[OpenLayers-Users] Changing Layers is doing some funny zooming

[Stephen Woodbridge]

Hi all,

I'm posting for a developer that is building an application based on 
OpenLayers. Unfortunately is not on a public IP. We have noticed a 
strange problem, that I am hoping will be a know issue.


We have a ka-map tile cache preloaded with tiles in a geographic 
projection. It works great with OpenLayers and the developer sends Kudos 
for the clarity of the OL code and design.

We have created a Google account and added it to the layer switcher tab 
so we can switch between ka-map tiles, Google maps and Google Satellite.

This works mostly ok! We can switch between the layers and we get tiles, 
  BUT if we switch between ka-map tiles and Google we zoom out on the 
switch. This does not happen if we switch between Google Maps and Google 
Satellite.

I'm thinking this is some artifact of the fact that Google does not use 
a geographic projection and ka-map does and that somehow we have not 
configured the layers with the appropriate information so the OL can 
adjust for these differences.

Anyone seen this before or know how to fix it?

Thanks,
   -Steve
