What is the GGIS?

The GGIS is the Global Groundwater Information System. It is an online platform supporting the sharing of groundwater data and information worldwide. It was created by the International Groundwater Resources Assessment Centre (IGRAC) to advance the assessment of groundwater resources and make knowledge accessible to those who depend on groundwater or are engaged in groundwater management, development or protection.

The very first version of the GGIS was launched in 2004. It has been upgraded several times since then. The current version was launched in January 2021. As in previous versions, it supports the sharing of map layers and documents. In addition, the GGIS now includes a section for sharing well data and groundwater monitoring data. Before, groundwater monitoring data were shared in a separated application, the GGMN Portal. Another breakthrough is that the GGIS now operates as a Spatial (and temporal) Data Infrastructure (SDI), where several individuals and organisations can connect for sharing data. Map layers and well and monitoring data shared in the GGIS are open, it is therefore not required to register to access content. Registering is only required for users who want to upload material in the GGIS.
