Terrestrial laser scanning is of increasing importance for surveying and hazard assessments. Digital terrain models are generated using the resultant data to analyze surface processes. In order to determine the terrain surface as precisely as possible, it is often necessary to filter out points that do not represent the terrain surface. Examples are vegetation, vehicles, and animals. Filtering ...

High-resolution topographic and stratigraphic datasets have been increasing applied in active fault investigation seismic hazard assessment. There is a need for the comprehensive analysis of faults on basis correlating geomorphologic features data. The integration TLS GPR was adopted to characterize 3D geometry Maoyaba segment Litang fault. used obtain high-resolution data establishing surficia...

We examine portage sites in the U.S. South, Mid-Atlantic, and Midwest, including those on the fall line, a geomorphologic feature in the southeastern U.S. marking the final rapids on rivers before the ocean. Historically, waterborne transport of goods required portage around the falls at these points, while some falls provided water power during early industrialization. These factors attracted ...
