Abstract:
In last few years, researchers are studying highly level of accuracy for land surface study fields using remote sensing science. We used the data of MODIS satellite image that has 500 m resolution on this study. This study were focused analysis of image preprocessing and change detection on whole territory of Mongolia. Using SRTM and Landsat TM satellite images since 2001 and 2015. In study time, decreasing specifications were estimated by area on each zones such as 1.12 percent on forests, 0.26 percent on high mountain steppe, 3.64 percent on dry steppe and 4.40 percent on desert steppe. But increasing specifications were estimated by area on each zones such as 6.87 percent on steppe, 0.30 percent on open shrub lands, 2.01 percent on sparsely vegetated, 0.16 percent on permanent wetlands and 0.08 percent on others. In generally we made conclusion that change detection was lower and nothing change on 78 percent (316894.75 km square) of total territory of Mongolia. However, increasing specification (positive change) was 20 percent (1234067.5 km square) and negative change specification was 2 percent (23185.75 km square) of total area.
