Hello,
I am investigating a lot in moving objects. I found out that in GML it
is possible to support that type of objects (gml:TimeSlice and
gml:MovingObjectStatus).
As an example I created a dynamic feature with following structure. I
strived for using as much standard elements from the GML specfication.
<?xml version="1.0" encoding="UTF-8"?>
<wfs:FeatureCollection>
<gml:boundedBy>
<gml:Envelope srsName="urn:EPSG:geographicCRS:4326">
<gml:lowerCorner>678351.04 50929.11</gml:lowerCorner>
<gml:upperCorner>679551.00 52000.31</gml:upperCorner>
</gml:Envelope>
</gml:boundedBy>
<gml:featureMember gml:id="0">
<MyDynamicFeature> <!-- corresponds GML DynamicFeature -->
<routeName>Linea10a</routeName>
<Trip id="1" line="l10a" up="true"> <!-- corresponds GML
dynamicProperties -->
<gml:track gml:id="1">
<gml:MovingObjectStatus gml:id="ts_0">
<gml:validTime>
<gml:TimeInstant>
<gml:timePosition>"2007-02-08T12:30"</gml:timePosition>
</gml:TimeInstant>
</gml:validTime>
<gml:location>
<gml:point srsName="urn:EPSG:geographicCRS:4326">
<gml:pos>678351.04 50929.11</gml:pos>
</gml:point>
</gml:location>
</gml:MovingObjectStatus>
<gml:MovingObjectStatus gml:id="ts_1">
<gml:validTime>
<gml:TimeInstant>
<gml:timePosition>"2007-02-08T12:30:52.33"</gml:timePosition>
</gml:TimeInstant>
</gml:validTime>
<gml:location>
<gml:point srsName="urn:EPSG:geographicCRS:4326">
<gml:pos>678888.08 50999.11</gml:pos>
</gml:point>
</gml:location>
</gml:MovingObjectStatus>
<gml:MovingObjectStatus gml:id="ts_2">
<gml:validTime>
<gml:TimeInstant>
<gml:timePosition>"2007-02-08-12:31:12.13"</gml:timePosition>
</gml:TimeInstant>
</gml:validTime>
<gml:location>
<gml:point srsName="urn:EPSG:geographicCRS:4326">
<gml:pos>67999.08 51999.11</gml:pos>
</gml:point>
</gml:location>
</gml:MovingObjectStatus>
</gml:track>
</Trip>
</MyDynamicFeature>
</gml:featureMember>
</wfs:FeatureCollection>
My question is, if UDig is capable to interpret such a WFS format. If
yes, please let me know, where to find the correct syntax for the XML
document.
thanks and best regards
Innerebner Markus
