who has already worked with WCS?

# The Web Coverage Service is defined by the Open Geospatial Consortium (OGC) (2012): # # *

The OGC WCS supports electronic retrieval of geospatial data as 'coverages' -
that is, digital geospatial information representing space/time varying phenomena

* # #
# #

Therefore, WCS is a standard data -access protocol that defines and enables web-based retrieval of multi-dimensional geospatial datasets.

# # Let's picture WCS within in the common OGC web service suite... # #

Unlike Web Mapping Service (WMS), which returns spatial data as an image, WCS returns data in its raw form, with its original semantics.

* # #
# This allows for further web-based data processing or the building of web applications. # What about WC**P**S? # # *

A Web Coverage Processing Service (WCPS) is an extension supported by the WCS 2.0 core specification and can optionally be implemented by a WCS server.
