【Abstract】 A new method for TIN generation based on adjacent contours is brought forward, called algorithm of region segmentation. The fundamental thinking is introduced in details. Finally, experiments about mountaintop, saddle and valley(or ridge) are carried out, which manifests the validity of the method.更多还原
