OSM file for Elk

[wim (Wim Dekeyser)]

Hi -

@clonosis

In either Gismo or Elk (currently trying Gismo but getting errors), how would I get a 3d model/extrusion of a building then?

Djordje answer that question for Gismo. If the height is provided, it is used. If that is not available, but the number of floors is available, the component will multiply that with a value that you can specify. If neither is available, the component looks at the range that you provide.

Elk doesn’t have a component that does all that for you but you can check which information is available in the osm file for each building and then apply the logic yourself. Tim Stark has provided a graph that does all that:

Boston OSM Heights

Not the best example, because there is much randomness, but the first one I found on my Computer. [elk_city] As you can see, some numbers have a m in the end. So I needed to remove them. [elk_city_1] Or one Building, had also underground levels. Didn’t needed them, so I removed it. [elk_city_2] And the Buildings where I hadn’t any height, were extruded by random numbers. You can choose the Domain, so it fits to the existing ones. But you Need nearly always to search the text for Errors…
