Abstract Two experimental, digitally produced and enhanced, 1:250 000 scale Landsat mosaic maps are described. The first is a map of the Kingdom of Lesotho, produced in collaboration with the Lesotho Director of Surveys and Mapping. It consists of a mosaic of four contiguous Landsat scenes, collected on two consecutive days, digitally enhanced and overlaid with conventional map data (political boundaries, roads, etc). The map is expected to provide useful information on topography, landforms, etc. for planning purposes. The second map, produced in collaboration with the South African Geological Survey, is an experimental map sheet of the Barberton area, consisting of a digital mosaic of two contiguous Landsat scenes. By means of a colour space transformation, stratigraphic geological map information in digital form was combined with the terrain information as contained in the first principal component of the Landsat data.
