Examining the influence of urban design on cyclist route choice in different weather conditions

With regard to climate change and air pollution within cities, interest in sustainable modes of transportation for regular use has taken a rise. Utilitarian cycling is being seen as a frontrunner for replacing everyday motorized travels within and between cities, supported by the rapid emergence of the electric bicycle. Governments are trying to...

From static to dynamic visualization of the sea surface height on a web GIS application

During the last three decades, the Earth’s climate is changing rapidly, with higher average temperatures every year that leads not only to the melting of the ice sheet in the arctic and on most of the glaciers all over the world but also to extreme weather phenomena. The rise of the temperature can affect the Sea Surface Height (SSH) in more...

Direct Analysis on Point Clouds: Geomatics Syntesis Project 2019

With the rapid growth in point cloud acquisition technologies the recent years we have the ability to measure large quantities of 3D points of significantly detailed and geometrically composite scenes such as urban environments. This advantage can be exploited and used for direct analysis on point clouds. A direct point cloud analysis has...

A voxel-based methodology to detect (clustered) outliers in aerial lidar point clouds

To obtain 3D information of the Earth’s surface, airborne LiDAR technology<br/>is used to quickly capture high-precision measurements of the terrain.<br/>Unfortunately, laser scanning techniques are prone to producing outliers<br/>and noise (i.e. wrong measurements). Therefore, a pre-process of the point<br/>cloud is required to detect and...
