CryoLand - The GMES Service for Snow and Land Ice

Logo of the CryoLand Project

This is the Online Data Access Services Demonstration Activity of the EC-FP7 CryoLand Project.


Available Online Data Access points:

 
  • Interactive Map-Tool   (Optimized for Firefox & Chromium;  IE has problems with style and only donwloads the first file of a selected time-series, instead all files).
  •  
  • Examples of HTTP-KVP requests
  •  

    Available Services:

    The CryoLand Project provides Online Data Access to the CryoLand Snow and Land-Ice Products based on OGC standard interfaces. Beside the Online Data Access via the Interactive Map-Tool the following OGC standard interfaces are provided:

    Support has changed to EO-WMS and EO-WCS (WCS 2.0) only!

     
  • EO-WMS ( Web Map Service + EO Application Profile )
  •  
  • WCS ( Web Coverage Service )
  •  
  • EO-WCS ( Web Coverage Service + EO Application Profile )
  • Due to the large number of datasets offered by CryoLand, baseline WMS requests are not supported anymore, since e.g. a WMS-GetCapabilities Response exceeds any reasonable size (>16MB) and creation time (~20min) for the offered products (~20.000 products). This change, to support only EO-WMS & EO-WCS, implies that only DatasetSeries (often called Collections) are now listed in the GetCapabilities response.

    Below you find some example requests, and their syntax, to access the various service interfaces available. Such request may be issued with any Webrowser or other tool able to send HTTP GET requests (e.g. wget, curl, etc.) or from within GIS-Tools (e.g.QGis, etc.).
    More examples and further explanations as well as additional parameters and refinement methods available with WCS/EO-WCS can be found in EOxServer's Documentation ( [ Demonstration ], [ Parameters ] ).
    General information about the applied OGC standards, as well as the standards documents are provided by OGC.

    Example requests:

     
  • EO-WMS
  •    
  • GetCapabilities:

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WMS&Request=GetCapabilities


  •    
  • GetMap - DatasetSeries and Time:

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WMS&Version=1.3.0&Request=GetMap&Layers=daily_FSC_Baltic_Optical&CRS=EPSG:4326&Width=540&Height=200&Format=image/png&Transparent=true&BBOX=60.0,15.0,70.0,42.0&TIME=2012-03-31T10:07:00Z/2012-04-01T10:15:00Z


  •    
  • GetMap - you may use a direct request if you already know the exact product name e.g. from a prior WCS DescribeEOCoverageSet request:

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WMS&Version=1.3.0&Request=GetMap&layers=FSC_0.005deg_201203070926_MOD_Baltic_SYKE.tif&CRS=EPSG:4326&Width=450&Height=420&Format=image/png&Transparent=true&BBOX=42.0,15.0,60.0,42.0

  • EO-WCS ⁄ WCS
  •    
  • GetCapabilities:

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WCS&Request=GetCapabilities


  •    
  • DescribeEOCoverageSet - DatasetSeries ( e.g. Time Series ):

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WCS&Version=2.0.1&Request=DescribeEOCoverageSet&EOID=daily_FSC_PanEuropean_Optical


  •    
  • DescribeEOCoverageSet - DatasetSeries ( e.g. Time Series ) - a Slice subset in Time:

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WCS&Version=2.0.1&Request=DescribeEOCoverageSet&EOID=daily_FSC_PanEuropean_Optical&subset=phenomenonTime("2012-03-14T09:00","2012-03-14T09:00")


  •    
  • DescribeEOCoverageSet - DatasetSeries ( e.g. Time Series ) - a Slice subset in Time → no hit, therefore providing only the DatasetSeries description:

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WCS&Version=2.0.1&Request=DescribeEOCoverageSet&EOID=daily_FSC_PanEuropean_Optical&subset=phenomenonTime("2012-03-14T05:00","2012-03-14T05:00")


  •    
  • DescribeEOCoverageSet - DatasetSeries ( e.g. Time Series ) - a Trim ( Period ) subset in Time:

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WCS&Version=2.0.1&Request=DescribeEOCoverageSet&EOID=daily_FSC_PanEuropean_Optical&subset=phenomenonTime("2012-03-17","2012-03-19T12:00:00Z")


  •    
  • DescribeEOCoverageSet - DatasetSeries ( e.g. Time Series ) - a Trim ( Period ) subset in Time and spatial subset in Lat and Long:

    http://neso.cryoland.enveo.at/cryoland/ows?Service=WCS&Version=2.0.1&Request=DescribeEOCoverageSet&EOID=daily_FSC_PanEuropean_Optical&subset=phenomenonTime("2012-03-17","2012-03-19T12:00:00Z")&subset=lat(32,44)&subset=long(11,33)

    Note: After such DescribeEOCoverageSet Request an User's Application may parse the results and use the returned CoverageIDs to issue one or more GetCoverage Requests to access the datasets.
