Raster Based Spatial Data Analysis A raster is a GIS data structure comprised of a matrix of rectangular grid cells. Each cell represents a specific area on the ground. Resolution of raster is defined by the ground area represented by the raster grid cell. The higher the resolution of the gr...

Various spatial analysis problems exist in many scientific fields such as geology, geophysics, oceanography, agriculture, ecology, environmental science, geography, sociology, politics, anthropology among others. So far, commercial GIS software provided only very simple analytic functions of overlay and cla...
According as general houses' prices data, this paper, based on spatial analysis function of Geographic information system(GIS), using semi-variogram of spatial statistics, studies spatial heterogeneity of general houses' prices distribution in Dongguan quantitatively. The results from the analysis indicate...
