Sinusoidal Map Projection.
This class provides methods for the forward and inverse equations of a Sinusoidal Equal-Area map projection (for a sphere).
The Sinusoidal projection is an equal-area, psuedo-cylindrical projection. The poles are represented as points, the center longitude and all latitudes as straight lines and all other longitudes as sinusoidal curves. The latitudes are equally spaced and parallel and the longitudes are equally spaced. True scale is found along the center longitude and all latitudes.
The code was converted to C++ from the Fortran 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.
enum Isis::Projection::LatitudeType [inherited] |
This enum defines the types of Latitude supported in this class.
enum Isis::Projection::LongitudeDirection [inherited] |
| Isis::Sinusoidal::Sinusoidal | ( | Pvl & | label, |
| bool | allowDefaults = false |

| ) |
Constructs a Sinusoidal object.
| label | This argument must be a Label containing the proper mapping information as indicated in the Projection class. Additionally, the sinusoidal projection requires the center longitude to be defined in the keyword CenterLongitude. |
| allowDefaults | If set to false the constructor expects that a keyword of CenterLongitude will be in the label. Otherwise it will attempt to compute the center longitude using the middle of the longitude range specified in the labels. Defaults to false |

| double Isis::Projection::Scale | ( | ) | const [inherited] |
This method returns the scale for mapping world coordinates into projection coordinates.
For example, if the world coordinate system is an image then this routine returns the number of pixels per degree. Likewise, if the world coordinate system is a piece of paper, it might return the number of inches of paper per degree. If the SetWorldMapper method is not invoked then this method returns 1.0

| bool Isis::Projection::SetWorld | ( | const double | worldX, |

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).

| void Isis::Projection::SetWorldMapper | ( | WorldMapper * | mapper | ) | [inherited] |
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.
