10.13 Requirements Class: Monitoring Point

This requirements class is to be used to describe monitoring points sampling points that are described using a point-based geometry. WaterML2.0 extends the OMXML Sampling Point type to add metadata specific to hydrological monitoring. Requirements Class http:www.opengis.netspecwaterml2.0reqxsd-monitoring-point Target Type Data instance Name Monitoring point Dependency http:www.opengis.netspecwaterml2.0requml-monitoring-point Dependency http:www.opengis.netspecwaterml2.0reqxsd-xml-rules Dependency http:www.opengis.netspecOMXML2.0reqsamplingPoint Requirement reqxsd-monitoring-pointvalid The content model of this element shall have a value that matches the content model defined by wml2:MonitoringPoint. The Deddington monitoring point samples the Nile river. The monitoring point is at latitude 41.814935S and longitude 147.568517W and uses the Australian height datum as a reference datum. The monitoring point is in the Australian Easten Daylight Timezone, 11 hours ahead of UTC. wml2:MonitoringPoint gml:id = xsd-monitoring-point.example gml:description Nile river at Deddington, South Esk catchment, Tasmania gml:description gml:name codeSpace = http:www.csiro.au Deddington gml:name sam:sampledFeature xlink:href = http:csiro.aufeaturesriversnile xlink:title = Nile River sams:shape gml:Point gml:id = location_deddington gml:pos srsName = urn:ogc:def:crs:EPSG::4326 -41.814935 147.568517 gml:pos gml:Point sams:shape wml2:verticalDatum xlink:href = urn:ogc:def:crs:EPSG::5711 xlink:title = Australian height datum wml2:timeZone wml2:TimeZone wml2:zoneOffset +11:00 wml2:zoneOffset wml2:zoneAbbreviation AEDT wml2:zoneAbbreviation wml2:TimeZone wml2:timeZone wml2:MonitoringPoint XML Example 7 - Monitoring point OGC WaterML 2.0 OGC 10-126r4 Copyright © 2012-2014 Open Geospatial Consortium 91

10.14 Requirements Class: Collection

This requirements class is to be used to describe collections of objects from WaterML2.0. This includes observations, sampling features, sampling feature groups and inline dictionaries. Requirements Class http:www.opengis.netspecwaterml2.0reqxsd-collection Target Type Data instance Name Collection Dependency http:www.opengis.netspecwaterml2.0requml-collection Dependency http:www.opengis.netspecwaterml2.0reqxsd-xml-rules Requirement reqxsd-collectionvalid The content model of this element shall have a value that matches the content model defined by wml2:Collection. See Annex B for an example collection.

10.14.1 Use of inline dictionaries

The localDictionary element allows dictionarycode items to be encoded within the collection. This allows local references to be made to the dictionary rather than external links via xlink. Examples of its use are provided in Annex B.
