| Abstract: | While carrying out thematic elements extracting based on satellite imagery, it is an efficient way for dealing with the limitation of the multi-spectrum data in their resolution to use comprehensive geographic information, GIS technology has several processing functions to merge the imagery with the geographic information to improve the classification precision. The classified image data were composited with those of the basic topographic elements and a high quality thematic map of the present land uses was obtained as output on a colour scanning plotter. |
