[ka-Map-users] ka-map vs. ArcGIS

2600 points using Geo Objects will definitely have problems with most
browsers unless you dynamically create and remove them based on the pan and
zoom events.  

>From the example you include it looks like it is not nearly as dynamic as
geo objects are.  I would suggest you try using a map layer or layers with
queries or ajax requests to locate and display information on properties
within a small radius of the mouse click as geo objects or a special layer
for highlighting the selected properties.  

Based on my experience, I would say kaMap and mapserver could perform this
application with acceptable responsiveness.

Thanks, we're wondering specifically if there would be performance
differences in geocoding-intensive stuff like this:
I'm wonder if there would be performance differences on all those points for
foreclosed houses. This is in ArcGIS and I just haven't seen such an
intensive application in ka-map, but I'll try to reproduce this and see what
I'm not interested in the commercial services you pitched offlist. I hope I
can keep my e-mail address public without inviting more pitches for
consulting services.

	I'm not a former ArcGIS user, but I'd have to say that it all
	on what you need your solution to do.
	ka-Map, MapServer, MapGuide Open Source OpenLayers, MapBuilder, 
	etc ... are all very capable open source packages with healthy 
	communities, solid code bases, and a variety of consulting firms 
	willing and able to support you, but each one has particular 
	strengths and weaknesses.  None of them (arguably) could compete
	ArcGIS for breadth of functionality at this point in time, but 
	specific packages will do things better than ArcGIS.  And you have 
	the advantage of being able to talk directly with the developers,
	bugs fixed, get new functionality etc.
	Your best bet is to outline what functionality you need and we'll 
	point you in the right direction :)
	PS if you have the money to buy ArcGIS, you could spend it on
	trained in open source technologies or having a complete solution 
	developed for you by someone.
