ArcMap_OSOpendataRoads_OpenStreetMapBuilding_RealUrban3DLondonOkay I can tell you hate the overly wordy title, but there you go, I like to mix things up a bit, but I think I may have gone to far here.

  1. RealUrban3D London model
  2. OS OpenData for streets centre lines
  3. OpenStreetMap building footprints
  4. Analysis in ArcScene
  5. Visualisations and webscene production in CityEngine (to be fair I could do the webscene export in ArcScene with the new toolbox)

Why?  because I can.  Okay, there is a serious point here and that is data and GIS are a messy chaotic business (they shouldn’t be but they are).   We don’t get things in neat formats always and just because you can’t see a reason why I’m using OpenStreetMap and OS OpenData together that doesn’t mean there isn’t a reason.

Up close, see it fits! It fits! Hurrah!

After combining the data CityEngine handles the various elements, here I’m using the centre lines for creating roads (graph networks in CityEngine).  Then I’ve put the resulting model back into ArcScene for some flashy but ultimately not that useful ‘line of sight’ and ‘skyline’ tools.

Skyline Barrier created in ArcScene, visualised via CityEngine export to webscene (looks pretty but what is it telling us?

 

arcscene_visibility_from_proposed_tower_block2
Each window in the awful (but CityEngine generated) tower block has been made a viewpoint and the Skyline analysis was run…

 

You may have noticed my fascination with CyberCity3D/RealUrban3D data, well I’ve got a post about that coming, but basically I’m advising them in a consultant capacity….
