Detailed Description

Convert between undistorted focal plane and ground coordinates.

This base class is used to convert between undistorted focal plane coordinates (x/y) in millimeters and ground coordinates lat/lon. This class handles the case of framing cameras.

Constructor & Destructor Documentation

Isis::VimsSkyMap::VimsSkyMap ( Camera *  parent,
Pvl &  lab 
)

Constructs the VimsSkyMap object.

Parameters:
parent A pointer to the parent Camera object
lab Pvl labels for the image
virtual Isis::VimsSkyMap::~VimsSkyMap (  )  [inline, virtual]

Destroys the VimsSkyMap object.

bool Isis::VimsSkyMap::SetFocalPlane ( const double  ux,
const double  uy,
const double  uz 
) [virtual]

Compute ground position from focal plane coordinate.

This method will compute the ground position given an undistorted focal plane coordinate. Note that the latitude/longitude value can be obtained from the camera class passed into the constructor.

Parameters:
ux distorted focal plane x in millimeters
uy distorted focal plane y in millimeters
uz distorted focal plane z in millimeters
Returns:
conversion was successful

Reimplemented from Isis::CameraSkyMap.

bool Isis::VimsSkyMap::SetSky ( const double  ra,
const double  dec 
) [virtual]

Sets the sky position to the given ra and dec.

Parameters:
ra the right ascension
dec the declination
Returns:
set sky was successful

Reimplemented from Isis::CameraSkyMap.
