    Calculate polygon area from latitude, longitude coordinates.


      Hi there,


      I'm relatively new to Filemaker. I've written a script to create a KML polygon file based on the work from Otto Muller found here.



      I would like to add the ability to calculate the polygon area (acres or hectares) based on my list of latitude, longitude coordinates that make up the boundary of the polygon. Does anyone have any advice how to do this? Script/ Custom Function?


      Any help would be most appreciated.
