Textured LiDAR Scan of London: 1.5 Billion Points

Tweet

The movie below provides a quick glimpse of our latest dataset in CASA - a LiDAR scan of London within the M25 ring road, the model is made up of in excess of 1.5 billion points:

The points have been converted to a surface, texture mapped with aerial imagery and visualised in LandXplorer by Autodesk. A non textured mapped version can be seen below:

Thanks go to Duncan Smith at CASA for doing the processing and Cities Revealed for the data supplied by Landmap.

Note - the movie is slightly lower quality than our normal output here at digital urban as our Mac has been nicked, normal service should return next week...

LiDAR Scan of London in LandXplorer

The movie below details a 1 meter resolution scan of London using LiDAR (an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target via laser pulses, Wiki). The ability to load in the entire scan of London - some 1,500 kmsq - is thanks to LandXplorer by Autodesk and we are impressed:

Autodesk LandXplorer offers a collection of functions to interactively compose, present, explore, analyze, and edit geodata-based 3D models. In a sense, they represent a content management system for 2D and 3D geoinformation, which supports the effective handling of geodata assets.

Take a look at http://www.3dgeo.de/products.aspx for more info, we will have more on the LiDAR scan of London in future posts.
