The Ordnance Survey doesn't even hold height data on all buildings in the UK. They've started a few isolated projects but nothing as a deliverable dataset yet.

The Ordnance Survey doesn't even hold height data on all buildings in the UK. They've started a few isolated projects but nothing as a deliverable dataset yet. I don't think there's a US equivalent despite your link to NYC Open Data.
You might want to look to Germany and CityGML. You might discover some town datasets that are complete in height and geometry detail.
If you happen on a LIDAR data source you've then got to tidy up against the buildings but you will run into errors caused by the time spent between the two data capture points. There's SRTM but i'm sure it'll be too coarse for your needs. I'm sure there's a replacement to SRTM but the name escapes me.
There's LandXplorer - now owned by Autodesk which will generate models from oblique aerial photogrammetry. There's also CityEngine that'll create fake cities based upon road networks.

- robhawkes 14y agoThanks for the reply Andy, appreciated. We're actually talking to Ordnance Survey atm so hopefully we can work something out. Building height data for the UK (that's available outside higher education) is a pain to get hold of so I'm hoping we can work something out. I'll definitely look into the CityGML stuff, it sounds great. LIDAR is certainly something we're keen to explore further. If anything, it'll get us a much more accurate estimation of height, at least better than an educated guess or via SRTM (which is way to low detail and can't be relied on for buildings). The CityEngine stuff is amazing. I've not actually played with it myself yet but I've been having a good look at it during my research. Would be cool to have a go on it at some point.
