2013 Treatise on Geomorphology  
Synopsis (50-100 words) Geovisualisation, the depiction of spatial data, is key to facilitating the generation of observational datasets through which Earth surface and solid Earth processes may be understood. This chapter focuses upon the visualisation of terrain morphology using satellite imagery and DEMs, where manual interpretation remains prevalent in the study of geomorphic processes. Techniques to enhance satellite images and DEMs in order to improve landform identification as part of

Visual interaction with spatial data is an important part of exploring and understanding geomorphological datasets and a variety of methods ranging from simple overlay, panning and zooming are discussed, along with 2.5D, 3D and temporal analyses. Visualisation outputs are outlined in the final section, which focuses on static and interactive methods of dissemination. Geomorphological mapping legends and the cartographic principles for map design are introduced, followed by details of dynamic webmap systems that allow a greater immersive use by end users, as well as the dissemination of data.
