However, | dimension, has proved he left-hand hat some of large errors. al error is points with he result is os a better rner is still attempts to strengthen control in the lower left corner but point 2004 is apparently poorly located, and the errors are unacceptable. The overall result of these tests was that the distribution of control in test 5 represented the best that could be achieved in this project. The results, while not comparable with the levels of accuracy to be obtained in temperate countries, are acceptable for mapping in this remote region. À further advantage is that the relative accuracy of measurements within the block is of the order of 1-2 m. The lower absolute accuracy is less important for practical use. RESULTS The output from the block adjustment was used with the AP190 analytical plotter to extract heights from one of the models of the block. Heights could only be reliably extracted on ridge-lines, on exposed rock and where crevasses or avalanche scars provided enough surface detail for stereo-matching on ice-covered surfaces. These elevations gave enough height control for the shape-from- shading algorithm described above to be used to extend contours onto the snowfields surrounding the central ridge. The map created (fig. 3), with contours at an interval of 25 m, can be compared with an earlier map (fig. 4), compiled at a scale of 1:250,000, which was the most detailed line map of the area available prior to this work. ACKNOWLEDGEMENTS Dr. J. Sievers, Institut für Angewandte Geodäsie, Frankfurt, provided the georeferenced TM image. Mr. A. Perkins and Mrs J.W. Thomson, British Antarctic Survey, provided much helpful discussion. Dr R. Kirby and Dr C. Place, University of Edinburgh, were supervisors to RS during this project, which was undertaken as part of her MSc course.
