 "description": "The City of Cape Town Ground Level Map 2019 is defined in the City of Cape Town Municipal Planning Amendment By-law, 2019 as: \u201c\u2018City of Cape Town Ground Level Map\u2019 means a map approved in terms of the development management scheme, indicating the existing ground level based on floating point raster\u2019s and a contour dataset from LiDAR information available to the City\u201d.Contour lines connect a series of points of equal elevation and are used to illustrate topography, or relief, on a map and can be drawn at various desired intervals. This dataset displays contours drawn at every 2m height interval. Numerous contours that are close together indicate hilly or mountainous terrain; and when far apart, they represent a gentler slope. The contours were derived from LiDAR (Light Detection and Ranging) data that was captured in 3 blocks in the years 2018 to 2019. The LiDAR point cloud has a density of 2 to 3 points per square metre at a vertical accuracy of 0.1m (95%). The contours are derived through bipolar interpolation from the 5m TIN model. The height reference used is the SA Land Levelling Datum and the SAGEOID2010 was employed.",
