Welcome to the interactive GCRO GIS Viewer, which provides access to spatial data describing the Gauteng City-Region (GCR). The GIS website will run on the main Internet browsers such as Internet Explorer (version 6 and higher), Firefox and Safari.

New data themes just released include:

  • 50 priority wards with an interactive table and dynamic maps derived from 18 indicators.
  • Spatial change (urban land cover change from 1991 to 2009)
  • Environmental data (various GDARD environmental layers)

New features include:

  • Blank base layer: an option for users with slow Internet connections to switch off the Google Maps base layers or utilise a blank background for a clearer display of the GCRO themes
  • OpenStreetMap base layer
  • Screen print option to include graphs or legend in a map print
  • Option to download graph data into an .csv file
  • Google Street view tool
  • Load data tool for users overlay and view their own data in the GCRO GIS website.The data must be in one of the following formats: ESRI map service, OGC Web Map Service, Shp file (must be a zipped file less than 2 Mb in size and utilise the WGS84 Web Mercator projection, to ensure it overlays the Google Maps base maps and GCRO layers) and KML/KMZ file (limited 2Mb file size)

To start using the viewer, select one of the various base data layers (including Google Maps) using the base maps tools, or interact with specific GCR data themes to view and graph with the GCRO dynamic data tools.

Background

The GCRO GIS website was developed as an interactive tool to assist both local and provincial governments, to better understand the Gauteng City-Region and make informed decisions about development in the GCR. The application, launched in September 2010, allows the user to visualize GCR base data and themed layers, by offering different perspectives of the GCR, such as population distribution, economic datasets and the latest 2009 Quality of life survey results as maps and graphs.
 
The main users of the application are considered to be the GCRO stakeholders – Gauteng Provincial Government (GPG) Planning commission, GPG Office of the Premier, Local government officials and other GCR government agencies. The site was also made publically accessible through the GCRO website, providing open access to the Gauteng City-Region GIS data.
