I am trying to create a tool in the task pane where you click a button and

maps.  I have found the sample onpointdigitized php example and copied the
code and it works pretty well to get the x, y coordinates.  The next step is
that my map is in state plane california III (feet) projection, so the map
units (feet) do not correlate to google maps (WGS84, decimal degrees).  I

onpointdigitized).  I was wondering if anyone could provide some help.  It's

(I already got an API key).  

Any help would greatly be appreciated (I am more of a GIS user than
