The World-wide Hydrogeological Mapping and Assessment Programme (WHYMAP) provides data and information about the major groundwater resources. The programme compiles data on groundwater from national, regional and global sources, and visualises them in maps, web map applications and services. The generated products provide information on quantity, quality and vulnerability of the groundwater resources on earth and help communicating groundwater related issues to water experts as well as decision makers and the general public.
