[OpenLayers-Users] Reverse geocoding with Nominatim an OpenLayers

[Stephen Woodbridge]

Hi Hendrik,

I do not think there is a canned example of what you are asking.
The strategy for doing this would be to add a double click handler which 
would make an ajax request back to your server and your server would 
need to forward that request to the Nomination service, get the results 
and send it back to your ajax response handler. The response handler 
would then parse the results, create a pop-up and add the response 
content to the pop-up, and then add the pop-up to an appropriate layer. 
This implies that you have a layer specifically for add in the pop-up(s) to.

So break this down an look for examples that do:

1. double-click handlers
2. ajax request
3. framed-cloud pop-up

You will probably need to create a simple ajax handler on the server 
maybe a little PHP code.

Hope this helps,
   -Steve
