Many thanks for the quick response. Now that you've shown me how to get that working, it seems obvious that coordinates are X, Y pairs and not Longitude and Latitude. I've been trying various ways to construct a Polygon with lat/lon vertices and use the same approach to get the distance between a Position (defined with a lat/lon) and the lat/lon Polygon. Is that possible? Or do I have to go through the process of projecting lat/lon pairs into Y/X pairs?
Thanks again
