| pe_verttran_parameters | |
Retrieves the parameters of a vertical transformation
void pe_verttran_parameters (PE_VERTTRAN verttran, PE_PARAMETER parameters[PE_PARM_MAX]);
| verttran | Vertical transformation object |
| parameters | The array of any needed vertical transformation parameters |
Pe_verttran_parameters returns the parameters of a vertical transformation. The parameters can include the following:
PE_PARM_VO 0 /* Vertical Offset */
PE_PARM_INCN 13 /* Inclination North (plane of meridian) */
PE_PARM_INCE 14 /* Inclination East (perpendicular to above) */
PE_PARM_LAM0 2 /* Longitude of evaluation point */
PE_PARM_PHI0 6 /* Latitude of evaluation point */
PE_PARM_ND 15 /* Name of Dataset for grid-based transforms */
On success, returns an array of parameters for the vertical transformation; on failure, returns a null pointer.
PE_PARAMETER vt_par[PE_PARM_MAX];
pe_verttran_parameter(wgs2egm, vt_par);
