Figure 13 and 14 represent the outlines of the roads before and after automatic compilation. Figure 13 shows the 
result after the stereo plotting. Figure 14 is a result of the automatic compilation. The lines show roads, and break

According to our experiment, the result of the first pattern is 100.0 % of 158 places done successfully. Second pattern is 93.8 % of 16 
places. Third pattern is 60.0 % of 5 places. Fourth pattem is 75.0 % of 4 places. Fifth pattem is 82.9 % of 35 places. Sixth pattern is 
95.8 % of 71 places. Seventh pattern is 86.6 % of 97 places. Total 93.2 % of 386 places where compilation was necessary involved all 
seven patterns and it was successfully compiled.
