Abstract : Software has been developed to provide the following displays of digital terrain elevation data with a given map area: (a) A contour plot with one or more visibility diagrams, (b) An oblique view of the map area from any azimuth or elevation angle, (c) A perspective view of a specified sector from a selected viewpoint, and (d) A point-to-point line-of-sight profile. Emphasis has been placed on making the software easy to use, on generating the displays as quickly as possible, and on making effective use of colour. Keywords: Colour, Datum(Elevation), Terrain, Mapping, Australia.
