The spatial analysis of raster data makes up the basis of GIS spatial analysis,and is also the kernel of the ArcGIS spatial analysis module. The authors studied the application of raster data spatial analysis to urban land grading in the city of Dazhou,Sichuan Province,which included the partition of the grading cell,the obtaining of all kinds of distances in the process of grading,the calculation of the effective values of all kinds of grading elements and the integration of effective values as well as the drawing of all kinds of effective value contours. It is concluded that the raster data spatial analysis tool can play a very important role in the urban land grading,and therefore has broad prospects in future application.
