Global Human Settlement Layer data for census analysis in South Africa
GHSL R2022 South Africa showcase
Accurate population and household census information are critical data input for national policymaking process. They facilitate informed development decisions on the delivery and planning of services related to governance and public health, such as election preparation, response to disasters, or human and structural risk assessment.
In this report we investigate, how census related activities can benefit from combining official statistics with new geospatial information derived from remote sensing imagery. We test how GHS-BUILT-S layer – a high resolution, spatially and temporally comprehensive dataset on residential built-up surface areas produced by the Global Human Settlement Layer project, could have supported census processes, using South Africa national census data from years 2001 and 2011 as a case study.
Findings of our study show that GHS-BUILT-S layer enables the identification of dynamically changing regions and thus has the potential to improve the operational process of the population and housing census in four dimensions: planning, preparation, field work, and validation and verification. In particular, the case study of South Africa showcases a wider field and scope of application of the operational production of global information on built-up surfaces and population distribution to be continuously produced by the Copernicus Emergency Management Service, Exposure Mapping Component (Copernicus GHSL).
