Abstract: The research is conducted with the problem of extracting ground fissure information in mining area. The UAV and TM images are used as data sources. Through the extraction of texture feature,linear characteristics,fractal dimension,the NDVI values and spectral features,and using the ERDAS software,a knowledge model is built,and the distribution graphs about ground fissure information is successfully extracted. It proves that the method has higher precision after precision verification on the extraction results.
