 106:32:29.490774E   39:53:38.049989N
 103:13:40.937174E   41:23:25.138711N
what's this coordinate.
How can I do if I want to traverse the entire map with this kind of
coordinate or some another suggestion？
The original plan was ready to use bash to get the value of the map
and then increase the latitude and longitude of the method, which
traverse the entire map data in the form I want, but this coordinate
format, I have not seen, how can I use, or do you hava better
traversal methods? thank you
