|
|
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 from GeogGeodeticDatumGeoKey tag. For example Datum_WGS84 |
|
|
Ellipsoid identifier from GeogELlipsoidGeoKey. For example Ellipse_Clarke_1866. |
|
|
From GeographicTypeGeoKey tag. For example GCS_WGS_84 or GCS_Voirol_1875_Paris. Includes datum and prime meridian value. |
|
|
Special zone map system code (MapSys_UTM_South, MapSys_UTM_North, MapSys_State_Plane or KvUserDefined if none apply. |
|
|
From GTModelTypeGeoKey tag. Can have the values ModelTypeGeographic or ModelTypeProjected. |
|
|
Number of projection parameters in ProjParm and ProjParmId. |
|
|
From ProjectedCSTypeGeoKey tag. For example PCS_NAD27_UTM_zone_3N. |
|
|
Prime meridian from GeogPrimeMeridianGeoKey. For example PM_Greenwich or PM_Paris. |
|
|
Decimal degrees of longitude between this prime meridian and Greenwich. Prime meridians to the west of Greenwich are negative. |
|
|
Projection id from ProjectionGeoKey. For example Proj_UTM_11S. |
|
|
EPSG identifier for underlying projection method. From the EPSG TRF_METHOD table. |
|
|
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. |
|
|
Projection parameter identifier. For example ProjFalseEastingGeoKey. The value will be 0 for unused table entries. |
|
|
The length of the semi major ellipse axis in meters. |
|
|
The length of the semi minor ellipse axis in meters. |
|
|
The angular units of the GCS. |
|
|
One UOMAngle = UOMLengthInDegrees degrees. |
|
|
From ProjLinearUnitsGeoKey. For example Linear_Meter. |
|
|
One UOMLength = UOMLengthInMeters meters. |
|
|
UTM, or State Plane Zone number, zero if not known. |
