Terrain analysis means examining the landscape using remote sensing and other desktop data sources such as air photos, satellite images, and digital terrain models. Terrain analysis is used in a wide range of applications such as gravel exploration, identification of geohazards (e.g., slope failures), groundwater exploration, and historical site analysis. In many cases, critical information about a site can be generated through terrain analysis, which can guide subsequent field investigations.
