Precisely measuring the Earth's changing surface on decadal to centennial time scales is
critical for many science and engineering applications, yet long-term records of quantitative …

This paper explores the feasibility of using historical aerial photographs and digital
photogrammetric procedures to reconstruct morphometric landscape changes in a …

Declassified historical imagery from the Hexagon spy satellite database has near-global
coverage, yet remains a largely untapped resource for geomorphic change studies …

With the ongoing digitization in archives, an increasing number of historical data becomes
available for research. This includes historical aerial images which provide detailed …

Archival aerial imagery is a worldwide resource for documenting past 3-D change at very
high-resolution. However, external information is normally required so that accurate 3-D …

Observing changes in Earth surface topography is crucial for many Earth science
disciplines. Documenting these changes over several decades at regional to global scale …

Photogrammetry and geosciences are closely linked since the late 19th century. Today, a
wide range of commercial and open-source software enable non-experts users to obtain …

Unmanned aerial vehicles (UAVs) and structure‐from‐motion photogrammetry enable
detailed quantification of geomorphic change. However, rigorous precision‐based change …

The application of structure-from-motion (SfM) to generate digital terrain models (DTMs)
derived from different image sources has strongly increased, the major reason for this being …

High-resolution topographic surveying is traditionally associated with high capital and
logistical costs, so that data acquisition is often passed on to specialist third party …
