Member Enumeration Documentation

CameraPriority

enum Isis::UniversalGroundMap::CameraPriority

This enum is used to define whether to use a camera or projection primarily, and which to fall back on.

Enumerator
CameraFirst	This is the default because cameras are projection-aware. Use the camera for additional power if available, and fall back to projection
ProjectionFirst	Use the projection for functionality well outside the original image if available, and fall back to camera.

Constructor & Destructor Documentation

UniversalGroundMap()

Isis::UniversalGroundMap::UniversalGroundMap	(	Cube &	cube,
		CameraPriority	priority = CameraFirst )

Constructs a UniversalGroundMap object from a cube.

Parameters

cube	The Cube to create the UniversalGroundMap from
priority	Try to make a camera or projection first

References _FILEINFO_, Isis::IException::append(), CameraFirst, Isis::CameraFactory::Create(), Isis::ProjectionFactory::CreateFromCube(), Isis::Cube::fileName(), Isis::Cube::label(), and Isis::IException::Unknown.

~UniversalGroundMap()

Isis::UniversalGroundMap::~UniversalGroundMap

(

)

Destroys the UniversalGroundMap object.

Member Function Documentation

Camera()

Isis::Camera * Isis::UniversalGroundMap::Camera ( ) const

inline

Return the camera associated with the ground map (NULL implies none)

GroundRange()

bool Isis::UniversalGroundMap::GroundRange	(	Cube *	cube,
		Latitude &	minLat,
		Latitude &	maxLat,
		Longitude &	minLon,
		Longitude &	maxLon,
		bool	allowEstimation = true )

Find the lat/lon range of the image.

This will use the image footprint, camera, or projection in order to find a good result.

Parameters

Cube*	This is required for estimation. You can pass in NULL (it will disable estimation).
minLat	This is an output: minimum latitude
maxLat	This is an output: maximum latitude
minLon	This is an output: minimum longitude
maxLon	This is an output: maximum longitude
allowEstimation	If this is true then extra efforts will be made to guess the ground range of the input. This can still fail.

Returns

True if a ground range was found, false if no ground range could be determined. Some lat/lon results may still be populated; their values are undefined.
