add from_open_street_map() Methods to Model Class

[AntoineDao]

Open Street Map is a strongly formatted and rich data format to host building information. I reckon adding this as a method might be a bit of a stretch as it would involve writing an XML parser for OSM etc... But might as well drop the issue here in case it gains traction.

This is a good idea. I would just note a few things: Getting openstreetmap solids into building typologies might involve some math that is pretty hard to do. Doing intersections of solids with planes is a pretty tough and it's something that I plan on relying on Rhino for for current building solids workflows. I think openstreetmap also has polygon information, which would be a lot easier to process (just like geojson).

One thing I would also note is that, if we add a method for this, we should write out from_open_street_map() because this can get very confusing with the .osm file type that is used to represent OpenStudio models.

Ah my thinking was to use the following information from Open Street Map:

• footprint geometry
• building height
• building type
• building age

The idea was that OSM is a strongly typed semantic map (more so than GeoJson which can hold the same information but name of the key values is likely to vary more).

Agreed about using from_open_street_map()! Ideally this method would also be able to do it using just latitude and longitude to download osm data from a fixed server.

Is this something you reckon I can start working on or should I put it on hold like the from_geojson() stuff?
