Hey Bernard, Ah yes the Math4D component. I had forgotten about that! I’ll take a look.
If I add a field and split the longitude into degrees I’d likely use a long. I think that would give me the most flexible approach. Then searching for specific values like 115 or -47 would be easy. Creating a compound search with longitude degree and Country and I’m able to find the Olson timecode. And I think it might make the distance searching easier.
