If anyone knows any 'working' examples let me know. Tim IFM Can I also add we are in the same boat with WTS (Web Terrain Server), we can serve it with a tick box option in Cadcorp GeognoSIS.NET but I have yet to find a client in which to view it ?

If anyone knows any ‘working’ examples let me know.

Cadcorp SIS offers a free OGC desktop client (Map Browser) as well as full support in all desktop and server products and has a growing presence in Australia, especially in WA where it is used in a fair few State depts although sometimes re-badged as other solutions? Would be happy to carry out some testing both server and client if you have any good services - data Tim IFM Well, have you not answered your own question ?

I added link back to terrainserver in the img title. Let me know if this is not appropriate Dale: I hear ya on both fronts ... see reference to chicken meeting the egg :) Perhaps i should put my money where my mouth is. Build the bridge and see what happens.. id still like to hear from any group that actively uses wcs and under what circumstances though Cheers for comments guys Paul: u have a good memory!

Who wants to write one? :) To Dale: DeeGree is the reference implementation of WCS 1.0. GeoServer will shortly be the WCS 1.1 reference implemnetation (and implements WCS 1.0 already from Gs 1.5.0 onwards). MapServer can talk WCS 1.0 as well afaik. To everybody: What strikes me is that once again OGC people had to make a complex protocol for data extraction, in some ways, more complex than WFS is. But what's worse, you're going to have troubles if what you want to do is more than a mere data extractor... WCS server can support one of five specified data formats, what if you understand only GeoTiff and the server can only return NetCDF? At least with WFS we have, ugly as it may be, one guaranteed way to get a response (GML). That's the only format every client needs to understand. To Chris:

So can I ask the question -- where are the WCS servers? Is there a nice list of them somewhere (granted, my info on this is a year old now, but honestly at the time we couldn't scare up any publicly accessible ones to test against). So give us some servers, and hey, we'll get you at least one other client app.... Dale Hi,

It's sort of freaky, that picture is one we generated some years ago with our <a href="http://www.refractions.net/terrainserver/" rel="nofollow">TerrainServer</a> product (pre-Google Earth no-tech 3D). And in an eerie coincidence, TerrainServer can in fact act as a WCS client, to fetch the underlying DEM for the models it builds. What led you to that particular DEM picture, Chris?
