Phase I will identify the capabilities needed to develop a viable system utilizing an object-oriented database (OODB) to support the development of a central repository for defining, classifying, and organizing terrain features.This capability will provide geographic information system (GIS) users with a common set of terrain features and characterizations with which to build their applications. The project will identify key objects and will determine how they characterize and manipulate, how and what information should flow between objects, and how the objects should be abstracted into classes. The effort will produce a prototype that integrates the resulting geographical object-oriented database with a GIS. The prototype will build on new object-oriented data structures and permit evaluation of the feasibility of the geographical object-oriented database concept and its suitability for the problem domain. The prototype will also serve as a major tool in the establishment of system-functional and computer-software-module integration requirements.This project should provide GIS users with a common set of terrain features and characterizations with which to build their applications.object-oriented, database, OODB, OOP, GIS, terrainSTATUS: Phase I Only
