Abstract : The concept of map comparison is treated in a general manner for thematic, regularly gridded maps. Three methods of map comparison, direct methods, trend surface, and spatial autocorrelation, are investigated. The direct methods and trend surface method are applied to artificial surfaces and subsequently to regularly gridded maps of the pollutant total suspended particulates. A method of forming spatial or two dimensional autocorrelation maps is presented. A strategy based on these methods, is described whereby a large number of regularly gridded maps can be readily compared. (Author)
