LLtoUTM() [1/2]

static void gps_common::LLtoUTM ( const double  Lat, const double  Long, double &  UTMNorthing, double &  UTMEasting, char *  UTMZone  )

inlinestatic

Convert lat/long to UTM coords. Equations from USGS Bulletin 1532

East Longitudes are positive, West longitudes are negative. North latitudes are positive, South latitudes are negative Lat and Long are in fractional degrees

LLtoUTM() [2/2]

static void gps_common::LLtoUTM ( const double  Lat, const double  Long, double &  UTMNorthing, double &  UTMEasting, std::string &  UTMZone  )

inlinestatic

Definition at line 210 of file conversions.h.

UTM()

static void gps_common::UTM ( double  lat, double  lon, double *  x, double *  y  )

inlinestatic

Utility function to convert geodetic to UTM position

Units in are floating point degrees (sign for east/west)

Units out are meters

Definition at line 57 of file conversions.h.

UTMLetterDesignator()

static char gps_common::UTMLetterDesignator ( double  Lat )

inlinestatic

Determine the correct UTM letter designator for the given latitude

Returns

'Z' if latitude is outside the UTM limits of 84N to 80S

UTMtoLL() [1/2]

static void gps_common::UTMtoLL ( const double  UTMNorthing, const double  UTMEasting, const char *  UTMZone, double &  Lat, double &  Long  )

inlinestatic

Converts UTM coords to lat/long. Equations from USGS Bulletin 1532

East Longitudes are positive, West longitudes are negative. North latitudes are positive, South latitudes are negative Lat and Long are in fractional degrees.
