I use Mapbox terrain RGB [1]. A good free alternative is Nextzen [2], but they do not generate tiles past zoom level 15 (Mapbox does it to 20) and there are some random elevation spikes that Mapbox has cleaned up. I'm looking forward to a LIDAR elevation tile set becoming available because it can be loaded into Shademap without any modification and hopefully display shade from trees.

Are there current plans for a lidar derived surface elevation tile from mapbox? Even the USGS 3DEP program only offers preprocessed DEMs (that is, DTMs). I can see generating that sort of thing at ~5-10m resolution on a global scale from satellite imagery / photogrammetry. A global or even regional DSM would be quite a product.

  Not that I'm aware of. Just speculation that people would pay for such a data set.

Interesting, thanks, I'll have a look at Mapbox terrain RGB. Will be interesting to see the resolution of a LIDAR tile set if Mapbox are going to have one, I've found that I could sometimes find low-resolution free data (5M / 10M etc), but that higher resolution 25cm/50cm/1M etc was often commercial and very expensive, but that gives much more accurate results in city areas. I'll have a look at Nextzen also.
