Enter Coordinates:
LAT(-south,+north),
LONG(-west,+east)


|  |  |  |  |  |  |

Enter the coordinates of a location you wish to locate in 
DMS(degrees,minutes,seconds) format.  Not decimal DMS format! 
Enter coordinate on the same line separated by a space between latitude 
and longitude.

Valid coordinates for latitude are -90 00' 00'' to +90 00' 00'' and 
valid coordinates for longitude are -180 00' 00'' to +180 00' 00''.  

Press [ENTER] after you have entered a coordinate and search for a
