RealUrban3D London data, OS OpenData & OpenStreetMap data playing nice in ArcScene & CityEngine

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?


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….

Modelling an Historic Arab City Centre in 3D using CityEngine – Continued

Okay, I keep coming back to this rule file tweaking various elements, this time I’ve added wind towers to it.   Wind towers aren’t a feature of every old Arabic urban area (that’s why I’ve included a switch to turn them on and off), but it felt wrong not to include them…

There’s still room for improvement, every so often I get features hanging in mid-air, probably because of some of the odd shapes.   The images below have are just taken straight from a webscene (no other rendering or enhancements).   This time the shapes the buildings are built on are real world plots from a job we’re working on (believe it or not this is work here for a real planning job!).

Some people may recognise my favourite water tower and TV mast from previous models… there are too many mosques here as well.
I want to next work on the utility networks, these poles are far to neat…
You can see my parking garage there….
