[OpenLayers-Users] How to use WCS with OpenLayers

[Robert Buckley]

Hi,

Thanks for your helpful reply.

I have been serving a DEM through wms....but was trying to try it with wcs...basically just as a learning excercise really.

The DEM works as the value = height..and so getFeatureInfo displays the attribute....but I was curious. If the wcs protocol is not available for web clients....which desktop clients use it?  I don´t think QGIS has this capability.

yours,

Rob

Hi Robert,

You probably won't find any thin (browser) clients for displaying WCS data directly. There is such a sing as a Coverage Portrayal Service, which can make WCS data available through the WMS interface. However, GeoServer doesn't support it yet and as far as I know neither does anything else!

GeoServer makes coverages also available through WMS by default too. Couldn't you just display your data this way?  Or do you need to access some of the more advanced functionality of WCS?

Jon

Thanks.....that is all I wanted to know....that OpenLayers does not support wcs...but are there any api mapping libraries/thin clients or Hard clients (apart from ESRI)  available?
