GGRETA: Governance in Transboundary Aquifers

This is the GGRETA Information Management System (IMS), which IGRAC developed for data collection and analysis done for the GGRETA Project. The main objective of the GGRETA IMS is to provide users an online platform to consistently collect, organise, analyse and disseminate the information collected for the transboundary aquifers’ assessment that has been carried out in the case study areas in Central America, Southern Africa and Central Asia. The availability of a common information system facilitates cooperation between aquifer states and provides a tool to all stakeholders involved in the governance of the aquifer.

To enable storage, processing and visualization of the collected data a online information management system was developed. This IMS operates as a data and information sharing platform between the countries for the assessment and management of the transboundary aquifer. The newly developed information management portal is integrated into IGRAC’s Global Groundwater Information System (GGIS). The GGIS is using open and extendable state of the art technology, making it possible to connect to more and more varied external data sources and systems on the internet.

Protected and Public Workspace 

The GGRETA IMS has two different workspaces: the public viewer, freely accessible to anyone with internet access, and the protected workspace, which is a password protected and exclusively available to registered and authorized GGRETA users. In this protected workspace, users can manage the groundwater information related to the aquifer or region they are responsible for. The public viewer on the other hand enables the general public to navigate through a map view and search for information such as aggregated values or spatially distributed data of parameters and indicators values derived from the assessment.

The GGRETA Viewer contains: 

  • A map view to visualise data and information on a geographic location 
  • A catalog containing all map layers with data structured in a systematic way 
  • A features panel providing tabular output of the data

What users can do in the GGRETA IMS:

  • Store and visualize indicators, variables, thematic maps, documents and images
  • Analyse an discuss results in a protected workspace before making it publically visible
  • Add map layers from external sources making use of web map services (WMS)
  • Generate new pieces of information by creating overlays of thematic maps
  • Build advanced queries on attributes tables

Your project Groundwater Information System

The modular set-up of the system allows for an easy development of a dedicated IMS for new projects. A new IMS can be developed as a stand-alone application or, if preferred, further integrated with existing modules available in the GGIS. In the last years, the GGIS has demonstrated its capacity in the GGRETA projects as well as in other transboundary aquifer assessment projects.
