The method for obtaining geometric topological information of CAD Models from STEP files is discussed, and a STEP based direct slicing method is proposed.
The information of ground thermal field and soil vertical zonality which differ with elevation is extracted by using the TM6 thermal infrared image to make the pseudo-color-equidensity slicing;
