/* RSC IDENTIFIER: USNG
*
* ABSTRACT
*
* This component converts between geodetic coordinates (latitude and
* longitude) and United States National Grid (USNG) coordinates.
*
* 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:
*
* USNG_NO_ERROR : No errors occurred in function
* USNG_LAT_ERROR : Latitude outside of valid range
* (-90 to 90 degrees)
* USNG_LON_ERROR : Longitude outside of valid range
* (-180 to 360 degrees)
* USNG_STR_ERROR : An USNG string error: string too long,
* too short, or badly formed
* USNG_PRECISION_ERROR : The precision must be between 0 and 5
* inclusive.
* USNG_A_ERROR : Semi-major axis less than or equal to zero
* USNG_INV_F_ERROR : Inverse flattening outside of valid range
* (250 to 350)
* USNG_EASTING_ERROR : Easting outside of valid range
* (100,000 to 900,000 meters for UTM)
* (0 to 4,000,000 meters for UPS)
* USNG_NORTHING_ERROR : Northing outside of valid range
* (0 to 10,000,000 meters for UTM)
* (0 to 4,000,000 meters for UPS)
* USNG_ZONE_ERROR : Zone outside of valid range (1 to 60)
* USNG_HEMISPHERE_ERROR : Invalid hemisphere ('N' or 'S')
*
* REUSE NOTES
*
* USNG is intended for reuse by any application that does conversions
* between geodetic coordinates and USNG coordinates.
*
* REFERENCES
*
* Further information on USNG can be found in the Reuse Manual.
*
* USNG originated from : Federal Geographic Data Committee
* 590 National Center
* 12201 Sunrise Valley Drive
* Reston, VA 22092
*
* LICENSES
*
* None apply to this component.
*
* RESTRICTIONS
*
*
* ENVIRONMENT
*
* USNG 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
