3D Visualisation of Integrated Data Sets
Nick Holden,Managing Director N.J.Holden Consultancy ltdTechnical Director GeoVizix LtdPartnered with John Pepper OceanWise.
• Developed the Environment Agency’s LIDAR and Bathymetric survey capabilities.
• i-G Peninsula project to commercialise 3D visualisation of environmental data for decision making and stake holder engagement.
• Set up own company to exploit visualisation potential.
How I got here
Why do we need to visualise data.
• We need to engage professionals and the public before they get board.
• Most data set are not used for the purpose they were collected.
• Most users are unaware of the scale/resolution and accuracy that the original data was collected.
• Most projects will be criticised for some form of operator bias. Who believes a Photo Montage.
• The most reliable QC device is the Mk1 brain when connected to the Mk1 eyeball.
What do we need for visualisations?
• Gold standard LIDAR, Bathymetry, models and aerial photography , GIS data and maps.
• The ability to seamlessly merge coastal topography with bathymetry.
• Ability to handle large data sets.
• We need to be able to project other GIS type data onto the 3D world.
• We need to Project model/planning models into the 3D world.
