Slides from my presentation to the State of the Maps Scotland conference a the Inspace Gallery in Edinburgh on Saturday 12th October. The presentation covers 3D building tags in OpenStreetMap, creating 3D models from open data, and how architects might incorporate OpenStreetMap in their practices and how they can give back to the open data movement in return. A video of the presentation can be found at http://www.youtube.com/watch?v=CklS1QkNT48

2. Introductions
I am Duncan Bain, a Glasgowbased architecture graduate
and current MPhil researcher at
the University of Edinburgh.
This presentation introduces
one of the projects that I
have recently taken part in;
the creation of community
developed
3D
building
information and open source
architectural model data, and
explores where this technology
might lead us to.

4. Overview of the Gorbals Project
A project, initiated by MAKLab
in Glasgow, to develop tools for
community assets mapping and
the creation of materials that
could be used by community
organisations and individuals
in development work.
An experiment in creating 3D
visualisations and architectural
models from open data.

12. Workflow
OSM Tags
building:height
Sets the buildings height from ground level to top of roof.
building:levels
Sets the number of stories and can be used to approximate
total height.
roof:height
Sets height from top of roof to the eaves
roof:shape
Sets generic roof configuration, including typical forms such
as gable, hipped, mansard etc.

16. Workflow
From OSM to OSM2World
Export .osm file of desired area from
JOSM or OSM website.
Open OSM2World and select “Open
OSM File”
Large filesizes and areas with highly
detailed buildings will take a while to
process

19. Workflow
OSM2World to 3D CAD Processing
Export data as .obj file
Import .obj file in to preferred CAD
programme (eg. Sketchup, Rhino)
Clean up glitches and excess data

20. Workflow
3D CAD processing

3D CAD processing

24. Workflow
Fabrication
From CAD package, file can be
exported for 3D printing
Increasing number of local 3D printing
and digital fabrication services
Online services like Shapeways deliver
in a range of materials

27. Where to take the technology?
Will this concept be expanded
to cover other areas?
Might every buildlng on OSM
one day have height and shape
data?
Could this data provide a tool
to create cheap and open tools
and materials for community
groups and designers seeking
to transform their local areas?

28. Where to take the technology?

29. How to get there?
Apple Maps and Google Earth
LIDAR and Photography

30. How to get there?
What tools currently exist
that offer potential routes of
exploration in developing this
technology?
How can we develop the data
required, and how can and
should that data be integrated
into OpenStreetMap?
How can both OpenStreetMap
and designers benefit from this
exploration?

39. How to get there?

40. How to get there?
Wikihouse/OpenDesk Model
Open data and local fabrication

41. How to get there?
How to streamline the process?
Can OS contour (or other 3D data) be
incorporated into OSM, or attached
as standalone service? Is this even
desirable?
How can building footprints work to
fit this 3D surface?
Need to develop a system similar
to export settings on OSM website Simple!

42. OpenStreetMap and Architects
How can architects and other
design professionals working
in the built environment
incorporate
OpenStreetMap
into their practices?
How might OpenStreetMap be
developed to better serve these
practices?
Where do architects fit in the
open knowledge and data
movement and how can they
contribute?

43. OpenStreetMap and Architects
OSM at an ‘architectural’ scale?
Will there ever be a demand for
accuracy to the scale of architectural
working drawings?
How to achieve accuracy at this scale
using existing OSM techniques?
Where to find and how to collect this
data?

44. OpenStreetMap and Architects
A student army of mappers!

45. OpenStreetMap and Architects
Architects and Open/Commons
INPUTS:
Geographical data, CADesign data
PROCESS (Tools):
CAD
packages,
Fabrication
technologies (models, components)
OUTPUTS: Improved accuracy of
geographical data, CADesign data,
Architecture?!
