[ka-Map-users] Problem with extent in kamap demo little changed

Marco,

the array that is the third parameter in the config file is an array  
of scale values, not an array of extents.  ka-Map only uses the  
extents from the map file.

The scale values should all be positive and from largest number to  
smallest number as in the example.

You will probably want to start around 5000000 and go down from there.

The inchesPerUnit array in init.php is used to convert a scale value  
to some geographic extents when the init.php script is called with a  
center point and scale rather than extents or nothing (which results  
in the default extents).

Cheers

Paul
