InVEST Models

InVEST® is free to download and use, and its source code is open. InVEST models are spatially-explicit, using maps as information sources and producing maps as outputs. The models are based on production functions that define how changes in an ecosystem’s structure and function are likely to affect the flows and values of ecosystem services across a land- or  sea-scape. The spatial resolution of analyses is also flexible, allowing users to address questions at local, regional, or global scales. InVEST models enable connections to be made to the locations and people benefiting from the ecosystem service, as well as to monetary valuation. Some of the models themselves include simple forms of valuation.

InVEST models are distributed with the InVEST Workbench as a standalone desktop application or with the natcap.invest Python package. InVEST is independent of a GIS software, but you'll need mapping software and geoprocessing skills to prepare the model inputs and fully explore your results. The tool is modular in the sense that you do not have to model all the ecosystem services listed, but rather can select only those of interest.
