SeedCode’s ProMaps lets you add your own links to Google Maps: users can click on a pin and run your own FileMaker scripts–going to that pin’s record in your FileMaker layout, for example.
While ProMaps could always do this for hosted files, FileMaker’s 13v2 update now lets scripts like these run locally, not just when your FileMaker file is hosted. Learn more and download a ProMaps demo to see how this works.
Purchased versions of ProMaps let you paste the map into your own FileMaker file and show your own records as pins on the map. Folks who are already using ProMaps can update to the latest version by changing a few scripts in their file: instructions here.
