A New Object-Oriented Data Model for Oceans, Coasts, Seas, and Lakes
2004 Association of American Geographers Centennial Meeting
SPECIAL SESSION: GIS in Marine and Coastal Environments
The conceptual framework and design of the model will be discussed, and how it seeks to take fuller advantage of the most advanced manipulation and analysis capabilities of ArcGIS, particularly its support of more complex rules that can be built into its geodatabases, and of objects with not only attributes, but behavior. A further goal is the support of existing data standards, so as to help simplify the integration of data at various jurisdictional levels. For users, the model provides a basic template for implementing GIS projects (e.g., inputting, formatting, geoprocessing, and sharing data); for developers , it provides a basic framework for writing program code and maintaining applications. The model also considers how marine and coastal data might be more effectively integrated in 3-D space and time, with "placeholders" meant to represent the fluidity of ocean data and processes.
