We assessed vegetation cover density and distribution in Eastern Jordanian rangeland reserves (2411 km2) using a series of Landsat images (34 year’s period) ground survey (2020) to identify proper sites for reintroducing Arabian Oryx (Oryx leucoryx). The natural were Burqu Nature Reserve site-1, site-2 (Dmetheh), Al Dahek Reserve. Satellite sensor data from Landsat-8-OLI Landsat- 5-TM used deri...

Background and Purpose: Rapid assessments of forest damage caused by natural disasters such as ice-break, wind, flooding, hurricane, or forest fires are necessary for mitigation and forest management. Forest damage directly impacts carbon uptake and biogeochemical cycles, and thus, has an impact on climate change. It intensifies erosion and flooding, and influences socio-economic well-being of ...

The Mehdiabad zinc-lead deposit, which is located at the East of Mehriz city, is a carbonate-hosted ore deposit lying in the dolomitic rocks of Taft Formation. This deposit is composed of oxide-carbonate and sulfide ores. Different spectral processing techniques were applied to ASTER and Landsat 8-OLI multispectral images to detect different mineralization zones and associated alterations. In O...
