Fractional vegetation cover (FVC) is an essential land surface parameter for Earth surface process simulations and global change studies. The currently existing FVC products are mostly obtained from low or medium resolution remotely sensed data, while many applications require the fine spatial resolution FVC product. The availability of well-calibrated coverage of Landsat imagery over large are...

one of the serious problems of iran’s watersheds is soil erosion and can be considered as one of the main obstacles to achieve sustainable agricultural development and natural resources. in most countries of the world, because of absence of accurate data for the sediment erosion, deposition utilizing models to estimate erosion is inevitable. in order to apply effective management in natural res...

This research utilized various methods for extracting soil characteristics from Landsat 8 OLI/TIRS imagery in the Thua Thien Hue province, Vietnam. In this study, Object-Based Oriented Classification (OBOC) method was used to extract information about land cover (focusing on rock outcrops) basis of TGSI, NDVI, and NDBI indicators. The moisture determined by examining correlation between Land Su...

Remote sensing analysis is a crucial tool for monitoring the extent of mine waste surfaces and their mineralogy in countries with a long mining history, such as South Africa, where gold and platinum have been produced for over 90 years. These mine waste sites have the potential to contain problematic trace element species (e.g., U, Pb, Cr). In our research, we aim to combine the mapping and mon...

As sensor parameters and atmospheric conditions create uncertainties for at−sensor radiation detection, radiometric consistency among satellite images is difficult to achieve. Relative normalization a method that can improve multi−image with accurate pseudo−invariant features (PIFs), especially over large areas or long time series images. Although there are algorithms manually automatically sel...

The increased demand for natural resources, economic growth and graph can influence the reduction of individual land use coverage, which makes water infiltration difficult. objective was to evaluate, through morphometric parameters land-use occupation, flooding susceptibility in Campestre creek watershed. An analysis indexes performed with help tools presented SPRING 5.4.3 software. characteris...
