There isn't a function built into Filemaker to do this and Filemaker Go does not support plug-ins.
You might can integrate GISPro into filemaker using a webviewer. I don't use GISPro so I can't tell you for sure if this would work or how to make it work.
Hmmm, If you used the other App to manipulate the map, you might be able to capture that image and put it into a container field in FM GO. Don't know if that provides the needed functions for you or not though...
Brilliant... so simple. If nothing else, I could just do a screen capture. Its not perfect... but it would still be helpful in the field. Thanks.
