Extraction of fractional vegetation cover in arid desert area based on Chinese GF-6 satellite
Open Geosciences, 2021 The red edge band is considered as one of the diagnosable characteristics of green plants, but the large-scale remote sensing retrieval of fractional vegetation coverage (FVC) based on the red edge band is still rare.

Identifying Spatial and Temporal Characteristics of Land Surface Albedo Using GF-1 WFV Data
, 2021 Land surface albedo (LSA) is an important parameter that affects surface–air interactions and controls the surface radiation energy budget. The spatial and temporal variation characteristics of LSA reflect land surface changes and further influence the ...

Comparison of Simulated Multispectral Reflectance among Four Sensors in Land Cover Classification
Remote Sensing, 2023 Multispectral images accessible free of charge have increased significantly from the acquisitions by the wide-field-of-view (WFV) sensors onboard Gaofen-1/-6 (GF-1/-6), the Operational Land Imager (OLI) onboard Landsat 8 (L8), and the Multi-Spectral ...

Coastal Zone Classification Based on Multisource Remote Sensing Imagery Fusion
Journal of Sensors, Volume 2018, Issue 1, 2018., 2018 The main objective of this paper was to assess the capability of multisource remote sensing imagery fusion for coastal zone classification. Five scenes of Gaofen‐ (GF‐) 1 optic imagery and four scenes of synthetic aperture radar (SAR) (C‐band Sentinel‐1 and L‐band ALOS‐2) imagery were collected and matched.

Journal of Sensors, Volume 2016, Issue 1, 2016., 2016 Due to the high similarity of the spectra of urban water and building shadows, high‐resolution satellite imagery often confuses and wrongly classifies these features. To address this problem, we propose an object‐based method for distinguishing building shadow from water using an artificial bee colony algorithm. In the method, four spectral ratio bands
