Recreational trails are a vital element of protected natural areas (PNAs) infrastructure, which enables visitors to travel through and engage in various activities such as hiking, biking, horse riding. Degradation of trails adversely affects the natu

Two detailed geomorphological maps (1:2000) depicting landscape changes as a result of a glacial lake outburst flood were produced for the 2.1-km-long section of the Zackenberg river, NE Greenland. The maps document the riverscape before the flood (5

A 1:850 detailed map of the geomorphology of the Dynamisk Creek alluvial fan on Svalbard was produced based on very high-resolution data collected using an unmanned aerial vehicle (UAV) in 2014. The map documents features within the surface of the fa

The fully automated Structure-from-Motion approach for developing digital elevation models and orthomosaics has been known and used in photogrammetry for at least 15 years. Years of practice and experience have allowed researchers to provide a solid

A 1:19,500 map of the Petunibukta region documents the spatial distribution of almost 300 colluvial and alluvial fans (together with their catchments) in the periglacial high-Arctic environment of Svalbard. Fan-shaped landforms were mapped using an o

The response of temperate glaciers to rapid climate warming is reflected in the geomorphology (landsystem) resulting from snout recession. This paper develops a locally diverse process-form model of active temperate glaciers through mapping and quant

This study presents the operational framework for rapid, very-high resolution mapping of glacial geomorphology, with the use of budget Unmanned Aerial Vehicles and a structure-from-motion approach. The proposed workflow comprises seven stages: (1) Pr

Rapid glacier advance is known to occur by a range of mechanisms. However, although large‐scale debris loading has been proposed as a process for causing rapid terminus advance, it has rarely been observed. We use satellite remote sensing data to o
