How to calculate the curvature for a PSR terrain in Arcgis what steps ?

Calculation Curvature of a PSR Terrain using ArcGIS

It is useful to determine the curvature and topography of terrains. This helps identify potential erosion areas or deposition. The curvature can be used to determine the origins of the terrain. We will be discussing the steps required to calculate the slope and relief curves of PSR (Planar Slope and Relief), terrain with ArcGIS software. (Liaw 2017, 2017). It is necessary to first create a digital terrain elevation model (DEM). This can be achieved using various methods such as LiDAR and aerial photography. It should have sufficient resolution to represent the terrain accurately. After the DEM has been created, the DEM should be exported to ArcGIS. From there, the PSR terrain can be created by using the ‘Surface Slope and Relief’ tool. The tool generates an image of terrain showing the slope and the relief (Liaw 2017, 2017). Next, calculate the curvature. This can be done by using the ‘Surface Curvature’ tool.
