Service Description:

 This 5m Digital Elevation Model is a raster elevation model (bare earth) derived from the 2019B LiDAR dataset. The purpose of the CCT GLM 2019 is to provide a set reference surface for Existing Ground Level across the City of Cape Town Municipality. The Ground Level Map was approved by the City Council on the 27th July 2023. It consists of this 5m DEM (raster) and 2m Contours (vector). The 5m DEM is derived from the LiDAR2019B dataset (consisting of the 2018, 2019A and 2019B datasets). The DEM has a vertical accuracy of 30cm. The height reference used is the SA Land Levelling Datum and the SAGEOID2010 was employed. The City of Cape Town Ground Level Map 2019 is defined in the City of Cape Town Municipal Planning Amendment By-law, 2019 as: “‘City of Cape Town Ground Level Map’ means a map approved in terms of the development management scheme, indicating the existing ground level based on floating point raster’s and a contour dataset from LiDAR information available to the City”.
