APPLICATION OF TM AND SAR IMAGES FUSION FOR LAND MONITORING IN COAL MINING AREAS

摘要

The defection of single data source can be solved with fusion between TM and SAR images. It provides a better solution for land surface monitoring in the mining areas. Results of experiment showed that the fusion images can be integrated the advantages of each one, enhanced the recognition ability of features, improved land use/land cover classification accuracy. Further discussed the method of microwave remote sensing for ecological environment monitoring in mining areas, it is pointed out that the SAR images can be quantitative analysis of hydrogeological environment, the growth of crops and vegetation, land cover and soil resources, the INSAR images can be extracted collapse and change information. Research shows that the use of multi-source and multi-temporal images, fusion technology of TM and SAR images, could be favorable of dynamic monitoring for the ecological environment in mining areas, and provided basic data for exploitation of mining resources.
