Python : Generate Random Latitude and longitude


Take any Lat-Long Position across the globe.

Example
Center of NewYork,NY,USA
LATITUDE = 40.750422
LONGITUDE = -73.996328



Python code to generate 100 random Lat Long positions:


=====================================================================
import random
import sys
import math

outfile = open("output\randomLatLong_NY.txt", "w")

radius = 10000                         #Choose your own radius
radiusInDegrees=radius/111300            
r = radiusInDegrees
x0 = 40.84
y0 = -73.87

for i in range(1,100):                 #Choose number of Lat Long to be generated

  u = float(random.uniform(0.0,1.0))
  v = float(random.uniform(0.0,1.0))

  w = r * math.sqrt(u)
  t = 2 * math.pi * v
  x = w * math.cos(t) 
  y = w * math.sin(t)
  
  xLat  = x + x0
  yLong = y + y0
  outfile.write (str(xLat) + "," + str(yLong) + '\n')

=====================================================================
