This is a bit of a repost, but I'm hoping someone can help.

Using Excel 2016.

We have about 3500 geo points, each defined by its latitude/longitude. Each geo point resides in one and only one of about 60 geo areas. Each geo area is defined by the latitude/longitude of its "corners." A geo area may have up to 10 "corners." Corners are typically shared by adjacent geo areas. So, how to determine in which geo area each geo point resides?

I appreciate your help.
