Name: 5m Contours

Display Field: NAME

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: 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 5m 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 2 blocks in the year 2023. The southern half of the City was flown in Jan 2023 and the northern half was flown in Dec 2023. The point cloud has a density of 10 points per square metre and a vertical accuracy of 0.1m (95%). The contours are derived through bipolar interpolation from the 5m DEM (raster) model. The height reference used is the SA Land Levelling Datum.
