Item Details
SUMMARY

InVEST Scenario Generator is a desktop application that provides a relatively easy approach for making scenario storylines spatially explicit when data and resources are limited. It is appropriate for use when the aim of scenario development is to represent stakeholder visions, preferences or key uncertainties about the future rather than to project trends or predict the future. Also, with user-defined growth goal, the tool can add new land cover type to scenario maps.

Check the “tools for process” for potential tools and approaches to collect input for InVEST Scenario Generator. You may also check the Scenario Hub Workspace that helps you compile input data for SG. 

INPUT - REQUIRED [Spatial] baseline LULC raster [Non-spatial] Amount/percentage of growth
INPUT - OPTIONAL [Spatial] physical suitability map or spatial features that affecting the suitability, constraints [Non-spatial] Transition likelihood matrix, transition priority,
OUTPUT LULC raster for defined scenario, with statistics summarizing the change
HOW ARE SCENARIOS DECIDED?

Growth: user / stakeholder / expert estimates 

Allocation: calculated based on user-defined spatial rules and transition likelihood matrix
