A dataset of high-resolution digital elevation models of the Skeiðarársandur kettle holes, Southern Iceland.

In studies of the relief evolution of smaller landforms, up to several dozen meters in width/diameter, digital elevation models (DEMs) freely accessible in different repositories may be insufficient in terms of resolution. Existing geophysical or photogrammetric equipment is not always available due to costs, conditions and regulations, especially for students or young researchers. An alternative may be the handy-held ground-based Structure from Motion technique. It allows us to obtain free high-resolution DEMs (~0.05 m) using open-source software. The method was tested on kettle holes of the glacial flood origin on Skeiðarársandur (S Iceland). The material was collected in 2022 at two outwash levels of different ages and vegetation cover. The dataset is available in the Zenodo repository; the first part is data processed in point clouds and DEMs, and the second includes original videos in MOV format. The data can be used as a reference to assess changes in the kettle hole relief in subsequent research seasons, as a methodological study for other projects, or for didactic purposes.
