Inland lakes or reservoirs are the main surface water resources, related to people’s survival and social development. On-site level data critical for resource management, while satellite laser remote sensing a significant tool long-term change monitoring. In this study, we took Miyun Reservoir, most important source of drinking in Beijing, as research area. We used Landsat images Ice, Cloud, Land Elevation Satellite (ICESat-2) small-scale monitoring inversion across unrecorded periods....
Abstract. The GaoFen-7 (GF-7) satellite is successfully launched on November 3, 2019, and its laser altimeter system officially firstly employed as the main payload for earth observations in China, which includes two sets of altimeters footprint cameras. Laser Footprint Image (LFI) used to capture spots ground. In order make up shortcomings high cost field work traditional ground detector-based calibration method, this paper proposes a novel method based LFI. Firstly, spaceborne model Camera...
Abstract The Gaofen‐7 (GF‐7) satellite is China's first submeter high‐resolution optical stereo‐mapping satellite. equipped with two area‐array laser footprint cameras to capture the spots emitted by altimeters. To accurately identify and locate geographical positions of spots, a stepwise geometric calibration method ground laboratory information for camera proposed in this paper. It includes internal external calibration. First, initial values camera's parameters are determined based on...
In order to improve the efficiency of remote sensing satellite, with limited performance existing optical payload, a satellite constellation construction idea combining low and high resolution is proposed. The working mode narrow-area high-resolution guided by pre-processed information on wide-area low-resolution satellite. Full using onboard memory pre-installed base map, satellites only transmit changes self-update, effectively reduce transmission pressure data. on-board processing...
