enabling exchange of data between many specialized local agencies. Planners need to understand the quality of data and analyses they rely upon for plan and policy-making. Better analytical capabilities embedded in GIS software would also be useful extension of existing tools.

Advancements in the NSDI and Web tools hold the potential to improve the public access to planning information and the democratic and participatory requirements in the planning process. Understanding the cognitive aspects of GI-based tools will enhance planners’ effectiveness in using these tools to communicate with decision-makers and the public. This understanding will also lead to development of tools that match the cognitive structures of various groups involved in the planning process. Finally, having the society as a reference for evaluating the impact of technology is compatible with public nature of most urban and regional planning activities, which strive for increasing community welfare and quality of life.

Urban and regional planning applications will certainly benefit from the research in the priority areas listed above. These priorities, however, promise to extend on the generic aspects of GI tools, but do not address the specific needs of planning practice. The most critical areas that are focused on urban and regional planning needs include:

Development of planning support systems include integration of GI with other technologies (hypertext, groupware, audio/visuals, multimedia, models, simulations, expert systems, etc.). Although the strides have been made in that direction (as evidenced in the most recent issue of Environment and Planning B - 1999, 26/3), many challenges are still ahead. Current developments of customized GI and other tools only partially respond to analytical, design, administrative, communicative, and decision-making support needed. Integration of those modules into a functional planning support system and their customization to various planning institutions is yet to be acheived.

Similarly, most of the collaborative decision-making support systems research is about GIS development rather than about GIS use, without a strong theoretical link between the two. Consequently, broadening and deepening the conceptual underpinnings about GIS-supported collaborative decision making is a major research goal. To advance the GI science and to be useful in urban and regional planning practice, this broadening has to take the perspective of geographic information use. Evaluation of impact of GI technologies and tools is probably the most direct way of providing a link between the science and planning practice. Theoretically founded and systematic evaluation provides knowledge that can inform GI diffusion, and can be applied in strategies for achieving effective implementation of GI technologies and tools.

Once the planning tools are developed, they have to be effectively introduced into planning organizational settings. Technology transfer and incorporation of technology in the planning process is, therefore, a challenge related to building of PSS. This process usually implies a major organizational change and re-structuring to create new organizational forms, processes, procedures, information flows, and responsibilities. The organizational change implies mutual adjustment between the technology and the organization (Nedovic-Budic 1997). While the knowledge base about GIS implementation process has started to consolidate during the past decade (Innes and Simpson 1993; Budic and Godschalk 1994; Campbell and Masser 1995; Huxhold and Levinsohn 1995; Nedovic-Budic and Godschalk 1996; Tulloch et al. 1996; Brown 1997; Azad 1998), the lessons learned are generic and not directly applicable to the planning context. Better understanding of planning organizational contexts and processes is crucial for effective embedding of planning support systems.

Understanding the relationship between planning theory and methods and GI technology is crucial for building and implementing tools that are suitable to planning practice. Esnard and MacDougall (1997) maintain that there is a common ground for integrating planning theory and GIS in data creation, analysis, and presentation. They suggest this integration as part of an educational experience. Guhathakurta (1999) also finds that urban modeling and decision support tools can be developed to serve practice and to link to its theoretical underpinnings. The author refers to a new form of rationality, which encompasses both positivist and interpretative epistemiology, promises to provide framework for development of planning technologies and tools.

In addition to the rational theory, social theory and postmodernism form vital cornerstones to planning theory. These theories provide a critique of the use of technology in the planning process and the rejection of a single narrative discourse usually pursued via the information technology (despite the technological capability to handle multiple narratives and views). Both theories relate to economic restructuring and globalization -- topics well-covered in planning and geography, and, certainly assisted by spatial technologies. Without establishing these linkages between planning theory and practice, the technological developments would operate in a vacuum and end up being driven by immediate short-term concerns rather then overarching mission and purpose of planning action.

Finally, visualization of existing urban-related processes and phenomena and simulation of outcomes of proposed plans and policies is in the core of planning practice. Further developments in 3D modeling, virtual reality, incorporation of images, easy graphical manipulation of various urban components, movement through space, changing perspectives, link with planning and policy documentation and descriptive statements, annotation tools for dialogue and commentary, will all enhance the communication capacity of urban planners. As in the case of all applicable technologies, to make the visualization tools useful for planning practice, their customization and integration into the planning process will be a necessary aspect of the development.

UCGIS EDUCATION PRIORITIES

http://www.ncgia.ucsb.edu/other/ucgis/ed_priorities/geoinfosystems.html

  1. Emerging Technologies for Delivering GIScience Education
  2. Supporting Infrastructure
  3. Access and Equity
  4. Alternative Designs for Curriculum Content & Evaluation
  5. Professional GIS Education Programs
  6. Research-based Graduate GIS Education
  7. Learning with GIS
  8. Accreditation and Certification

The UCGIS education priorities listed above are all applicable to the field of urban and regional planning. GIS is described as "another quiet revolution" in the planning practice, and GIS courses have been introduced as an important component in the undergraduate and graduate planning curricula. GIS-related capabilities, techniques, and methods contribute to several skill areas of professional planners, including: analytical/research, communication, and data processing (Godschalk and McMahon 1992; Friedmann and Kuester 1994; Kaufman and Simons 1995). Infrastructure for teaching is crucial, but difficult to secure and make fully accessible in planning schools and departments. The demand for continuing education and training of planning professionals in emerging geographic information technologies also has to be met. The educational materials, however, for both regular programs and continuing education need to be tailored to the disciplinary framework of urban and regional planning by providing examples from planning practice and using methods that are common to planners.

