Re: [las_users] Lat/Lon problems

[Anton Yoel Buenavista <tmsbayd@xxxxxxxxxx>]

Hi Bastian,

Thank you for you advice. At the moment, I'm trying to add to your code 
to support 'seconds'. On the LASConfig.java, on your code for adding 
minutes, could you kindly explain what this line means?

minutes = (int) (12 * 8017 * 3);

How would like to know what the values 12, 8017, and 3 mean as well as 
how you came about with those values.

Regards,
Anton Yoel Buenavista
