decodeLatLon

public static double decodeLatLon(java.lang.String latlon)

This method is taken from Unidatas ucar.unidata.util.Misc method. I moved it here to not have it use the parseNumber because that would use a DecimalFormat which was picking up the Locale Decodes a string representation of a latitude or longitude and returns a double version (in degrees). Acceptible formats are:

 +/-  ddd:mm, ddd:mm:, ddd:mm:ss, ddd::ss, ddd.fffff ===>   [+/-] ddd.fffff
 +/-  ddd, ddd:, ddd::                               ===>   [+/-] ddd
 +/-  :mm, :mm:, :mm:ss, ::ss, .fffff                ===>   [+/-] .fffff
 +/-  :, ::                                          ===>       0.0
 Any of the above with N,S,E,W appended
 

Parameters:

latlon - string representation of lat or lon

Returns:

the decoded value in degrees

safeGet

public static java.lang.Object safeGet(java.util.List list,
                                       int index)
