How to use the DEM v.1.1 (http://image.discomap.eea.europa.eu/[…]/)

Hi there,
how can I get the elevation value of a pixel from the new DEM, based on its RGB value? Green is low and red is high, but there is some weird gradient going trough.
Can someone share the exact formula?

Thanks

Dear vladimirt,

To be sure to get the right infromation you should use the WCS protocol and not WMS.

This service should provide you the underlying values.

If there is an error using these capabilities and our webservices please get back to us with a direct link to the requested service.

Kind regards,
