GIS data acquisition and GIS data projects

  1. GIS data

The following GIS data listed below were purchased for use in various GCRO projects :

    • Afrigis: Bizcount geocoded business layer, gated communities
    • GeoTerraImage (GTI): 2009 provincial land cover, urban land cover (2.5m resolution), growth indicator (2001 – 2009), and land use (2001-2009)
    • GeoTerraImage (GTI): Growth Indicator – land use per building (62 sub classes, providing a full classification of land use activities across the urban areas in Gauteng
    • GeoTerraImage (GTI): Growth Indicator – development initiatives. A spatial dataset illustrating submitted, refused and approved applications and potential future growth such as rezoning of existing cadastre and township developments on farm portions and agricultural holdings
    • GeoTerraImage (GTI): Growth Indicator – demography. Based on the 2001 official StatsSA census, demographic statistics (gender, age, race and total population) are associated with each residential dwelling point (2001) to provide a fine scale analysis of the demographic situation. An indication of the 2010 demographic dynamics and population update is provided by AfricaScope (Mr Craig Schwabe) through demographic analysis and forecasting
    • DemProKey X from Lightstone: Census 2001 and updated 2010 income and demographics per EA (Enumerator Area from Census 2001) and 2011 ward boundaries
    • Deeds transfers and property valuation per EA from Lightstone: average Deeds transfers per EA as well as number of properties/transactions in various price bands from 1993-2010, and average valuation per EA based on Lightstone’s Automated Valuation Model (AVM) per EA from 2007-2010. 

 As part of the licencing agreement GCRO negotiated with the data providers, these datasets are also available for use by both Wits/UJ students and lecturers, and can be viewed in the Economic and Spatial Structure themes in the GCRO GIS website, accessible via the Interactive GIS page.

Other key datasets include:

  • GCRO 2009 Quality of Life survey
  • StatsSA: Census 2001 and Community Survey 2007 datasets
  • Satellite imagery including: SPOT and Quickbird Satellite imagery from the CSIR Satellite Applications Centre and Landsat imagery from 1989/91, 2000/01 and 2009
  • Municipal Demarcation Board: Administrative boundaries (wards, local municipalities, etc.) and base data (such as main roads, railways etc.)
  • GPG Department of Economic Development: Development Planning  - all the Gauteng provincial GIS datasets
  • GPG Department of Roads and Transport: GPG base transportation data sets
  • Department of Human Settlements – investment potential atlas, community protest atlas
     
  1. GIS Projects

GCRO is working with Brian Mubiwa from University of Johannesburg on an urban growth mapping project. Mubiwa is currently working on his doctoral thesis titled: Impact of Transport Corridors on Urban Development and Transport Energy in the Gauteng Global City Region. Analysis outputs for the thesis will include a mapping of the GCR urban landscape over the past 20 years. GCRO assisted Mubiwa with obtaining Landsat satellite imagery for 1989/1991 and 2000/2001 and 2009.
