Mapping

If you are using a projected coordinate system, finding a location from a bearing and a distance is easy πŸ—Ί

newX = startX + distance * sin(bearing/180*pi)

newY = startY + distance * cos(bearing/180*pi)

Distance is in map units, so if you are working in UTM then that’s meters.

Bearing is in compass degrees, due north is 0, due east is 90, etc.

Mapping observation

I always think it’s a bit weird that longitude is the x axis, while latitude is the y axis, even though we always write latitude-longitude or y axis, x axis. Doesn’t x become before y?
