[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 HWSD used the spatial information provided by the FAO-UNESCO Digital Soil Map of the World (DSMW) and national/regional maps, along with soil profile information to create a global-scale map of soils. 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. |

Biodiversity indicator values (scores) for grid cells at 1-kilometer resolution, based on several pieces of information including total counts (presence) of mammals, birds, amphibians and reptiles from IUCN and Birdlife International, total counts or presence, of critically endangered and endangered mammals, birds, amphibians and reptiles, the presence of endemic species/ species unique to the region, extinction risks for species over 50, 100 and 500 years, and biome vulnerability, identified from the WWF ecoregions. |
