Get the defaul Datum for an instance of CoordinateSystem. For example, instances of OSGB usually use the OSGB 1936 datum.- ???:

???????:CoordinateSystem
The default Ellipsoid used by instances of this CoordinateSystem For example, a CoordinateSystem of type OSGB has the AirySphere as its default Ellipsoid- ???:

-
f0
public double f0()The scale factor on the Central Meridian. Generally, Transverse Mercator projections increasingly exaggerate distances further from the central meridian. It is usual to reduce the scale factor at the central meridian to compensate for this effect and optimise the scale over the area of interest.- ???:
f0
???TransverseMercator
- ??:
- the value of the ScaleFactor at the central meridian.
-
n0
public double n0()n0() defines the "false northing" distance of the projection. False origins are usually used with TM projections to ensure that easting and northing distances are always positive over the area of interest. n0() is used as an offset to the grid so that the "true origin" appears to have a northing value equal to n0().- ???:
n0
???TransverseMercator
- ??:
- The false northing distance (double)
-
phi0
public double phi0()phi0() defines the latitude of the true origin of the projection. Note, however, that many Transverse Mercator projections employ a false origin. See n0() and e0() .- ???:
phi0
???TransverseMercator
- ??:
- The latitude of the true origin (radians)
