History

2005-11-09 Tracie Sucharski Added HasProjection method.

2006-03-20 Elizabeth Miller Added camera, projection, and Resolution methods and documentation

2006-03-31 Elizabeth Miller Added unitTest

2006-05-17 Elizabeth Miller Depricated CameraManager to CameraFactory

2007-02-06 Tracie Sucharski Added SetBand method.

2007-02-06 Steven Lambright Fixed documentation

2009-04-24 Steven Koechle Added a check to SetUniversalGround that makes sure the result is on the cube before returning true.

2010-04-09 Sharmila Prasad Added an API to check for camera in an image

2010-04-28 Mackenzie Boyd Fixed dereferencing issue in constructor that takes a cube.

2011-01-25 Steven Lambright Added CameraPriority and SetGround. The CameraPriority was for grid to use projections by default so they would work across the image regardless of the camera. The SetGround is so that conversions between lat/lon types are simply handled and allows a clean interface to use the new Latitude and Longitude classes.

2011-01-25 Eric Hyer - Added SetGround method for Surface Points

2012-03-22 Steven Lambright - Added GroundRange() method because I needed a ground range in the qview nomenclature tool and this seemed like the best place to put it. The Cube paramater is optional.

2012-06-29 Steven Lambright and Kimberly Oyama - Made the estimation section of GroundRange() sample more points by walking the perimeter, the two corner to corner diagonals, and a plus that intersects in the center of the image. This ensures that the entire longitude range is returned. Fixes #855.

2012-12-20 Debbie A. Cook - Changed to use TProjection instead of Projection. References #775.

2013-04-24 Tracie Sucharski - Added ring plane functionality to methods UniversalLatitude() and UniversalLongitude(). Reference #775.

2012-04-24 Jeannie Backer - Removed prototype for constructor that has been removed from this class. References #775.

2017-06-26 Jesse Mapel - Added a new method to set the universal ground point without adjusting for the longitude domain. Fixes #2185.

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.

Definition at line 75 of file UniversalGroundMap.h.

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

Definition at line 33 of file UniversalGroundMap.cpp.

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

◆ ~UniversalGroundMap()

Isis::UniversalGroundMap::~UniversalGroundMap ( )

Destroys the UniversalGroundMap object.

Definition at line 80 of file UniversalGroundMap.cpp.

References p_camera, and p_projection.

Member Function Documentation

◆ Camera()

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

inline

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

Definition at line 136 of file UniversalGroundMap.h.

References p_camera.

Referenced by Isis::ImagePolygon::Create(), Isis::CubeViewport::CubeViewport(), Isis::MosaicSceneItem::drawImage(), Isis::ImagePolygon::FixPolePoly(), Isis::GroundGrid::GroundGrid(), Isis::ImagePolygon::initCube(), and Isis::ImagePolygon::SetImage().

◆ 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.
