Hi,
@lor74cas
Elevation data for routing: we have altered brouter internals to use our company maintained dataset, which combines enhanced SRTM source (viewfinderpanorama) and some Lidar sources. However the resolution is 3'' only.
I therefore suggest you to update the data with the more detailed ones at 1 "where available. Your servers will not suffer from a few more gigs of space occupied and a few more seconds of CPU usage, but you will give a more accurate data to everyone.
In my experience of use, 3 "is sufficient for road use (car, bike), but in the mountains 1" is better if, for example, you walk on the edge of a mountain ridge.
After all, the app allows the use of 1 "srtm (for the user it is only a matter of space occupied) on the cloud / web instead we should always have the best option.
