Can be defined bbox parameter in a WCS service? I require trimming the layer coordinate in a box, I'm trying to prove the following WCS, but shows the entire layer globally:

http://geobrain.laits.gmu.edu/cgi-bin/gbwcs-dem?bbox=-76.70429,7.26988,-74.59818,9.56054&crs=epsg:4326

regards,

Samuel Mesa.

You don't say in your question what version of WCS is the highest supported by the service.

If for example the WCS service supports version 2.0.0 (or higher) then a BBOX request like this will not work (if you don't specify the version in the request you get the highest version supported). Instead you will need to using a trim sub-setting operation. The request would look something like:

http://[your-service]?service=WCS&request=GetCoverage&CoverageId=[your-id]&subset=x(76.70429,-74.59818)&subset=y(7.26988,9.56054)&
