Rob Atkinson a écrit :
1) A coverage is a Feature describing the state ("range") of a spatially
distributed phenomenon In many (if not all!) is in fact some sort of
special case of an Observation Feature where the procedure is a remote
sensor, a chain of models or a sampling regime.
This is a very interresting comment, since also tend to see Coverage as
a kind of Observation :). Actually, we handle it that way in an internal
program in our laboratory. I have not yet offered the code to Geotools
mostly because I'm not yet sure what an observation should look like in
the Java world. Last time I looked, the OGC "Observation and
Measurement" discussion paper was still somewhat vague.
