Journal Article
Published: 23 May 2018
Environmental and Engineering Geoscience (2018) 24 (2): 221-235.
... Detection and Ranging (LiDAR) and field data were integrated into a Geographic Information System to understand the origin, kinematics, and subsequent history of the landslides. Products derived from the bare-earth LiDAR data include an engineering geomorphology map, shaded relief maps, and several LiDAR...

...-relief areas of the Scottish Highlands, may exhibit pulses of rapid late Cenozoic exhumation that may be attributable to Quaternary climate change. Some aspects of published local exhumation histories conflict with the offshore depositional record ( Knott et al., 1993 ; Doré et al., 2002 ; Stoker, 2002...

... and erosion rate in steep, rocky landscapes. We analyzed two sites in southern California, USA, that share similar lithology and hydroclimate, but that differ in tectonic setting, bedrock fracture density, sediment grain size, and relief structure. Multi-scale analysis of lidar point clouds reveals...

... to the Kendall, Valparaiso, and Lake Border moraines to the west. Immediately north of the village of Otsego, the Kendall moraine (Fig. 2 ) consists of low- to moderate-relief hummocky topography, including several flat-topped hills with a maximum relief of ~18 m (60 ft).

The flows filled and locally topped the existing landscape forming broad plateau-like flats. Topographic relief...
