[OpenLayers-Users] Google Popup feature layers

[John Cole]

Rob,

  That too is easy, if you have a spatial database as your backend (PostGIS,
MsSqlSpatial, Oracle, DB2).  We are doing something very similar on our HUD
site.  Many of the result sets have a ‘view in map’ link that uses the
extents from the objects geometry to make a JavaScript call to re-center the
map.  If you follow that example, you should easily be able to duplicate the
google maps search results.

Thanks John - I'll be looking at that as soon as I get the time :o(

Next question - can anybody point me at an example that works like the
Google Maps search results?  You could search for 'estate agents' in
'London', and be presented with a list of estate agents on the left hand
side of the screen, and the popups on the map. 

I want to present a list of features listed in tabular form, and clicking on
the text navigates the map to the feature (popup).

Cheers

Rob

Rob,

  We are using a WFS server to provide the markers for our points.
HYPERLINK "http://hud.uai.com/hudpls/" \nhttp://hud.uai.com/hudpls/  this is
running from a spatial database backend and works very well.

Hi

I've been using the Google-esque Popups (they're great!) but I have a
question.

My popup layer has over 17000 points, and when loaded as a Text layer, this
means that there is a significant load on the browser.  Is there an
effective way of using the Google popups via some kind of spatial database,
so that the requests can be spatially filtered at the server side (by
database or geoserver or something) 

MTIA
