[1] Neugarten et al. (2018) review a larger number of tools, including Tessa, MIMES, PABAT, and Co$ting Nature and WaterWorld. The latter are closed-source platforms that provide easy entry points for ecosystem services modelling, see: http://www.policysupport.org. Co$ting Nature (Mulligan et al., 2020) is a web-based tool for analysing ecosystem services, that departs from a large number of pre-loaded global data sources. The analysis is spatially explicit (1km2 or 1ha2), and it has wide functionality for doing policy scenario analysis. WaterWorld has the same approach, but focuses on hydrological services. It can be used to assess water, land use and climate policies. Both platforms allow the user to upload own data sources.

The database uses FAO classifications at the soil unit level (FAO-74, FAO-85, FAO-90).  Aside from mapping information (classification, ID, etc.), a further range of characteristics are included at the topsoil (0 to 30cm) and the subsoil (30 to 100cm) level.

These data are then used to monitor changes in underground water storage, the amount of water in large lakes and rivers, soil moisture, ice sheets and glaciers, and sea level caused by the addition of water to the ocean.   

Base products are 1 degree, updated monthly. Approaches to disaggregate to finer spatial resolution exist.
