The workflow provides quick solution for extracting flood/waterlogging information from multispectral remotely sensed images. The threshold-based thematic classification works primarily on top of atmosphere reflectance values and multiple spectral indices. You can run the workflow on TIFF or GeoTIFF images. Additionally to the image, original metadata has to be uploaded because of ToA-reflectance calculation. As a result, an uncompressed regular TIFF of GeoTIFF will be generated, containing thematic class numbers indicating the degree of flooding.
The best way to start your IQmulus experience is by clicking around the IQmulus Demo System (IQDS). This is a fully functional installation of the IQmulus System with sample data and predefined workflows, yet you are free to make modifications and run processes.
IQmulus has begun its Exploitation and Maintenance Period as of 1st November 2016.

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.
