[udig-devel] uDig "pre-filtering" for WFS layers...
|
Hello,
I am a software engineer in the geoscience community that has spent time
working with GeoServer and uDig, among other technologies, to find
interoperable and scalable ways of displaying map-based scientific data
to research scientists. My working group has created and deployed
proof-of-concept WMS/WFS services, which provide some very useful
functionality. I would like to find out more about the [possible]
existence of client features that would apply a filter when adding a WFS
layer (for example), so that only a subset of the layer is actually
loaded/rendered up front? We deal with datasets that are sometimes
quite large, and are particularly interested in finding a way to limit
the layer according to the properties it represents. Note that while
applying a filter after the layer has loaded is also a nice [currently
existing] feature, I'm wondering about applying the filter before it
loads, to limit which points load at all.
I have looked through the documentation and email archives, and have
found references to programming solutions (i.e. extending or modifying
the codebase). Does uDig have any plans to incorporate this kind of
functionality into a release candidate? Alternatively, if I've missed
this somewhere in the current app, could someone please point it out?
Thank you in advance for any help or insight here.
Regards,
Chris Stolte
