GEMStat Web Services

Web Feature Service (WFS)

The Web Feature Service provides spatial data and metadata for GEMS stations. Each layer in these web services represents stations belonging to a single country.

GetCapabilities

Returns all features.

http://www.gemstat.org/WS/stationByCountry.aspx?service=WFS&version=1.0.0&request=GetCapabilities

DescribeFeatureType

Returns the schema description of feature types for the selected country layer. (e.g. <country> = India)

http://www.gemstat.org/WS/stationByCountry.aspx?service=WFS&version=1.0.0&request=DescribeFeatureType&typename=<country>

GetFeature

Returns all the features (GEMS stations) in the selected country layer. (e.g. <country> = India)

http://www.gemstat.org/WS/stationByCountry.aspx?service=WFS&version=1.0.0&request=GetFeature&typename=<country>

ParametersForCountry

Returns a list of parameters (abbreviated name, full name and units) that have data in a specified country. (e.g. <country> = India)

http://www.gemstat.org/WS/ws.asmx/ParametersForCountry?country=<country>

ParametersForStation

Returns a list of parameters that have data in a specified station.(e.g. <stationID> = 031001)

http://www.gemstat.org/WS/ws.asmx/ParametersForStation?station=<stationID>

Parameter web services support the SOAP protocol. The Web Services Description Language document can be found at:

http://www.gemstat.org/WS/ws.asmx?WSDL

Annual Averages

Returns annual averages for specified parameters (listed by abbreviated name) by country, by station in a selected country layer. Variables are separated by a semi-colon (;). (e.g <country> = India, <parameter> = Alk Total;NH3)

http://www.gemstat.org/WS/StationByCountry.aspx?service=WFS&version=1.0.0&request=GetFeature&typename=<country>&parameter=<parameter1;parameter2>

Monthly Averages

Returns monthly averages for specified parameters (abbreviated name) by country, by station in a selected country layer. (e.g <country> = India, <parameter> = Alk Total;NH3)

http://www.gemstat.org/WS/StationByCountry.aspx?service=WFS&version=1.0.0&request=GetFeature&typename=<country>&parameter=<parameter1;parameter2>&freq=month

Web Map Service (WMS)

The Web Map Service provides images for GEMS stations. Each layer in these web services represents stations belonging to a single country.

GetCapabilities

Returns all features.

http://www.gemstat.org/WS/stationByCountry.aspx?service=WMS&version=1.0.0&request=GetCapabilities

GetMap

Returns a map image of all GEMS stations. (gif, png, jpeg, wbmp and tiff) e.g. <layers> = all_stations

http://www.gemstat.org/WS/stationByCountry.aspx?service=WMS&version=1.0.0&request=GetMap&layers=all_stations&format=image/<type>

Returns a map image of India stations.

http://www.gemstat.org/WS/stationByCountry.aspx?service=WMS&version=1.0.0&request=GetMap&layers=India&format=image/gif

GetFeatureInfo

Returns information about the feature on the layer and is near to the location specified. (e.g. <X> = 182 and <Y> = 73)

http://www.gemstat.org/WS/stationByCountry.aspx?service=WMS&version=1.0.0&request=GetFeatureInfo&layers=all_stations&query_layers=all_stations&<X>=##&<Y>=##&info_format=application/vnd.ogc.gml

DescribeLayer

Returns a description for the country layer. This data allows the request for more information using the associated WFS. (e.g. <country> = India)

http://www.gemstat.org/WS/stationByCountry.aspx?service=WMS&version=1.0.0&request=DescribeLayer&layers=<country>

GetLegendGraphic

Returns an image of the legend for the country layer. (e.g. image <type> = gif, <country> = India)

http://www.gemstat.org/WS/stationByCountry.aspx?service=WMS&version=1.0.0&request=GetLegendGraphic&format=image/<type>&layer=<country>

GetStyles

Returns a description of the style (in SLD format) used to draw the country layer. (e.g. <country> = India)

http://www.gemstat.org/WS/stationByCountry.aspx?service=WMS&version=1.0.0&request=GetStyles&layers=<country>

Google Earth and Google Maps Web Services

Web services have been developed to output the GEMS stations in KML 2.0 format so that the stations for one or more countries can be displayed in Google Earth or in Google Maps.

StationKML

Returns the GEMS station locations for the requested countries in KML format. Results can be saved to a file with a kml extension and later opened in Google Earth. [Screen shots from Google Earth v4.1.7087.5048]. (e.g.<country> = India, <format> = GE (or GM))

http://www.gemstat.org/WS/ws.asmx/StationKML?country=<country>&format=<format>

For multiple countries, replace <country> with a comma-separated list of the country names (e.g.<country> = India,China <format> = GE (or GM)). The name must be on of the layer names returned by GetCapabilites request in Web Feature Service.

http://www.gemstat.org/WS/ws.asmx/StationKML?country=<country,country>&format=<format>

StationKMLLink

Uses the Network Link method of obtaining the station data within Google Earth. The network link method is very useful when dynamic data are involved as the link can be refreshed and provide the latest data on the map. [Screen shots from Google Earth v4.1.7087.5048]. (e.g. <country> = India, <format> = GE (or GM))

http://www.gemstat.org/WS/ws.asmx/StationKMLLink?country=<country>&format=<format>

When a station is activated general information is shown. Clicking on the View summary data at GEMStat web link at the bottom of the station information box will open the GEMStat web site in a browser listing parameters available for analysis. Select a parameters and view the summary data and graphs for the highlighted station.

http://www.gemstat.org/WS/ws.asmx/StationKMLLink?country=<country,country>&format=<format>

Google Maps

Displays GEMS stations in Google Maps. Type the URL for the StationKML web service, using the “GM” format, in the Serach text box at http://maps.google.com. Click on Search Maps. The “GE” format uses a custom icon for displaying the stations and has the stations hierarchically organized by country. (e.g. <country> = India and <format> = GM).

http://www.gemstat.org/WS/ws.asmx/StationKML?country=<country>&format=<format>

http://www.gemstat.org/WS/ws.asmx/StationKML?country=<country,country>&format=<format>

Google Earth and Google Maps web services also support the SOAP protocol. The Web Services Description Language document can be found at:
