Method Research for Geological Disaster Survey and Monitoring Based on GF-2 Satellite Data Processing:Taking Hunan Xinhua Demonstration Zone as an Example

ZOU Pu;China University of Geosciences;Hunan Provincial Geological Environment Monitoring Station ( Changsha);  
The successful launch of GF-2 satellite signs that the remote sensing monitoring of 1 m resolution can be achieved in our country. In order to popularize the GF-2 satellite data in geological disaster survey and monitoring area more quickly,the methods of geological disaster survey and monitoring are researched in this paper. The experiments show that the DOM by GF-2 data of demonstration area can meet the plane precision of 1∶ 10 000 scale and the DOM can be appropriate for geological disaster survey and monitoring. Based on several experiments,the results indicate that combination method by Band1,Band4 × 0. 25 + Band2 × 0. 75 and Band3 can produce the best results,and fusion by Gram-Schmidt Spectral Sharpening has a good effect.
