I need to support bathymetry below 1000 meters for a project using cesium. Is there any plan to update the cesium terrain format to support that in the future?
If not, I would like to consider creating a provider to merge bathymetry (and possibly other localized terrain sets) with your terrain data locally rather than hosting an entire high resolution terrain set. Do you see any problem with this approach? Is multi-terrain set support something that in your near term road map?
