Abstract:

Research of a high-resolution remote sensing images and automatic monitoring of land changes based on GIS data. Were used three kinds of fuzzy classification and data fusion classification of the study area. combined with the historical period GIS thematic data and classification results based on highly accurate classification results, calculated the corresponding polygons category ingredients and comparative analysis of its historical properties, and automatically monitor change of land use. The experimental results show that the fuzzy decision fusion classification can significantly improve the classification results, to obtain more accurate results than a single classifier. Decision classification results combined with GIS data changes in regional decision experimental results show that there is a big change in the region able to accurately automatically determine change area, area less part of the change part of misjudgment phenomenon.
