Re: [Geoserver-users] Elevation WMS
Hi, I appreciate this is an old thread, however I wanted to follow up on this topic. Scaling some data across 65635 values (plus one assigned to missing data) and represented as 16-bit grayscale png image reachable via WMS would be quite useful; Yes, digital elevation models are an obvious use case. No need to consider this as "raw data".

Re: [Geoserver-users] Elevation WMS
Hi Andrea, Can you provide more details on how to get GeoServer to deliver a 16bit GeoTIFF? I've tried using both WMS and WCS services, but I keep getting an 8 bit format returned from GeoServer. My data store is 16 bit elevation data. Can you help with this? FYI, we'd really like to use GeoServer, but we really need to get the 16 bit data out in order to continue working with GeoServer.

Re: [Geoserver-users] Elevation WMS
Most elevation data you can paint to 16-bit without much loss of fidelity, depending on your range of values. For (the very flat) Ohio terrain we have, the range of values is from ~500ft to ~1500ft, so over a range of 1000 ft, we can paint values from 0-65535, meaning our precision is about 0.015 feet, which is more than adequate. We've had some use cases where our tool of choice could only handle 16-bit data, so it made sense to do the translation. Your client software would need to know how to translate that range back into your real range, I would guess. It might be simpler to just use WCS as Andrea suggests.
