When translating policy to planning, it is often important to take guidelines (or “storylines”) and examine how they might play out across space. The Scenario Generator offers a relatively simple method of generating scenarios based on user-defined principles of where land changes could occur and the possible extent of these changes. It can be used to create alternate futures, the likely outcomes of which can be compared using InVEST. It is downloaded within InVEST, but can be used to generate potential future landscapes without running any additional InVEST models. Read its userʼs guide here. Go to ScenarioHub
This tool estimates the relative importance of regions for human use. Outputs can help decision-makers weigh potential conflicts among spatially-explicit management options that involve new activities or new infrastructure. The output maps help visualize hotspots of land or ocean use, and areas where the compatibility of various activities should be investigated when drafting new zoning or permitting schemes. It is downloaded within InVEST. Read its userʼs guide here.
This tool delineates watersheds for points of interest along a stream network (e.g., drinking water intake points, hydropower facilities, reservoirs). Using a DEM, DelineateIT identifies the area upstream of points of interest and creates watershed maps for use as inputs to InVEST freshwater models or for other analyses. DelineateIT is available as module within the InVEST software package, but useful without InVEST. Read its user’s guide here.
RouteDEM calculates flow direction, flow accumulation, slope and stream networks from a DEM using the d-infinity flow direction algorithm. RouteDEM outperforms routing algorithms as implemented in other free and proprietary GIS software. RouteDEM is available as a module within the InVEST software package, but also useful without InVEST. Read its user’s guide here.
InVEST Dashboards automate common synthesis and visualization tasks that may be necessary after running an InVEST model. With the dashboards, you can explore InVEST outputs in a web browser with interactive maps and charts, share results with colleagues by simply sending a link, and spend less time fussing over layer symbologies in GIS and more time exploring results. Try our dashboards for three InVEST models: coastal vulnerability, recreation, and habitat risk assessment (HRA).
InVEST can be integrated into more complex workflows and analyses by using its Application Programming Interface (API) within the Python programming language. InVEST is available for download on the Python Package Index, and API documentation is available online.
