Differencing multi-temporal topographic data (radar, lidar, or photogrammetrically derived point clouds or digital elevation models—DEMs) measures landscape change, with broad applications for scientific research, hazard management, industry, and u

Topographic differencing measures landscape change by comparing multitemporal high-resolution topography data sets. Here, we focused on two types of topographic differencing: (1) Vertical differencing is the subtraction of digital elevation models (D

Scientific research has always struggled with problems related to reproducibility caused in part by low data sharing rates and lack of provenance. Credibility of the research hypothesis comes into question when results cannot be replicated. While the
NASA’s spaceborne laser altimeter, ICESat-2, sends 10,000 laser pulses per second towards Earth, in 6 separate beams, and records individual photons reflected back to its telescope. From these photon elevations, specialized ICESat-2 data products f

High-resolution topography (HRT) is a powerful observational tool for studying the Earth's surface, vegetation, and urban landscapes, with broad scientific, engineering, and education-based applications. Submeter resolution imaging is possible when c
