| Abstract: | The paper mainly aims at the terrain map of1:50000rates.Some improved algorithms are discussed in the paper.They are pre-processing algorithms for raising the connection rate of contour.They can correctly distinguish wide contour from thin contour according to the width information of contour.The contour can be correctly connected by us-ing the information,avoiding wrong connection between wide contour and thin contour. |
