Orthographic Map Projection.
This class provides methods for the forward and inverse equations of an Orthographic map projection (for a sphere).
The Orthographic projection is an azimuthal projection. Latitudes and longitudes are ellipses, circles, or straight lines. Only one hemisphere can be projected. Scale is true at the point (center latitude, center longitude).
The code was converted to C++ from the C version of the USGS General Cartographic Transformation Package (GCTP). This class inherits Projection and provides the two virtual methods SetGround (forward) and SetCoordinate (inverse) and a third virtual method, XYRange, for obtaining projection coordinate coverage for a latitude/longitude window.
Please see the Projection class for a full accounting of all the methods available.
2005-08-22 Kris Becker - Fixed bug in XYRange method that computes the line/samp ranges as it was not correctly computing limb limits
2007-06-29 Steven Lambright - Added Mapping, MappingLatitudes and MappingLongitudes methods.
2008-05-09 Steven Lambright - Added Name, Version methods
2011-01-31 Steven Lambright - Improved ability to work with lat/lon ranges outside of what is possible to project. Now a lat,lon range of -90 to 90, 0 to 360 works. Improved XYRange method to have a better chance at success.
2012-06-15 Jeannie Backer - Added documentation. Added forward declaration of Pvl, PvlGroup to header file. Ordered includes in implementation file. Moved Name, Version, and TrueScaleLatitude to the implementation file. Minor modifications to comply with some coding standards. References #928.
2012-01-20 Debbie A. Cook - Changed to use TProjection instead of Projection. References #775.
2013-02-22 Kimberly Oyama and Debbie Cook - XYRange() and SetCoordinate() were modified because XYRange() was returning the wrong x/y ranges caused by a false failure in SetCoordinate(). Added a case to the unit test to check the x/y values when the lat/lon ranges are smaller than the possible range of the projection (half the planet). Fixes #798.
2013-07-25 Kimberly Oyama - Fixed the longitude equation for the south pole by making x positive instead of negative. Fixes #1719.
2013-08-20 Kimberly Oyama - Removed code for the special case, clat = 0, in the constructor to give the correct longitude range when clat = 0. Added a range check in SetCoordinate() to make sure m_longitude is in the correct domain. Fixes #1471.

