GGIS-Global Groundwater Information System (IGRAC)

The Global Groundwater Information System (GGIS) is an interactive, web-based portal to groundwater-related information and knowledge. The GGIS consists of several modules structured around various themes. Each module has its own map-based viewer with underlying database to allow storing and visualizing geospatial data in a systematic way.

GIS Portal is a database of the boreholes located within refugee camps and settlements. The database contains information on the infrastructure, hydrogeology, lithology, and water quality parameters. This information is linked to the Knowledge Attitudes and Practices (KAP) mapper which analyses data from the household survey. It also has the potential to be used for asset management, and groundwater and water quality monitoring purpose.

Water Data Portal (IWMI)

Water Data Portal (IWMI)The Water Data Portal (WDP), following "one-stop shop" approach, provides access to a large amount of data related to water and agriculture. WDP contains meteorological, hydrological, socio-economic, spatial data layer, satellite images as well as hydrological model setups. The data in the WDP, both spatial & non-spatial, are supported by the standardized metadata and are available for download by user including academia, scientists, researchers and decision-makers. However, access is provided in compliance with copyrights, intellectual property rights and data agreements with our partners.
