Thanks @tobias74!

We're generally happy to add support for different formats, assuming there is enough demand to justify the maintenance. We would love to hear from the community if there is interest! Maybe it would be worth asking on the community forum as well to reach a wider audience.

+1 on this! It looks like this AWS dataset uses Terrarium tile format. It'd be cool to support these RGB-encoded terrain formats like Terrarium and Mapbox's Terrain-RGB, as they're quite commonly used.
