A radius is created when drawing a straight line from a central point to all possible points in a circle. Even if you were to substitute it with the radius of a sphere, assuming the Earth is spherical, at 3437.7468 NM, you will not be near the real, accurate distance. Rather than defining LONG_MILE as a constant, you should calculate it inside your GetRadius function: LONG_MILE = LAT_MILE / cos (OriginLatitude*PI/180.0) Also, it looks a little weird that you're taking sin () and cos () of your integer index i. If you have any problems or get unexpected results, please let me know! (The coordinates of the locations are provided by the Google Geocoding API.) If you don't supply units in the distance box itself (e.g., "100 mi"), it will default to kilometers. ), GPS Visualizer's coordinate calculators & distance tools, Calculate the great circle distance between two points, Calculate the great circle distance between two addresses, Draw range rings (concentric circles) around a point, Calculate coordinates at a given bearing and distance. Example: a GPS receiver having a 1.25 m DRMS error, will have a 1.25 × 1.73 = 2.16 m R95 radius. To calculate its position, a GPS device measures its distance (range) from multiple GPS satellites. Radius Map Calculator Draw a radius map. α max = l 60 / (π d) (4b) Bending PE Pipe Calculator. Some of those restrictions limit the movements of people to a certain maximum distance from their home.
