Mapping Soil Salinity Prediction Enhanced by Time‐Series Remote Sensing Features

Land Degradation &Development, EarlyView.
ABSTRACT Gaining timely knowledge of soil salinity's spatiotemporal dynamics is crucial for accurate mapping. Through temporal span comparisons, this study systematically extracts and utilizes time‐series features (TSFs) derived from Sentinel‐2 and Landsat 8 NDVI and SAVI data (2019–2023) to enhance prediction accuracy. Three datasets were constructed:

Multi-temporal Green Roof Vegetation Assessment Using Sentinel-2: A Pilot Study [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The City of Toronto has reported having over 1,000 green roofs (GRs) since implementing its green roof bylaw, but their conditions are not systematically monitored and require a remote, cost-effective method. Satellite remote sensing has proven useful in

Band-Based Best Model Selection for Topographic Normalization of Normalized Difference Vegetation Index Map

IEEE Access, 2020
Topographic effect in remote sensing images is severe in high mountainous areas. Efficiently to reduce the effects, several topographic normalization models have been proposed. Since the performance of the models is largely dependent on the spectral band

Assessing Soil Erosion in a Typical Karst Region: A Model Improved by Bedrock Exposure Rate in Guizhou Province

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion is a major environmental challenge in karst regions of Southwest China, where thin soils and high bedrock exposure accelerate land degradation. This study modified the RUSLE model by incorporating bedrock exposure rate to improve erosion simulation in Guizhou Province from 2000 to 2024.

Integrating Ecosystem Service Benefits to Assess Ecosystem Health and Its Response to Land Spatial Structure Conflicts in Anning River Basin, China

Land Degradation &Development, EarlyView.
ABSTRACT Land spatial structure conflicts (LSSC) weaken the actual benefits of ecosystem services by inducing trade‐offs among them, directly threatening regional ecosystem health (EH) and sustainable development. However, most studies have failed to incorporate ecosystem service benefits (ESB) into EH assessments and have overlooked their response to ...

Using Data Mining Techniques to Forecast the Normalized Difference Vegetation Index (NDVI) in Table Grape

Proceedings of the 8th International Conference on Operations Research and Enterprise Systems, 2019
The Normalized Difference Vegetation Index (NDVI) is a simple indicator that quantifies aerial biomass in fruit crops, which is correlated with the fruit yield and quality produced by an orchard. Therefore, knowing the NDVI values would allow predicting productive parameters above mentioned, which in turn would help planning operational activities such

Impact of Road Network Development on the Spatiotemporal Soil Erosion in the Three‐River Source Region

Land Degradation &Development, EarlyView.
ABSTRACT As a vital water conservation region in China, the Three River Source Region (TRSR) plays a critical role in safeguarding regional ecological security and ensuring the sustainable utilization of water resources. In this study, the Revised Universal Soil Loss Equation (RUSLE) was employed to quantify soil erosion in the study area across three ...
