GML Observations

Ever wanted to take a photograph and then record it along with the location and time at which it was taken? Ever wanted to post those on the web?

A GML Observation models the act or the doing of the observing. It is a GML feature.

It has the following properties:

If you can deal with a feature, you can deal with an Observation. You can use the concrete GML observation "out of the box" or create your own custom ones. There is even a concrete DirectedObservation which adds a direction of looking to the above properties.

Look at the notes on styling (see further down in this BLOG) to see how to put your observations on a map.
