Suggestion'.......To put it simply 1:50,000 Each square on the map is 2cm and this equals 1 kilometre/kilometer on the ground. so measure the distance on the map with a ruler and multiply by 2 to get the distance in kilometers. HTH Lyn brown in Griffith NSW PS a larger scale map will show more detail of the area.ie. 1:25,000 On 13/10/2008, at 4:03 PM, Scott R. C.
