[mapserver-users] WCS server not

[Jorge Lopez]

Hello;

I am newbie to Mapserver, so maybe this is a naive question but I am doing
my best to find a solution to serve raster data by using Mapserver.

I have MapServer 5.6.5, I have prepared my map server with WFS and WMS  and
I would like to serve GEOTIFF images with WCS 1.0.0 protocol.

I prepared a map file, with two layers to be served and I made a
capabilities of the server:

http://domainserver/cgi-bin/mapserv?SERVICE=WCS&VERSION=1.0.0&REQUEST=GetCapabilities

The problem is that all metadata is full but there is no content for
coverages ("identifiers" in v.1.1.0), that is, the content between
ContentMetada labels is empty,

<ContentMetadata>
</ContentMetadata></WCS_Capabilities>

So I don't know what is happen, I made a probe like using shp2img to
generate a image png from mapfile and it is done

My Mapfile (only one layer) looks like in the following way:


MAP

END #end map


I have no xml capabilities file if I set DUMP TRUE in LAYER class, there is
a internal server error according to Apache.

I don`t know if there is a problem with GDAL library or not. I am just be
confussed

Any help would be very appreciate.

Thank you in advance

Jorge
