Envision is a model framework to simulate alternative scenarios of future land use and landscape production pattern. The change of the land use is simulated by agent-based model, with policies and other autonomous landscape process considered. It also takes plug-in evaluative models to update metrics used for agent decisions.
Note that the analysis in Envision is vector-based, therefore the LULC map should be polygon map.
|INPUT - REQUIRED||[Spatial] IDU ( Independent Decision Unit map) & associate attributes [Non-spatial] Agent decision rules|
|INPUT - OPTIONAL||[Spatial] landscape component polygon maps, location-based policies [Non-spatial] Attributed-based policies [Models] plug-in autonomous landscape change models, plug-in evaluative models|
|OUTPUT||Change of IDU attributes (use type) over time|
|HOW ARE SCENARIOS DECIDED?||
Scenarios in Envision are driven by initial status, decisions made by modeled actors, spatial policies, and landscape processes.
|FORM||Standalone desktop application (32-bit & 64-bit compatible)|
|CAN I ALTER THE MODEL?||Yes, it provides a Software Development Toolkit for developing plug-in evaluative models and autonomous processes|
|SCALE/RESOLUTION||Local to regional|
|REQUIRE GIS TOOL TO RUN THE MODEL?||No|
