GIS data acquisition and GIS data projects
- Chris Wray
Data is key to understanding and visualising trends in the Gauteng City-Region (GCR). A significant spatial and non-spatial database has been built up in the first phase of GCRO’s establishment and initial 3-year strategic plan, through the negotiation of access to, and acquiring of GIS data from, a variety of public and private sector sources. The data formed the basis of number of research projects, such as the urban space economy, OECD Territorial Review of the GCR, intersection between sustainability and disaster vulnerability, green assets and infrastructures, understanding spatial change in the GCR and the peripheries and rural/urban transitions project. The visualisation of the data in new and innovative ways has also resulted in successful map of the month outputs, which have visually highlighted key issues affecting the (GCR). Public access to the data was made possible through the GCRO GIS website where the spatial data remains available to be viewed and overlaid on all the other GIS layers within the website. Data was also made available to students and staff members at both UJ and Wits to promote the use of spatial data for cutting edge urban research. Over the past two years, GCRO assisted with over 50 individual requests for spatial data in the GCR.
As such, there was a need to update some the existing GIS data layers and purchase new data sets to feed into the research. This project worked as a mechanism through which GIS data needs were determined, and data was purchased. All data was purchased on condition that the it may also be utilised by both UJ and Wits students and staff for research purposes.
