There's probably a term for this that I'm missing that would help me find the answer...

My question is similar to a previous question of mine. I am using GeoServer (as part of the OpenGeo stack) as a WFS server. Currently when I load my map it downloads the entire layer - roughly 10MB per layer, roughly 10 layers...it takes a while.

I would like it to work in the way that WMS does - only download enough to show what is needed.

I need to use WFS rather than WMS as I need to be able to click on polygons, edit their attributes etc.

Is there a word for this?

Is it possible with GeoServer/OpenGeo/GeoExt?

I think that's what OpenLayers BoundingBox strategy is good for.

A simple strategy that reads new features when the viewport invalidates some bounds.

If it's in OpenLayers, it should be available in GeoExt too.

  • Perfect! That's just what I was looking for and I only had to change one line of code! Only problem now is that it isn't obvious when it is loading data and when it is finished...any ideas? – Mr_Chimp Apr 28 '11 at 13:48
