Abstract : The authors have applied the thought of image data base to creating the Large-Scale Three-Dimensional
Remote Sensing Image (L3DRSI), and put forward the new method “dividing-integrating”. The specially processed large
DEM data are divided into small blocks, and texture mapping of RS image with these DEM data is performed in two ways.
Finally, the L3DRSI is created. The new method can not only improve the precision of terrain which is very important
for L3DRSI, but also enrich the information and enhance the practicability of LRSI3D.
