Dissecting a WCS Query

Address, port and provider

Identifying service, version and request


Identifying the coverage. Multiple coverages are not allowed.


Restricting boundingbox. Longitude range is -100..-90 and latitude range is 30..40


Selecting time. from 2008-07-02 to 2008-07-08 every three days: 2008-07-02, 2008-07-05, 2008-07-08


Selecting field SO4f only.


Want text/csv


Store the CSV file into the server and return only XML envelope with a pointer to it.


Live Query: VIEWS Map slice for SO4f



the service returns both XML Envelope and the CSV table in one [1] document. Unfortunately, all the browsers cannot handle it, firefox being tested as the only working client.

Live Query: VIEWS Map slice for SO4f with store=false

Filtering by Location Dimension loc_code

RangeSubset=SO4f[location[YOSE1]] selects field SO4f filtering by dimension location by loc_code=YOSE1.

Live Query: VIEWS Map slice for SO4f[location[YOSE1;GRSM1]]


Timeseries for one location. RangeSubset both selects fields and filters them by dimensions.

RangeSubset=BEXT[location[13935]] selects field BEXT filtering by dimension location by loc_code=13935.

The parameter store=true makes the return to be an xml document containing some meta information and a url to the CSV result. You need to copy the url from the XML envelope and paste it to address bar to retrieve it yourself.[location[13935]]&TimeSequence=2010-05-01T00:00:00Z/2010-06-20T00:00:00Z/PT1M

Same query, but The parameter store=false returns both the XML envelope and the CSV file in the same request.

So far only Mozilla Firefox can open it automatically. Internet Explorer, Safari and Chrome are not recommended here.[location[13935]]&TimeSequence=2010-05-01T00:00:00Z/2010-06-20T00:00:00Z/PT1M
