摘要:Many cities in the second and third world experience currently strong urbanization and are expanding fast. These development dynamics are so strong, that the traditional maps as a basis for planning are often out of date or are in certain cases just not available. However, to monitor, control and guide these development trends, up-to date maps are needed as a basis for urban and regional planning. We will show in our contribution how a new form of digital map – a photo-textured Digital Terrain Model (DTM) with integrated information for planning measures - can be produced efficiently and used in the planning process: For the study area of named "Greater Kunming Area" we produced a DTM. Then we geocoded and orthorectified LANDSAT 7 ETM MS and IRS-1C PAN satellite images. In a special process of image fusion we combined the information of high spectral information (MS – Multi-spectral with 30 m pixelsize) and high metric resolution (PAN – Panchromatic, 5 m pixelsize) to a joint image representation. Planning information is used as a third layer of data. The combined datasets can be interpreted as a photorealistic 3D map, which can be accessed and represented by modern visualization tools. Finally we show how such a 3D digital model can be used for illustrating planning approaches
