Abstract: The formulas of error propagation for nonliner model are given and improved in order to be simplified and be really used in practice, and its application in error analysis and procession of spatical data of GIS are discussed. This paper studies its importance and use fulness for spatial data of GIS and draws a conclusion that nonlinear error propagation really describles accuracy.
