The coupled development of terrain and vegetation : the case of semiarid grasslands
… in semiarid grasslands. Remotely sensed data and digital elevation maps are used to infer the relationship between vegetation cover and topographic attributes at two field sites in the semiarid southwestern United States. A positive relationship between drainage area (a proxy for water …

Path planning for human planetary surface Exploration in rough terrain
… with rough terrain captured in high resolution digital elevation maps(DEM). Next, the thesis discusses results and lessons learned from using SEXTANT during two BASALT deployments in basaltic terrains in Idaho and Hawaii. Finally it goes into details on interfaces that were built to complement …

A Comparison of Habitat and Geomorphic Changes on East Ship Versus Sand Islands Mississippi, 2007-2014
… to rapid changes in habitat, geomorphology, and elevation by natural and anthropogenic disturbances, such as hurricanes, subsidence, sea-level rise, and dredging activities. The purpose of this study was to compare elevation, total volume, habitat-type coverage, and short-term change between …

UHF-SAR and LIDAR Complementary Sensor Fusion for Unexploded Buried Munitions Detection
… 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 UHF-SAR …

Anisotropic variational models and PDEs for inverse imaging problems
In this thesis we study new anisotropic variational regularisers and partial differential equations (PDEs) for solving inverse imaging problems that arise in a variety of real-world applications. Firstly, we introduce a new anisotropic higher-order total directional variation regulariser. We …