As suggested in the list of educational priorities, securing exposure to GIS through research is a desired educational practice among planning programs. Finally, with regard to certification, the American Institute of Certified Planners (AICP) and Amrican Planning Association (APA), which have both began to recognize GIS training as one of the professional requirements, are for now unlikely to pursue any GIS-related certification, although the future may be different. However, other organizations, like the Urban and Regional Information Systems Association (URISA), have started to seriously discuss the issues of professional education and certification (http://www.urisa.org/certific.htm). The area where professional planning associations may assume a stronger role is in the program accreditation process. For example, Planning Accreditation Board (PAB) may start to look close into the programs’ provision for education in GI-based computerized technologies and tools.

Closely related to the professional accreditation and certification is the question of ethics. This question is subsumed under the UCGIS research priority GIS and Society, which states that it is important to "lessen the likelihood that geographic information technologies will be misused, or their products misinterpreted, or inappropriate decisions be made based on their products." Practicing ethical behavior and possibly developing and adhering to a professional code of ethics, is, however, in the realm of education and certification.

Esnard (1998) alerts us that the codes of ethics and ethics in general are so critical and need to be a high priority for educators who prepare the next generation of professional planners. The author asks how do we seriously think of constructing guidelines that can serve as simple common language of ethical behavior -- guidelines that are easy to remember and build upon. Should the multi-disciplinary GIS community have a common code for all GIS users and if so, what happens to our own professional codes, in case of planners -- the American Institute of Certified Planners’ (AICP) and the American Planning Association’ (APA) AICP/APA Ethical Principles in Planning. Esnard finds the current provisions addressing data analysis and information to be outdated and sometimes contradictory. She calls for both studying the questionable uses of information technology to understand their ethical and legal implications and impacts, and using the examples of misuse as the source of education. Defining a framework that would help GIS practitioners delineate the behavioral boundaries and make judgements about their responsibilities and actions is of utmost priority.

In summary, the following are educational priorities that would respond more closely to the needs of urban and regional planning:

POLICY IMPLICATIONS

The policies that would help advance the application of GI technologies and tools in urban and regional planning practice are in the areas of standardization, database development, access to data, tool building and integration, technology transfer, and legal framework. Each of the areas is briefly discussed below.

Support for development and maintenance of local databases

One of the most time consuming and difficult task performed by planners is data collection in support of particular project and/or agency function. In addition to collecting primary data, planners draw on numerous secondary data sources, including other agencies and government censuses, to acquire data and integrate them into a useful database. External support in developing local databases, for example on properties, streets, utilities, and detailed neighborhood characteristics, would be of great value to local planners. This support could come in form of technical assistance, staffing, and/or financing options, and would not necessarily have to be managed within planning agencies, as long as the planners’ have access to other databases developed by public funds.

Standardization

While integrating data from a variety of sources, planners deal with issues of data format and quality on daily basis. Standardization of data, formats, and metadata would help alleviate some of the difficulties in physically integrating the data, and would promote common terminology and contents in describing data. As in the case of database development and maintenance, the focus should be at the local level, where it is most difficult to establish and adhere to common features that would be acceptable to multitude of local dadta providers and users. Awareness about the existing standards and standardization efforts is the first step in preparing the local GIS communities to consider and accept standardization of GI technologies and products.

Access to data

Similar to standardization, access has its technical and non-technical aspect. Technically, the tools for accessing data of various formats and proprietary codes are yet to be developed. The non-technical issue has to do with legal right to access government generated data and records, as well as with organizational motivation and willingness to provide open access to their data holdings. The easier it is to import and convert various geographic and attribute data formats, and the more open the database owners are toward free access to their databases, the more firm will be the foundation for building the National Spatial Data Infrastructure.

Tool building and integration

Planning support systems are applied in a unique organizational and social environment and under specific circumstances. Most of the planning support systems would be employed in a local government settings where the nature, intensity, and impact of urban development and re-development are contested on daily bases between various public and private stakeholders and decision makers. While generic research in decision support systems provides relevant frameworks, concepts, and tools to be applied in planning practice, only the research in the planning specific context would secure achievements that are useful to planning practice and would hopefully enhance it. Therefore, funding by the major funding agencies in the US and abroad should be encouraged to explicitly address the needs of local planning. This research is very broad in scope to include tool integration, decision systems, simulation, visualizaiton, and modeling in planning specific settings.

Education and technology transfer

Education is one way of preparing people for future use of GI technologies and tools. Encouraging such GI-focused educational programs throughout the college experience and later during professional continuing education, is an important step in raising awareness about the existing technological potential and in providing skills for operating and developing GI technologies and tools. To aid the actual diffusion of GI technologies and tools, the inventors of new planning support tools should be required to disseminate their products in the real organizational/user settings. While commercial GI products generally find their way quickly to the market, the developments from academia which are often more sophisticated and potentially more useful, tend to remain buried in research reports and articles and seldom reach the wide range of professional and voluntary groups, which could benefit from those developments.

Legal framework

In addition to already mentioned issue of data access, there are a number of other legal issues that pervade the use of GI technologies and data in the practice of urban and regional planning. These other issues include: liability, copyright, cost recovery, and public access. While the general framework on all of the issues with regard to government and private sector data and practices has been established, the applicability to digital geographic information is debated. The legal environment in which GI is produced and used is highly uncertain and often discouraging to creative GI-related activities and developments. The current legal structures are subjected to numerous interpretations and new rules and procedures established locally and by state. A well articulated legal framework would help private and public sector organizations and individuals define their roles and responsibilities with respect to spatial data and would help stabilize their practices and relationships.