This method is used to find the XY range for oblique aspect projections (non-polar projections) by "walking" around each of the min/max lat/lon.
minX | Minimum x projection coordinate which covers the latitude longitude range specified in the labels. |
maxX | Maximum x projection coordinate which covers the latitude longitude range specified in the labels. |
minY | Minimum y projection coordinate which covers the latitude longitude range specified in the labels. |
maxY | Maximum y projection coordinate which covers the latitude longitude range specified in the labels. |
This method searches for extreme (min/max/discontinuity) coordinate values along the constBorder line between minBorder and maxBorder (that is, across latitudes/longitudes). This method locates the extrema by utilizing the findExtreme() method until the coordinate values converge. Then, extremeVal parameter is updated with this value before returning.
Discontinuities are stored in m_specialLatCases and m_specialLonCases so they may be checked again later, which creates significantly more accuracy in some cases.
minBorder | Minimum latitude or longitude to search between. |
maxBorder | Maximum latitude or longitude to search between. |
extremeVal | The resulting global coordinate value (min or max value for x or y, depending on findMin and searchX) on the constBorder. |
constBorder | The latitude or longitude that remains constant. The method will step along this border. |
searchX | Indicates whether the method is searching for a min or max x-coordinate. If false the method searches for min or max y-coordinate. |
searchLongitude | Indicates whether the method will search along a longitude. If true, constBorder is longitude and all other borders are latitudes. If false, the method searches a latitude (constBorder is a lat, other borders lons). |
findMin | Indicates whether the method is looking for a minimum coordinate value. If false, the method is looking for a maximum value. |
Searches for extreme (min/max/discontinuity) coordinate values across latitudes/longitudes.
This method looks for these extrema along the constBorder between minBorder and maxBorder by stepping along constBorder (10 times) from the minBorder and maxBorder. Then, the range of this extreme value is recorded in minBorder and maxBorder and the coordinate values corresponding to these new borders are stored in minBorderX, minBorderY, maxBorderX and maxBorderY.
This function should be used by calling it repeatedly until minBorderX and minBorderY do not equal maxBorderX and maxBorderY, respectively. Discontinuities will cause the minBorderX, minBorderY, maxBorderX and maxBorderY to never converge. If minBorderX never comes close to maxBorderX or minBorderY never comes close to maxBorderY, then between minBorder and maxBorder is the value of the most extreme value. In this case, either the smaller or larger of the x or y values found will be correct, depending on the values of findMin and searchX.
minBorder | Minimum latitude or longitude to search between. This value gets updated to a more precise range. |
maxBorder | Maximum latitude or longitude to search between. This value gets updated to a more precise range. |
minBorderX | The x-value corresponding to the lower resultant minBorder and the constBorder, which is more accurate when nearly equal to maxBorderX. |
minBorderY | The y-value corresponding to the lower resultant minBorder and the constBorder, which is more accurate when nearly equal to maxBorderY. |
maxBorderX | The x-value corresponding to the higher resultant maxBorder and the constBorder, which is more accurate when nearly equal to minBorderX. |
maxBorderY | The y-value corresponding to the higher resultant maxBorder and the constBorder, which is more accurate when nearly equal to minBorderY. |
constBorder | The latitude or longitude that remains constant. The method will step along this border. |
searchX | Indicates whether the method is searching for a min or max x-coordinate. If false the method searches for min or max y-coordinate. |
searchLongitude | Indicates whether the method will search along a longitude. If true, constBorder is longitude and all other borders are latitudes. If false, the method searches a latitude (constBorder is a lat, other borders lons). |
findMin | Indicates whether the method is looking for a minimum coordinate value. If false, the method is looking for a maximum value. |
This function sets the ground for the given border values. It calls the SetGround(lat, lon) method with the appropriate lat/lon values, depending on whether variableIsLat is true.
This method is used by doSearch and findExtreme in order to set the ground correctly each time.
variableBorder | The latitude or longitude that is variable in the search methods. |
constBorder | The latitude or longitude that is constant in the search methods. |
variableIsLat | Indicates whether variableBorder is the latittude value and constBorder is the longitude value. If false, variableBorder is the longitude value and constBorder is the latitude value. |

This method is used to set a world coordinate.
A world coordinate is a different coordinate type that has a one-to-one mapping to the projection coordinate system. For example, mapping pixel samples and lines to projection x's and y's. The Set forces an attempted calculation of the corresponding latitude/longitude position. This may or may not be successful and a status is returned as such. Note that is only applies if the Projection object was given an WorldMapper object during construction. If an WorldMapper was not supplied then SetWorld operates exactly the same as SetCoordinate (impling that world coordinate and projection coordinate are identical).

If desired the programmer can use this method to set a world mapper to be used in the SetWorld, WorldX, and WorldY methods.
Mappers typically transform a projection coordinate (x/y) into the desired working coordinate system, for example, cube pixels or inches on a piece of paper. They transform in both directions (world to projection and projection to world). This allows for conversions from line/sample to latitude/longitude and vice versa. This projection will take ownership of the WorldMapper pointer.

This method is used to determine the x/y range which completely covers the area of interest specified by the lat/lon range.
The latitude/longitude range may be obtained from the labels. The purpose of this method is to return the x/y range so it can be used to compute how large a map may need to be. For example, how big a piece of paper is needed or how large of an image needs to be created. The method may fail as indicated by its return value.

This convience function is established to assist in the development of the XYRange virtual method.
It allows the developer to test ground points (lat/lon) to see if they produce a minimum/maximum projection coordinate. For example in Sinusoidal,
latitude | Test for min/max projection coordinates at this latitude |
longitude | Test for min/max projection coordinates at this longitude |
