The disposal, modeling and visualization of 3D data are very important in the construction of digital earth. Now, one can get fine 3D model with software such as 3DMax and so on. But the 3D system is only perfect in visualization without any function of spatial analysis. The predominant software of GIS, for example, ArcGIS, or IMAGIS, provides ideal(More)
The Simulation of heavy metal contamination in surface soils has been discussed in the paper. Instead of the acquisition of the “best” estimation of unsampled points, the author paid much attention to the assessment of the spatial uncertainty about unsampled values. The simulation method of Geostatistics, aimed at the same statistics(More)
