Demonstration

The EOxServer demonstration is an instantiation of the autotest instance and is based on the Envisat MERIS sample data available here.

The configuration includes one DatasetSeries and one StitchedMosaic both combining the three available datasets:

  • DatasetSeries (EOId: MER_FRS_1P_reduced) containing the 3 MERIS sample datasets with all 15 radiance bands encoded as uint16 values
  • StitchedMosaic (CoverageId: mosaic_MER_FRS_1P_RGB_reduced) containing the 3 MERIS sample datasets reduced to RGB 8-bit

Note, the data has been reduced from 300m resolution to 3000m.

The demonstration tries to show the usage of all available EO-WCS request parameters.

Interesting parts of the repsonse:

  • Advertising EO-WCS:

    <ows:Profile>http://www.opengis.net/spec/WCS_application-profile_earth-observation/1.0/conf/eowcs</ows:Profile>
    
  • The additional EO-WCS operation:

    <ows:Operation name="DescribeEOCoverageSet">
        <ows:DCP>
            <ows:HTTP>
                <ows:Get xlink:href="http://eoxserver.org/demo_stable/ows?" xlink:type="simple"/>
                <ows:Post xlink:href="http://eoxserver.org/demo_stable/ows?" xlink:type="simple">
                    <ows:Constraint name="PostEncoding">
                        <ows:AllowedValues>
                            <ows:Value>XML</ows:Value>
                        </ows:AllowedValues>
                    </ows:Constraint>
                </ows:Post>
            </ows:HTTP>
        </ows:DCP>
    </ows:Operation>
    
  • The server will limit the number of CoverageDescription elements in DescribeEOCoverageSet responses:

    <ows:Constraint name="CountDefault">
        <ows:NoValues/>
        <ows:DefaultValue>100</ows:DefaultValue>
    </ows:Constraint>
    
  • There is a StitchedMosaic available:

    <wcs:CoverageSummary>
        <wcs:CoverageId>mosaic_MER_FRS_1P_RGB_reduced</wcs:CoverageId>
        <wcs:CoverageSubtype>RectifiedStitchedMosaic</wcs:CoverageSubtype>
    </wcs:CoverageSummary>
    
  • There is a DatasetSeries available:

    <wcseo:DatasetSeriesSummary>
        <ows:WGS84BoundingBox>
            <ows:LowerCorner>-3.43798100 32.26454100</ows:LowerCorner>
