3D Path-finding in a voxelized model of an indoor environment

Indoor environments can be complex and need to be represented by a 3D representation. This is especially important for 3D path-finding. 3D features of the environment can have an effect on the computed path and these features can not be represented correctly in a 2D representation. A voxelized model is a good 3D representation that supports path...

Mapping Urban Surface Infiltration Capacity: Segment-based land cover classification with VHR imagery for urban water management and design.

Effective urban water management requires certainty about surface conditions such as the surface infiltration capacity (SIC). A SIC map of an urban catchment area could be a useful input for evidence-based urban design of water-sensitive/low-impact neighbourhoods and multitiered water management schemes for reducing flood vulnerability. Methods...

Filling the white gap on the map: Photoclinometry for glacier elevation modelling

In this study the limits and potentials of the principle of photoclinometry for glacier elevation modelling is assessed. A combination of optical and laser remote sensing instruments are used to map the surface of different remote ice bodies. Loss and gain of a glaciers' mass is a good indicator for local climate. If mass-balances of glaciers...

Analysis of Pedestrian Crowd Movements at Lowlands

Several pedestrian crowd events that became disasters occurred in the last decade. Most of these events were either religious festivals, sport or music events. Even though these events are organized frequently, not a lot is known about pedestrian crowd movements. One of the key problems in the analysis is the lack of crowd movement data....

Laser scanning modelling of a Cessna citation: For Computational Fluid Dynamics (CFD) Studies

In Aerospace Engineering the field of Computational Flow Dynamics (CFD) studies the aerodynamic behaviour of aircrafts. What is currently being used to perform CFD simulations are Computer Aided Design (CAD) models of the airplanes, which are usually low-detail industrial design models. Research of new methods for improving the results of the...
