African cities are growing fast but many are unable to respond to the challenges of urbanization because old colonial plans did not include marginalized poor populations. Town planners are struggling to cope with the environmental management consequences of urbanization.
A Global Human Settlement Layer (GHSL) application, developed by the EC’s Joint Research Centre (JRC) is substantially contributing to enabling the human settlements authorities in mapping built-up areas to monitor and plan monitoring spatial infrastructure developments. JRC and SANSA customized the GHSL application to enable SANSA to process their archived SPOT-5 imagery that date back until the year 2006.
SANSA is currently processing the human settlements historical layers and plans to partner with other African agencies in the future to produce human settlements data for other Africa countries that do not have access to high resolution human settlement data. Availability of SPOT 6/7 satellite imagery in South Africa allows SANSA to continue updating the National Human Settlement Layer.
The success of the South African National Development Plan and SDGs also relies on availability of accurate spatial data. The human settlement data is one of the base datasets required during the implementation and monitoring of the set outcomes and development goals. Human settlement data developed using the GHSL application is currently being used in South Africa to support a number of legislations including Spatial Planning and Land Use Management Act; National Human Settlements Land Inventory Act; Statistics Act; Municipal Demarcation Act; Conservation of Agricultural Resources Act; Disaster Management Act and Electoral Act.
