【Abstract】 To counter the splice problem of digital terrain model (DTM) the paper puts forward the algorithm of cutting out of splice line to triangle network. It also introduces for details the basic principle and the main course. The program drawn up by this algorithm implements a fine connection between digit and model so that the digit and model meet the requirement of building three-dimensional model.更多还原
