摘要：A dig! taJL 'terrain model(D'rl"I) represents a topographic surfacein terms of a set of spatial coordinates.ln sampling the surfac~to establish a D'rr1, we often face on such problems: the determiih~ing of adequate sampling density in order to meE:3t_a given speel~fications and the evaluating of t.he accuracy of 'the obtAin~~ DTIYJ..Ho,," accurately a topographic surface is represented by a DTIVI dependsessentially on the such several factors:sampling density,measuring errors,interpolation method and terrian classification.,etc.It is important to develop a method of the accuracy estimationand find the relationship between the ~ccuracy and the thesefactors ..
