Abstract In 1904, Dr. H. G. Fourcade compiled the first recorded topographic map made using analytical stereophotogrammetric methods. This paper describes how, in 1985, the stereophotography was repeated in very close proximity to Fourcade's original camera base using a modern metric camera. A new topographic map was compiled by computer graphics from stereoscopic observations made on a modern stereocomparator. A direct comparison of the two sets of interpolated contour lines demonstrates that Fourcade produced a highly accurate map covering part of Devil's Peak which is adjacent to Table Mountain near the city of Cape Town.
