/* RSC IDENTIFIER: UPS

|
|
*
|
|
* ABSTRACT
|
|
*
|
|
* This component provides conversions between geodetic (latitude
|
|
* and longitude) coordinates and Universal Polar Stereographic (UPS)
|
|
* projection (hemisphere, easting, and northing) 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:
|
|
*
|
|
* UPS_NO_ERROR : No errors occurred in function
|
|
* UPS_LAT_ERROR : Latitude outside of valid range
|
|
* (North Pole: 83.5 to 90,
|
|
* South Pole: -79.5 to -90)
|
|
* UPS_LON_ERROR : Longitude outside of valid range
|
|
* (-180 to 360 degrees)
|
|
* UPS_HEMISPHERE_ERROR : Invalid hemisphere ('N' or 'S')
|
|
* UPS_EASTING_ERROR : Easting outside of valid range,
|
|
* (0 to 4,000,000m)
|
|
* UPS_NORTHING_ERROR : Northing outside of valid range,
|
|
* (0 to 4,000,000m)
|
|
* UPS_A_ERROR : Semi-major axis less than or equal to zero
|
|
* UPS_INV_F_ERROR : Inverse flattening outside of valid range
|
|
* (250 to 350)
|
|
*
|
|
*
|
|
* REUSE NOTES
|
|
*
|
|
* UPS is intended for reuse by any application that performs a Universal
|
|
* Polar Stereographic (UPS) projection.
