<p>Hi,</p>
<p>I use a combination of server code and Javascript.</p>
<p>I convert the lat long values to a javascript array which is loaded into a 2 dimensional array. This data is then loaded with the map which is quick if your polygons are not too complicated.</p>
<p>I then have a mouse over ont he map which checks as the mouse moves to see if is within the polygon. Since I am already creating lat/long values from the mouse over I just need to do a simple point in polygon check and I am there.</p>
<p>The other way I have thought is to create a html map using the polygon values that come back but I haven't done that.</p>
<p>To display the tooltip I use js_graphics (http://www.walterzorn.com/) library of tools which I find fantastic.</p>
<p>Cheers,</p>
<p>Simon</p>
