◆ stringToCoordinateType()

SurfacePoint::CoordinateType Isis::SurfacePoint::stringToCoordinateType ( QString type)
static

This method converts the given string value to a SurfacePoint::CoordinateType enumeration.

Currently (March 31, 2017) accepted inputs are listed below.
This method is case insensitive.

Parameters
typeThe coordinate type name to be converted
Returns
CoordinateType The enumeration corresponding to the input name

◆ ToNaifArray()

void Isis::SurfacePoint::ToNaifArray ( double naifOutput[3]) const

A naif array is a c-style array of size 3.

The element types are double... keep in mind a SpiceDouble is a double. The values' units are kilometers because that is the unit naif works in. The first element is X, the second Y, and the third Z.

Parameters
naifOutputThe naif array to populate with the surface point's XYZ position.
