The 1:250 000 topo-cadastral maps show topographical detail with the addition of names, numbers and boundaries of original farms, the boundaries ofmagisterial districts, and provincial and international boundaries. Elevation, depicted by means of contours at 100m intervals (50m on sheets prior to 2000), is further enhanced by hypsometric tints, i.e. shades of brown becoming progressively darker as elevation increases. This series is a firm favourite for regional planning and administrative purposes.
These sheets are derived from the larger scale 1:50 000 topographical maps with some detail of necessity being generalised, i.e. thinned out to show only the more important features. 70 maps of this series cover South Africa. Each sheet generally covering an area of one degree of latitude and two degrees of longitude.
Projection : Gauss Conform, with the central meridian the nearest odd meridian.
