I have been having a go at drawing a regular polygon, in this example a hexagon, on a map. Not a big one, only 400m radius. I am using the haversine (great circle) formula to generate the points of the polygon from a centre point of coordinates. The use of the haversine formula seems to be causing …

Seemed to have fixed it. An issue with order of precedence in one of the formulas y = sin θ ⋅ sin δ ⋅ cos φ1 x = cos δ − sin φ1 ⋅ sin φ2 λ2 = λ1 + atan2( y , x ) This [blocks (17)] should be this [blocks (18)] Hexagon at 100m [image] Hexagon at 2000m :slight_smile: [image] If you want …
