Abstract
To improve the efficiency of spatial analysis a novel model is proposed. Based on analyzing on workflows and techniques, the research mainly put emphasis on optimizing data organizations, enhancing data accessing efficiency, improving spatial researches, simplifying complex operations, and realizing automation. The model employed ArcGIS Engine, ArcSDE and ADO.net to design and implement its functions through programming under the Dot NET Framework. It has been applied to the grading work of agricultural lands in Lanping County, Yunnan Province, which shows that it can simplify operations, improve accuracy, and has features of good practicality and generality and should be applicable in other settings and over larger extents.
