| Abstract: | This method is to draw up 1:100,000 map of land resource evaluation. Multi-source information comprehensive mapping method refers to one that chooses aerial and space remote sensing and surface materials for analysis and evaluation under the computersupervised classification of data, and is supplimented by relevant materials and referencesources.This method may employ aerial photographs, as well as SPOT satellite pictures and remote sensing data computer supervised classification graphs, depending on the demands and possibilities of drawing a land resource evaluation map. For maps of the provincial level, it is proved to be more accurate and convenient to use computer supervised classification of remote sensing data. In order to get the expected result from multi-source, information comprehensive mapping method, it necessary to make good use of the information from computer supervised classification and other relevant remote sensing and non-remote sensing information, solve the components of map delineation in a scientific way, standardize the boundary shape. Finally, field check of the map should be done carefully.1:100,000 map of land resource evaluation compiled by this method has had a check field and has been registered with SPOT satellite pictures and remote sensing data comoputer supervised classification graphs. Its accuracy rates are 88, 91 and 93(%) respectively. |
