Hello,
by setting up a WFS server i need to limit the time interval for the requests
to the postgis db (Millions of data points inside POSTGIS).
The WMS part with time interval requests is working and i'am trying to make
these data available through WFS as well.
What i can find in the docs is a FILTER with a WFS Client connecting a WFS
server.
But this seems not to apply for DATE interval calculus.
The only thing i get in the moment is the whole data set at once or the first
NUMBER (here 10) of entries.
Is it possible at all to limit the requested time interval to a WFS server ?
i.e. something like TIME=2007-1-2/2007-1-3
Hi there,
There is no explicit support of a TIME parameter in wfs but I believe
It should be possible on a postgis layer to use the FilterEncoding to
limit the request: would something like this work for you:
Filter=<Filter><And><PropertyIsGreaterThan><PropertyName>your_time_field</PropertyName><Literal>2007-01-02</Literal></PropertyIsGreaterThan><PropertyIsLessThan><PropertyName>your_time_field</PropertyName><Literal>2007-01-03</Literal></PropertyIsLessThan></And></Filter>
regards,
Thanks and Regards
Heiko
