This inter-disciplinary technical session will highlight developments driving innovation in the exciting uses of digital landscapes (DEM, DTM, or DSM) of the Earth, seafloor or planetary terrains. It aims to bring together ‘users’ analysing digital landscapes to exhibit the best methods and computational techniques, cross-fertilize best practice, and illustrate what can be achieved and what challenges remain. Possibilities (e.g. innovations), problems (e.g. awkward case studies), solutions and interesting geomorphic uses are encouraged.

We believe that objective, robust and reproducible quantitative methods underpin our ability to unlock the potential wealth of new insights into geomorphic processes recorded in DEMs.

Much interest is expected in high-resolution DEMs, but any data source (e.g. laser scanning, SAR, photogrammetry, satellite-derived) is welcome. Fusion between topographic data and other measurements is in scope.

In geomorphic processes we include both natural processes and those creating a human fingerprint in the landscape. Features identified or parameterised could include volcanoes, craters, gullies, fault scarps, drumlins, or those reflecting anthropogenic disturbances such as deforestation, new urban areas, or land-use change. Natural processes constrained could range from mass-wasting to volcano formation, and from flooding to sedimentary deposition.

We encourage early stage researchers to present their studies
