An integrated knowledge-based system for managing spatiotemporal ecological simulations

The Knowledge-Based Land Information Manager and Simulator (KBLIMS) is a system for managing spatiotemporal simulations of ecological processes organized around a watershed-based model of terrain. It demonstrates that an object-oriented spatial database for watersheds can be easily organized as a graph and exploited as such for building a query system. KBLIMS includes modules for the extraction of a watershed representation directly from grid digital elevation models and an object-based information system allowing the selection, browsing, navigation among, and query of watershed objects using a graphical user interface. -from Authors
