Research on Remote Sensing Dynamic Monitoring of Ecological Resource Environment Based on GIS

SPOT and ETM+ satellite images are used as the main source of information. The remote sensing image processing software ERDASIMAGINE and the geographic information system software ARCVIEWGIS have been used. The technical method and work flow of remote sensing dynamic monitoring of resources and ecological environment based on GIS are studied. The geometric correction, registration, filtering, fusion and information extraction of remote sensing images have been completed. Data mining and professional maps based on GIS are produced and updated. The key techniques are analyzed and studied. In addition, the natural ecological environment of the region was evaluated.
