9  * ABSTRACT
10  *
11  * This component provides conversions between Geodetic coordinates (latitude,
12  * longitude in radians and height in meters) and Local Cartesian coordinates
13  * (X, Y, Z).
14  *
15  * ERROR HANDLING
16  *
17  * This component checks parameters for valid values. If an invalid value
18  * is found, the error code is combined with the current error code using
19  * the bitwise or. This combining allows multiple error codes to be
20  * returned. The possible error codes are:
21  *
22  * LOCCART_NO_ERROR : No errors occurred in function
23  * LOCCART_LAT_ERROR : Latitude out of valid range
24  * (-90 to 90 degrees)
25  * LOCCART_LON_ERROR : Longitude out of valid range
26  * (-180 to 360 degrees)
27  * LOCCART_A_ERROR : Semi-major axis less than or equal to zero
28  * LOCCART_INV_F_ERROR : Inverse flattening outside of valid range
29  * (250 to 350)
30  * LOCCART_ORIGIN_LAT_ERROR : Origin Latitude out of valid range
31  * (-90 to 90 degrees)
32  * LOCCART_ORIGIN_LON_ERROR : Origin Longitude out of valid range
33  * (-180 to 360 degrees)
34  * LOCCART_ORIENTATION_ERROR : Orientation angle out of valid range
35  * (-360 to 360 degrees)
36  *

38  * REUSE NOTES
39  *
40  * LOCCART is intended for reuse by any application that performs
41  * coordinate conversions between geodetic coordinates or geocentric
42  * coordinates and local cartesian coordinates..
