4.3.4 SOS operations 4.3.4.1 Introduction
This clause discusses the features of the NRCan profile by using example SOS requests, encoded using both KVP and XML.
4.3.4.2 GetCapabilities
The following request causes a compliant SOS to generate service metadata in the form of an OGC capabilities document:
http:ngwd-bdnes.cits.nrcan.gc.ca:8080proxyGinServicesosgw?REQUEST=GetCapabilitiesSERVICE=SOSVERSION=2.0.0
The salient portion of the response is presented here and illustrates the profile directives that a SOS compliant with the NRCan profile would include in its capabilities document:
ows:Profilehttp:www.opengis.netspecSOS2.0confgfoiows:Profile -- TODO: add KVP BBOX profile when implemented --
-- Observation can be queries using spatial geometry expressed in param --pre ows:Profilehttp:www.opengis.netspecSOS2.0confspatialFilteringProfileows:Profil

4.3.4.3 DescribeSensor
The following two examples encode the same DescribeSensor request -- one using the KVP encoding and the other using the XML encoding.
