Attribute Data

Attribute Data is presently managed by using the following systems:

NGA

The National Groundwater Archive (NGA) The National Groundwater Archive (NGA) is a centralised web enabled database and accessible 24 hours a day. All clients with a direct interest in groundwater can register to search, capture and store data. Registered users can also extract data directly via the Internet.

To register go to: http://www3.dwa.gov.za/nganet

Enquiries: ngaur@dws.gov.za

The NGA is populated with in excess of 263 750 Geosites across the country, only point data.

To obtain Geosite Identifiers contact the relevant Regional Office

The spatial distribution of borehole records is also available.

WMS

The Water Management System (WMS) provides CHART with over 34 370 groundwater macro element samples, containing over 601 068 individual laboratory macro parameter analysis, including data from the National Groundwater Quality Monitoring Programme (NGwQMP).

Data request can be sent to Georequest Service at georequests@dws.gov.za.

HYDSTRA

This application contains surface, groundwater and rainfall data.  Data from the Groundwater Level Monitoring Network is included.

Data request can be sent to Georequest Service at georequests@dws.gov.za.

Spatial Data

Spatial Data is generally available in GIS format – coverages or shape files. The geodatabase is an ARCGIS GEODATABASE storing all cleaned and verified spatial hydrogeological data. Groundwater related spatial data that are available are for example.

Queries can be sent to Georequest Service at georequests@dws.gov.za.
