Locality of Topographic Ground Truth Data for Salt Marsh Lidar DEM Elevation Bias Mitigation Using Machine Learning
<p>Light detection and ranging (lidar) digital elevation models (DEMs) are crucial for modeling coastal salt marsh systems, simulating the coastal dynamics of sea level rise (SLR), and predicting storm surge inundation depth and duration. Improvements in lidar acquisition technology and data …

UHF-SAR and LIDAR Complementary Sensor Fusion for Unexploded Buried Munitions Detection
… surface anomalies/changes act as confusers. LIDAR digital elevation models (DEM) provide georegistered information about the above-surface objects present in the UHF-SAR scene. Detection of the above-surface objects in the LIDAR domain is used to rule out above-surface false-alarms in the …

Terrain characterization for site selection and preparation
… a stale a priori digital elevation model (DEM) was merged with a high-resolution, updated LIDAR DEM using the mblend method. The mblend method achieved better results than the traditional cover method by ensuring fewer height discontinuities along the edge of the two DEMs. To perform land …

Rain Induced Runoff Simulation Using A 2D Numerical Model
… watershed using high resolution data such as LiDAR topography to validate that the model can be applicable to problems with a variety of spatial scales and complexity. Infiltration and subsurface flow is not considered throughout the study. The model’s capability of simulating the rainfall …

Remote sensing for geomorphic and hydrodynamic modeling and process understanding
… and inundation extent) are affected by drone lidar DEM resolution and computational mesh resolution over 1.5 km of Stroubles Creek in Blacksburg, Virginia, USA. This was done by running several simulations of a hydrodynamic model with various resolutions of computational mesh (1 m and 2 m) and …

Assessing the uncertainties of Radar and LiDAR derived digital elevation information over static and dynamic terrain
… is validated over an urban area using airborne LiDAR, for which the side-looking nature of synthetic aperture radar and the variations in wavelength depending on penetration depth are observed as the principal factors influencing uncertainty over built and vegetated environments. Sand dune …
