Global Groundwater Information System (GGIS)

Global Groundwater Information System (GGIS)

The Global Groundwater Information System (GGIS) is an interactive, web-based portal to groundwater-related information and knowledge. The main purpose of the system is to assist in collection and analysis of information on groundwater resources and the sharing of this information among water experts, decision makers and the public.

The GGIS consists of several modules structured around 6 themes. Each module has its own map-based viewer with underlying database to allow storing and visualizing geospatial data in a systematic way.

GGIS Portal Capabilities:

  1. Store variables, thematic maps and documents.
  2. Visualise geospatial data and information in a map viewer.
  3. Share and analyse results in a protected environment before making it publically available.
  4. Add map layers from external sources via web map services (WMS).
  5. Generate new pieces of information by creating overlays of thematic maps.
