WCS - Web Coverage Service
| Operation | Description |
|---|---|
| GetCapabilities | Retrieves a list of the server’s data, as well as valid WCS operations and parameters |
| DescribeCoverage | Retrieves an XML document that fully describes the request coverages. |
| GetCoverage | Returns a coverage in a well known format. Like a WMS GetMap request, but with several extensions to support the retrieval of coverages. |
GetCapabilities
A WCS server responding to a GetCapabilities request returns metadata about the service, including supported operations and parameters, and a list of the available layers.

This request shows an XML file containing the WCS 2.0.1 GetCapabilities response (the following pictures contains the dem__gt30e020n40 layer related sub-section).
Understanding the capabilities response
| Tag name | Use |
|---|---|
| OperationsMetadata | Provides details about the service's available operations. |
| formatSupported | Located under the ServiceMetadata tag.Lists the supported formats. |
| Extension | Located under the ServiceMetadata tag.Lists all of the supported crs. |
| InterpolationMetadata | Located under the Extension tag.Lists all of the available interpolation methods available. |

DescribeCoverage
The purpose of the DescribeCoverage request is to additional information about a Coverage a client wants to query. It returns information about the crs, the metadata, the domain, the range and the formats it is available in. A client generally will need to issue a DescribeCoverage request before being sure it can make the proper GetCoverage request

Understanding the describe coverage response
Notice the tag boundedBy, it describes the geographic extent of the coverage, It includes the following attributes:
| Attribute name | Details | Example |
|---|---|---|
| srsName | Coverage SRS | http://www.opengis.net/def/crs/EPSG/0/4326 |
| axisLabels | Labels to use to describe the coverage axis | Lat Long |
| srsDimension | Dimension of points in the coverage | 2 |
GetCoverage
The GetCoverage operation requests the actual spatial data. It can retrieve subsets of coverages, and the result can be either the coverage itself or a reference to it. The most powerful thing about a GetCoverage request is its ability to subset domains (height and time) and ranges. It can also do resampling, encode in different data formats, and return the resulting file in different ways.
