Perform Spatial Classification Query

  • Query for WCS services
    • select classification node Web Coverage Service or enter the value

 /urn:x-ogc:specification:csw-ebrim:ClassificationScheme:ISO-19119:Services/2000/2300/OGC-WCS

If you have followed the other stages then there should be two service results

 ICEDSWCS
 MapServer WCS

Perform Spatial Query

  • Query by arbitrary polygon extents
    • select findByWKT from predefined queries
    • perform the search with the default polygon WKT

 SRID=4326;POLYGON(( -180 90, -180 -90, 180 -90, 180 90, -180 90))

This will return all the available coverages, note that the srtm coverage is specified twice since it is specified twice in the ICEDS WCS capabilities document.

  • Change the query for a smaller extents not covered by all the coverages.

 SRID=4326;POLYGON(( -180 10, -180 -10, -170 -10,-170  10, -180 10))

This will return the SRTM coverages from the MapServer WCS
