Function Documentation

getUTMZone()

int JUTM::getUTMZone ( const double longitude )

inline

Get UTM zone for given longitude.

Parameters

longitude

longitude [rad]

Returns

UTM zone

Definition at line 47 of file JUTMGrid.hh.

  {
    return 1 + int((PI + longitude) / UTM_ZONE_WIDTH_RAD);
  }

getUTMLongitude()

static double JUTM::getUTMLongitude ( const int zone )

inlinestatic

Get longitude of the central meridian for given UTM zone.

Parameters

zone

UTM zone

Returns

longitude of central meridian [rad]

Definition at line 59 of file JUTMGrid.hh.

  {
    return  -PI + (zone - 1) * UTM_ZONE_WIDTH_RAD + 0.5*UTM_ZONE_WIDTH_RAD;
  }

Variable Documentation

UTM_ZONE_WIDTH_RAD

const double JUTM::UTM_ZONE_WIDTH_RAD = 6.0 * PI / 180.0

static

UTM zone width [rad].

The UTM system consists of 60 zones, each 6-degrees of longitude in width.
The zones are numbered 1-60, beginning at 180-degrees longitude and increasing to the East.
