The number of Earth observation satellites carrying optical sensors with similar characteristics is constantly growing. Despite their similarities and the potential synergies among them, derived satellite products are often developed for each sensor independently. Differences in retrieved radiances lead to significant drops accuracy, which hampers knowledge information sharing across sensors. T...

Burn scar extraction using remote sensing data is an efficient way to precisely evaluate burn area and measure vegetation recovery. Traditional burn scar extraction methodologies have no well effect on burn scar image with blurred and irregular edges. To address these issues, this paper proposes an automatic method to extract burn scar based on Level Set Method (LSM). This method utilizes the a...

Daily fractional snow cover (FSC) products derived from optical sensors onboard low Earth orbit (LEO) satellites are often discontinuous, primarily due to prevalent cloud cover. To map the daily cloud-reduced FSC over China, we utilized clear-sky multichannel observations from the first-generation Chinese geostationary orbit (GEO) satellites (namely, the FY-2 series) by taking advantage of thei...

Abstract Urban Heat Island (UHI) phenomenon is a particular climate change impact in urban areas that can trigger adverse effects on environmental conditions. This effect usually worsened by increasing anthropogenic activities. While the of UHI has mostly been studied metropolitans around world, few studies are presented investigating outcome mid-sized cities. study aims to assess spatial distr...

Detailed information on the spatial-temporal change of impervious surfaces is important for quantifying the effects of rapid urbanization. Free access of the Landsat archive provides new opportunities for impervious surface mapping with fine spatial and temporal resolution. To improve the classification accuracy, a temporal consistency (TC) model may be applied on the original classification re...

Algal bloom is a serious global issue for inland waters, posing pose threat to aquatic ecosystems. The timely and accurate detection of algal blooms critical their control, management forecasting. Optical satellite imagery with short revisit times has been widely used monitor in marine large waters. However, such images typically are coarse resolution, limiting utility map small We developed ne...

Soil salinity is a major concern in the Uzbekistan. Fergana valleys agricultural lands, it negatively affects plant growth, crop yields, whereas central part of valley semi-desert and desert areas due to subsidence, corrosion ground water quality, leading further soil erosion land degradation. Traditional assessments have been doing by collecting samples laboratory analyzing collected for deter...
