A Method of Fast Search and Location of Irregular Triangular Grid Model
摘要
Abstract
Triangular grid model has the advantage of high precision in interpolation,but it isusually slow in interpolation and deficient in construction and management. This paper pro pounds a method of locating a trangle efficiently based on a special method of constructingtriangular grid,i. e we manage triangular grid through quadrangle grid. We made an experi ment with a route from Xian to Yanan and compared the interpolation result with the gidmodel of RACAD system. We draw the conclusion that the interpolation precision of triangu lar grid model is higher.关键词
