How do I figure out the grid references necessary to create a circular 1 mile radius around one location?
Grid Reference: SO 47904 87484
X (Eastings): 347904
Y (Northings): 287484
I know the approach has something to do with referencing the number of degrees from the original point for instance 10. Then subtracting the output by the number of metres in the radius size (a mile, so 1609.344).
But I've forgot the actual approach. What is it, thanks?
