Two orders of wall‐to‐wall geographic data

Area, EarlyView.
Short Abstract The use of the term ‘wall‐to‐wall’ to describe geographically extensive data without any singular definition in the remote sensing and geographically related analysis. This work presents an assessment of the application of the term in the scientific literature. Abstract From personal observations of recent published works, the term “wall‐

Performance Assessment of ICESat-2 Laser Altimeter Data for Water-Level Measurement over Lakes and Reservoirs in China

Remote Sensing, 2020
Although the Advanced Topographic Laser Altimeter System (ATLAS) onboard the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) was primarily designed for glacier and sea-ice measurement, it can also be applied to monitor lake surface height (LSH ...

Delete---ICESat-2 leaf area index (LAI) Retrieval Comparisons

, 2021
This is the first release of the LAI used for the submitted paper: Guo et al., 2021: Exploring photon-counting laser altimeter ICESat-2 in retrieving LAI and correcting clumping effect. The grid LAI derived from airborne LiDAR data was used to validate the LAI derived from ICESat-2, which has been validated by the field measurements and has the spatial

Lead and Floe Detection From CryoSat‐2 Radar and ICESat‐2 Laser Altimetry

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Differences in satellite sampling affect their ability to resolve small‐scale features over Arctic sea ice. For CryoSat‐2 (CS2) and ICESat‐2 (IS2) these differences are driven by geometric (footprint resolution) and radiometric (radar or laser) sampling.

Advancing Near‐Real‐Time Flood Inundation Mapping in Australia

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Floods are the second‐most deadly natural hazard in Australia, following heatwaves. Monitoring flood extent and depth in near real‐time (NRT) is crucial to minimize loss of life and socio‐economic impacts. This study leverages advanced computing, data management systems, and high‐quality data, including river gauge data APIs and Australian ...

Dynamic Boundaries of Antarctic Active Subglacial Lakes Reveal Underestimated Water Volume Change and Overestimated Lakebed Active Area

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract This study revisited 158 documented active subglacial lakes across Antarctica, applying a height‐change anomaly delineation algorithm to CryoSat‐2 and ICESat‐2 satellite altimetry data to assemble a 14.75‐year (2010.5–2025.25) time series of active subglacial lake dynamics.

ICESat GLAS Altimetry Measurements: Received Signal Dynamic Range and Saturation Correction [PDF]

, 2017
NASAs Ice, Cloud, and land Elevation Satellite (ICESat), which operated between 2003 and 2009, made the first satellite-based global lidar measurement of Earths ice sheet elevations, sea-ice thickness and vegetation canopy structure.

Water Storage Changes of Lakes and Reservoirs Across Asia (2018–2023) and Their Effects in Flood Control

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Monitoring lake and reservoir water levels is critical for water resource management and flood risk mitigation. We integrate Sentinel‐3A/B and ICESat‐2 altimetry to reconstruct monthly water levels (2018–2023) for 7,433 lakes and reservoirs (>5 km2) across Asia and estimate their storage variations.

Evaluating and comparing the performance of ICESat-2 and GEDI data for estimating aboveground biomass in mangroves

International Journal of Digital Earth
The launch of the ICESat-2 and GEDI spaceborne LiDAR missions has provided new opportunities for large-scale estimation of mangrove aboveground biomass density (AGBD); however, their footprint-scale performance remains unclear.
