Member Data Documentation

◆ CTProjection

short GTIFDefn::CTProjection

GeoTIFF identifier for underlying projection method. While some of these values have corresponding vlaues in EPSG (Projection field), others do not. For example CT_TransverseMercator.

◆ Datum

short GTIFDefn::Datum

Datum from GeogGeodeticDatumGeoKey tag. For example Datum_WGS84

◆ Ellipsoid

short GTIFDefn::Ellipsoid

Ellipsoid identifier from GeogELlipsoidGeoKey. For example Ellipse_Clarke_1866.

◆ GCS

short GTIFDefn::GCS

From GeographicTypeGeoKey tag. For example GCS_WGS_84 or GCS_Voirol_1875_Paris. Includes datum and prime meridian value.

◆ MapSys

int GTIFDefn::MapSys

Special zone map system code (MapSys_UTM_South, MapSys_UTM_North, MapSys_State_Plane or KvUserDefined if none apply.

◆ Model

short GTIFDefn::Model

From GTModelTypeGeoKey tag. Can have the values ModelTypeGeographic or ModelTypeProjected.

◆ nParms

int GTIFDefn::nParms

Number of projection parameters in ProjParm and ProjParmId.

◆ PCS

short GTIFDefn::PCS

From ProjectedCSTypeGeoKey tag. For example PCS_NAD27_UTM_zone_3N.

◆ PM

short GTIFDefn::PM

Prime meridian from GeogPrimeMeridianGeoKey. For example PM_Greenwich or PM_Paris.

◆ PMLongToGreenwich

double GTIFDefn::PMLongToGreenwich

Decimal degrees of longitude between this prime meridian and Greenwich. Prime meridians to the west of Greenwich are negative.

◆ ProjCode

short GTIFDefn::ProjCode

Projection id from ProjectionGeoKey. For example Proj_UTM_11S.

◆ Projection

short GTIFDefn::Projection

EPSG identifier for underlying projection method. From the EPSG TRF_METHOD table.

◆ ProjParm

double GTIFDefn::ProjParm[MAX_GTIF_PROJPARMS]

Projection parameter value. The identify of this parameter is established from the corresponding entry in ProjParmId. The value will be measured in meters, or decimal degrees if it is a linear or angular measure.

◆ ProjParmId

int GTIFDefn::ProjParmId[MAX_GTIF_PROJPARMS]

Projection parameter identifier. For example ProjFalseEastingGeoKey. The value will be 0 for unused table entries.

◆ SemiMajor

double GTIFDefn::SemiMajor

The length of the semi major ellipse axis in meters.

◆ SemiMinor

double GTIFDefn::SemiMinor

The length of the semi minor ellipse axis in meters.

◆ UOMAngle

short GTIFDefn::UOMAngle

The angular units of the GCS.

◆ UOMAngleInDegrees

double GTIFDefn::UOMAngleInDegrees

One UOMAngle = UOMLengthInDegrees degrees.

◆ UOMLength

short GTIFDefn::UOMLength

From ProjLinearUnitsGeoKey. For example Linear_Meter.

◆ UOMLengthInMeters

double GTIFDefn::UOMLengthInMeters

One UOMLength = UOMLengthInMeters meters.

◆ Zone

int GTIFDefn::Zone

UTM, or State Plane Zone number, zero if not known.
