Solution for TIN Creating from Contour for Digital-Agriculture Using Based on Recursive Thought

TIN date is wildly used in digital-agriculture area, but there is a drawback in TIN creating from Contour, especially in agriculture-application, that is flat-triangle. Some researchers have study on this and a lot algorithm have been brought out, in this paper, a improved algorithm of solving the problem about flat-triangle is proposed base on recursive thought. This algorithm is used in the 863-project of Nation, have been proved that is more simply and effective than other but can get a satisfactory result.
