Digital terrain modelling of catchment erosion and sedimentation / Hua Sun
… and interfaced with the existing digital terrain models called TAPES-C and THALES, to estimate soil erosion and deposition in Sauerbier Creek catchment.

A user interface for terrain modelling in virtual reality using a head mounted display
… of creating content, specifically designing terrains, for use in immersive environments using VR technology. To do this, we develop a VR interface for terrain creation based on an existing desktop application. The interface incorporates a head-mounted display and 6 degree of freedom …

Large-scale 3D environmental modelling and visualisation for flood hazard warning.
… The work consists of three main parts: digital terrain modelling; 3D environmental reconstruction and system development; flood simulation models. The digital terrain model is constructed using real world measurement data of GIS, in terms of digital elevation data and satellite image data. An …

Climate Change and Potential Economic Impacts in Ireland: The Case for Adaptation
… vulnerability and inland flooding. Digital Terrain Modelling is used in conjunction with a range of datasets to examine vulnerabilities relating to coastal land, commercial and residential property addresses, insurance claim costs, as well as wetland and species vulnerability. It should be …

Digital Terrain Models for Radio Path Loss Calculations
This work addresses the problem of digital terrain modelling for estimating radio path propagation within a mobile communication system. The ideal requirements are for a data structure which is storage efficient and computationally efficient for calculating profiles, whilst elevation errors should …

Implication of Terrain Topology Modelling on Ground Vehicle Reliability
… excitation input to a vehicle as it traverses terrain is provided by the surface topology. It is not computationally efficient to utilise physically measured terrain topology for these simulations since extremely large data sets would be required to represent terrain of all desired types. …
