The Calculation of Curvature for a PSR Terrain Using ArcGIS

The curvature of a terrain is a useful tool to assess its topography, as it helps to identify areas of potential erosion or deposition. Knowing the curvature of a terrain can also provide insight into the processes that have formed the terrain, such as fluvial or glacial activity. In this article, we will discuss the steps to calculate the curvature of a PSR (Planar Slope and Relief) terrain using the ArcGIS software (Liaw, 2017). The first step is to create a digital elevation model (DEM) of the terrain, which can be done through a variety of methods, such as LiDAR or aerial photography. The DEM should be of sufficient resolution to accurately represent the terrain. Once the DEM is created, it should be imported into the ArcGIS software. From there, the PSR terrain can be created by using the ‘Surface Slope and Relief’ tool. This tool creates a representation of the terrain that displays the planar slope and relief of the terrain (Liaw, 2017). The next step is to calculate the curvature of the terrain. This can be done by using the ‘Surface Curvature’ tool. Cont…
