/* RSC IDENTIFIER: SINUSOIDAL
*
* ABSTRACT
*
* This component provides conversions between Geodetic coordinates
* (latitude and longitude in radians) and Sinusoid projection coordinates
* (easting and northing in meters).
*
* ERROR HANDLING
*
* This component checks parameters for valid values. If an invalid value
* is found, the error code is combined with the current error code using
* the bitwise or. This combining allows multiple error codes to be
* returned. The possible error codes are:
*
* SINU_NO_ERROR : No errors occurred in function
* SINU_LAT_ERROR : Latitude outside of valid range
* (-90 to 90 degrees)
* SINU_LON_ERROR : Longitude outside of valid range
* (-180 to 360 degrees)
* SINU_EASTING_ERROR : Easting outside of valid range
* (False_Easting +/- ~20,000,000 m,
* depending on ellipsoid parameters)
* SINU_NORTHING_ERROR : Northing outside of valid range
* (False_Northing +/- ~10,000,000 m,
* depending on ellipsoid parameters)
* SINU_CENT_MER_ERROR : Origin longitude outside of valid range
* (-180 to 360 degrees)
* SINU_A_ERROR : Semi-major axis less than or equal to zero
* SINU_INV_F_ERROR : Inverse flattening outside of valid range
* (250 to 350)
*
* REUSE NOTES
*
* SINUSOIDAL is intended for reuse by any application that performs a
* Sinusoid projection or its inverse.
*
* REFERENCES
*
* Further information on SINUSOIDAL can be found in the Reuse Manual.
*
* SINUSOIDAL originated from : U.S. Army Topographic Engineering Center

*
* LICENSES
*
* None apply to this component.
*
* RESTRICTIONS
*
* SINUSOIDAL has no restrictions.
*
* ENVIRONMENT
*
* SINUSOIDAL was tested and certified in the following environments:
*
* 1. Solaris 2.5 with GCC, version 2.8.1
* 2. Windows 95 with MS Visual C++, version 6
