چکیده
This study takes multitemporal Landsat images as data source to explore the changes of Fractional Vegetation Cover (FVC) and ecological quality (EQ) Wugong Mountain (WGM). The regression model obtained from MODIS NDVI was used correct temporal difference normalized vegetation index (NDVI) in 2019, Remote Sensing based Ecological Index (RSEI) calculated assess change FVC EQ WGM. Results showed that, past 25 yr, mean value has increased 0.795 1994 0.890 which consequently improved 0.746 0.773 respectively. relationship among topographic factors, analyzed by using elevation, slope, aspect. effect factor on WGM order aspect, elevation. RSEI first then decreased with increment elevation slope. In detail, favorable terrain area an 500–1,400 m a slope 8°–35°. semi-sunny sunny slopes were higher than that shady slopes. unfavorable meadow greater 1,700 m. work highlights importance can provide scientific decision-making for sustainability WGM, coordinate development environment protection economic construction.

Snow cover area is one of the most important criteria to calculate snow melt runoff. This can have an effect on the biology of the plant and the environment of a region. Using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. Most of the useful methods in calculating snow cover area are based on satellite i...

متن کاملSegmentation Improvement of High Resolution Remote Sensing Images based on superpixels using Edge-based SLIC algorithm (E-SLIC)
The segmentation of high resolution remote sensing images is one of the most important analyses that play a significant role in the maximal and exact extraction of information. There are different types of segmentation methods among which using superpixels is one of the most important ones. Several methods have been proposed for extracting superpixels. Among the most successful ones, we can r...
متن کاملHigh Efficient Classification on Remote Sensing Images Based on Svm
Automatic image categorization using low-level features is a challenging research topic in remote sensing application. In this paper, we formulate the image categorization problem as an image texture learning problem by viewing an image as a collection of regions, each obtained from image segmentation. Our approach performs an effective feature mapping through a chosen metric distance function....
