Extracting accurate terrain in vegetated areas from ICESat-2 data

International Journal of Applied Earth Observations and Geoinformation, 2023
The uncertainty of ICESat-2 terrain accuracy, especially in vegetated areas, limits its scientific application, and there is barely any comprehensive modeling evaluation for this uncertainty.

A Combined Deconvolution and Gaussian Decomposition Approach for Overlapped Peak Position Extraction From Large-Footprint Satellite Laser Altimeter Waveforms

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
In satellite laser altimetry, it is a challenging task to accurately extract peak positions from full waveforms due to the overlapped or weak peaks within the large laser footprints, which substantially affects the subsequent applications.

Reducing spatial autocorrelation in the dynamic simulation of urban growth using eigenvector spatial filtering

International Journal of Applied Earth Observations and Geoinformation, 2021
In cellular automata (CA) based modeling of dynamic urban growth, non-spatial statistical approaches are usually affected by spatial autocorrelation and fail to describe the spatially non-stationary relationships between urban growth and its drivers. The

Geology of the Kuiper quadrangle (H06), Mercury

Journal of Maps, 2022
The Kuiper quadrangle (H06) is located at the equatorial zone of Mercury and encompasses the area between 288°E – 360°E and 22.5°N – 22.5°S. Using the NASA MESSENGER data, we compiled a geological map of the quadrangle at a 1:3,000,000 scale. The mapping
