This package provides efficient and accurate geographic coordinate
transformations in the Java language.
Most of these are based on mathematical approximations that
eliminate many of the trigonometric calls used in the exact solutions. They
are accurate to within a one millimeter error ball of the exact solution, while
being substantially faster.
Other transforms are provided through
community contributions and may offer less
accuracy and efficiency.
The currently supported coordinate systems are defined as follows:
- Geodetic Coordinate System ( GDC)
- GeoCentric Coordinate System (GCC)
- Universal Transverse Mercator (UTM)
- Mercator (MER)
- Lambert Conformal Conic (LCC)
- Ordinance Survey Great Britain (OSGB)
The GDC, UTM, and GCC algorithms first appeared as part of the SEDRIS Coordinate
Transformation API and were subsequently modified for this package.
The OSGB, MER, and LCC algorithms were
contributed through community involvement
and are not derived from the SEDRIS API.
package is not part of the SEDRIS project, and the Java code written for this
package has not been certified or tested for correctness by NIMA.
