  • this question is pretty vague, what did you try to solve the problem? is it even computer science related? what technologie are you using? – Ali BAGHO Aug 10 '17 at 10:28
  • I need to use real time gps for my application. Application is basically related with V2X technology. – Sukanya Aug 16 '17 at 11:06

here are some approximative conversions

  • Latitude: 1 deg = 110.574 km
  • Longitude: 1 deg = 111.320*cos(latitude) km

to answer your question :

  • 4 meters east/west = 0.00003617486 deg latitude
  • 4 meters north/south = 0.00003593244 * cos(latitude) deg longitude

remember to convert the latitude using this radians = degrees * PI / 180 before using the cos

note : the numbers probably need more complicated equations as earth is not perfectly round
