CALL FOR IDEAS || Irregularly-Shaped Boundary Recognition

[MultiTech]

Hey all you AppSheet-hackers out there, I need help figuring out a solution for recognizing if a user’s reported location is inside an irregularly-shaped boundary. Creating a “box boundary” is easy (with a mix/max of the lat/long), but finding a way for irregular shapes to be included as well - that’s another task.

Ray casting

Ray casting is the use of ray–surface intersection tests to solve a variety of problems in 3D computer graphics and computational geometry. The term was first used in computer graphics in a 1982 paper by Scott Roth to describe a method for rendering constructive solid geometry models. Ray casting can refer to a variety of problems and techniques: Although "ray casting" and "ray tracing" were often used interchangeably in early 3D computer graphics literature, more recent usage tries to distingu...

Good luck!

Any update on this? 

I'm donating an app to several charitable organizations and we need a way to redirect the user to the correct organization based on an irregular geofence/polygon.
