IQmulus is a network of organisations interested in the processing of 'big data' point clouds such as datasets produced by Lidar, Sonar and Laser Mobile Mapping. Members range from ICT organisations developing the latest computing infrastructures, to research organisations developing the latest algorithms, and end users applying ideas to support reliable decision making. If you share any of these interests we would be pleased to hear from you!

IQmulus presented at EuroSDR workshop

On April 4, 2018 the IQmulus coordinator presented IQmulus and the Norwegian follow-up project ANALYST at the EuroSDR workshop Use of algorithms on big DEM's. The workshop took place in Tønsberg, Norway. The workshop attracted 30 participants from nine European countries. As the workshop was focused on LIDAR data, the results of IQmulus matched the topic of the workshop well.

Visualising Point Clouds and Surfaces on the IQmulus Project

Presentation: Visualising Point Clouds and Surfaces on the IQmulus Project

HR Wallingford Exchange Forum, Howbery Park,19th July 2017

The IQmulus project addressed the challenge of taking geospatial point cloud and coverage data and interpreting it with functions such as interpolation, feature detection and change detection so that it could be more easily used for decision-making tasks. One key aspect of HR Wallingford’s role on the project was to investigate processing and visualising bathymetry datasets using the SeaZone holdings of bathymetry surveys. The purpose of this presentation is to describe and, where possible, demonstrate key visualisation applications developed at HR Wallingford.
