An ERS‐1 SAR image of Frankfurt was geocoded using a variety of DEM spatial resolutions to examine the influence on positional accuracy compared with control points derived from a 1:50 000 scale map of the same area. It was demonstrated that mapping to 1:50 000 scale was possible in flat areas with a DEM resolution finer than 200 m. The case for SAR imagery in nautical charting is discussed in the light of these results, drawing on recent experiences at the Hydrographic Office in charting the South Orkney Islands.
