Time Encodings

There are four possible elements to use when encoding time in an XML SOS request: <gml:TimeInstant>, <gml:TimePeriod>, <swe:TimeInstantGrid>, and <swe:TimeIntervalGrid>.  These are described briefly below, with examples.  Note that in version 1.0 of the SOS Spec, <sos:time> has been changed back to <sos:eventTime>.   To validate these requests with the current OOSTethys schema trunk, you may need to change it to <sos:time>.

<gml:TimeInstant>

Used to request a single measurement at an instant in time. 

 <sos:eventTime>
    <ogc:T_During>
      <gml:TimeInstant>
        <gml:timePosition>2007-02-04T12:24:00</gml:timePosition>
      </gml:TimeInstant>
    </ogc:T_During>
  </sos:eventTime>

<gml:TimePeriod>

Used to request observations for a period of time.

 <sos:eventTime>
    <ogc:T_During>
      <gml:TimePeriod>
        <gml:beginPosition>2007-02-04T12:24:00</gml:beginPosition>
        <gml:endPosition>2007-02-04T15:24:00</gml:endPosition>
      </gml:TimePeriod>
    </ogc:T_During>
  </sos:eventTime>

<swe:TimeInstantGrid>

Used to request a set of uniformly spaced time instants

<swe:TimeIntervalGrid>

Used to request a set of uniformly spaced time intervals
