I cleaned up the the encoded polyline macro we reviewed at the last user group meeting. Find the macro attached. The macro requires an ID field and an encoded text string as an input.
The macro essentially goes through the algorythm describe here - https://developers.google.com/maps/documentation/utilities/polylinealgorithm, only in reverse.
I built this with the help of a few blog posts I found online. Once I find them again I will link them here as well :)
I look forward to seeing everyone at the next user group meeting!
