BLOCK ADJUSTMENT The block adjustment was carried out using the BLOKK suite of programs provided with the CARTO Instruments AP190 analytical stereo-plotter. Several combinations of the control points were used to find the optimum selection. The best results have an RMS error of x60 m horizontally, w 58°57 98:551 68:53" 70°32 Figure 4 A map of the same region as fig. 3, compiled from satellite imagery at 1:250,000 scale in 1978. and +15 m vertically. The various combinations of points used are shown in Fig. 2, and the corresponding errors in Table 1. The lowest errors were obtained from test 1, which only contained 6 control points. Although this is more than the minimum number required to control the block, the distribution of control points is weak, particularly in the lower left quadrant. Test 2 used all the available control and thus improved the distribution of points. Unfortunately, the error is much higher, suggesting that some of the control points are in error. Test 3 was designed to investigate the accuracy of the points derived from the shape-from-shading algorithm. This gave very good results but the distribution of control is unacceptable since the left- hand end of the block completely lacks control. However, the low error figures, especially in the vertical dimension, shows that the shape-from-shading algorithm has proved reliable. Test 4 attempted to add control to the left-hand side of the block and the poor result shows that some of the points in the lower left corner must have large errors. This is the only test where the vertical error is unacceptable. Test 5 used all the points with measurements in three dimensions, and the result is comparable with that from test 3; it gives a better distribution of control but the lower left corner is still unsupported.
