هدفت هذه الدراسة إلى تطبيق نموذج المعادلة العامة لفقدان التربة (RUSLE) لتقدير قابلية للتعرية في حوض وادي بريشو، الواقع الشمال الغربي من قضاء ئاكرى . واتبع الباحث دراسته المنهج الاستقرائي للمعطيات المختلفة ليتبلور خلال متغيرات منها: الارتفاع الرقمي (DEM)، بيانات خصائص ، والمرئية الفضائية (Landsat8)، والبيانات المناخية، ثم انتقل التعامل معها بيئة نظم المعلومات الجغرافية (GIS) عبر برنامج (ArcMap 1...

Forest cover dynamics is a critical global problem that affects the socio-economic and ecological function of forest landscape in globe The Earth's continuously altered by several climatological anthropogenic factors. And its change influence world carbon cycle biodiversity pool at local, regional scale. Lume district Ethiopia one potential area has important function. Currently, despite their ...

Cloud detection is a key step in optical remote sensing image processing, and the cloud-free of great significance for land use classification, change detection, long time-series landcover monitoring. Traditional cloud methods based on spectral texture features have acquired certain effects complex scenarios, such as cloud–snow mixing, but there still large room improvement terms generation abi...

Accurate and detailed spatial soil information is essential for environmental modelling, risk assessment and decision making. The use of Remote Sensing data as secondary sources of information in digital soil mapping has been found to be cost effective and less time consuming compared to traditional soil mapping approaches. But the potentials of Remote Sensing data in improving knowledge of loc...

An outbreak of Ulva prolifera poses a massive threat to coastal ecology in the Southern Yellow Sea, China (SYS). It is necessity extract its area and monitor development accurately. At present, monitoring by remote sensing imagery mostly based on fixed threshold or artificial visual interpretation for selection, which has large errors. In this paper, an adaptive model Google Earth Engine (GEE) ...

The Asian elephant (Elephas maximus Linnaeus) is a globally endangered species, an internationally protected and first-class animal in China. However, future climate change human activities exacerbate the instability of its habitat range, leading to possible reduction range. By using multi-source remote sensing data products, as well models, including ASTER GDEM v3, Landsat8 OLI image ClimateAP...
