Identify the location and spatial extent of an area that provides ecosystem services and where beneficiaries are located.

WW is a web-based tool for modelling hydrological services associated with specific activities under current conditions and under scenarios for land use, land management and climate change. It provides quantitative biophysical results or relative indices that can be used to understand hydrological ecosystem services, water resources and water risk factors. Using WW does not require GIS or modelling skills.

SolVES is an ArcGIS-dependent application that allows the user to identify, assess and map the perceived social values that people attribute to cultural ES, such as aesthetic or recreational values. Combining spatial and points-allocation responses from surveys (which can be undertaken in person, online or through mailing), it produces points-based social-values metric and raster maps of social value intensities. Using SolVES requires GIS.

InVEST is a suite of software models for mapping and quantifying ES in biophysical or economic terms under different scenarios (e.g., policy or management options). InVEST models are based on simple, generalised production functions and require commonly available input data. Using InVEST requires GIS but not modelling skills.
