Curious how you generate the maps. OpenStreetMap turns out to have most golf course features mapped by volunteers, so it's possible to pull that data (see here for a fairly rudimentary example: https://github.com/npilk/hacker-yardage). But you may have a better source.

I see you mention looking for topographical data at a good resolution. I'll follow that with interest. There are US public datasets (IIRC) at more like 3m or 5m resolution... not bad but not really good enough for golf, especially greenside. I couldn't figure out how to pull that info programmatically in the past, though.

Overall this is super cool work, will be watching for more!
