/**
|
70 |
* Oblique Mercator Projection. A conformal, oblique, cylindrical projection
|
71 |
* with the cylinder touching the ellipsoid (or sphere) along a great circle
|
72 |
* path (the central line). The Mercator and Transverse Mercator projections
|
73 |
* can be thought of as special cases of the oblique mercator, where the central
|
74 |
* line is along the equator or a meridian, respectively. The Oblique Mercator
|
75 |
* projection has been used in Switzerland, Hungary, Madagascar,
|
76 |
* Malaysia, Borneo and the panhandle of Alaska.
|
77 |
* <br><br>
|
78 |
*
|
79 |
* The Oblique Mercator projection uses a (U,V) coordinate system, with the
|
80 |
* U axis along the central line. During the forward projection, coordinates
|
81 |
* from the ellipsoid are projected conformally to a sphere of constant total
|
82 |
* curvature, called the 'aposphere', before being projected onto the plane.
|
83 |
* The projection coordinates are further convented to a (X,Y) coordinate system
|
84 |
* by rotating the calculated (u,v) coordinates to give output (x,y) coordinates.
|
85 |
* The rotation value is usually the same as the projection azimuth (the angle,
|
86 |
* east of north, of the central line), but some cases allow a separate
|
87 |
* rotation parameter.
|
88 |
* <br><br>
|
89 |
*
|
90 |
* There are two forms of the oblique mercator, differing in the origin of
|
91 |
* their grid coordinates. The Hotine_Oblique_Mercator (EPSG code 9812) has grid
|
92 |
* coordinates start at the intersection of the central line and the equator of the
|
93 |
* aposphere. The Oblique_Mercator (EPSG code 9815) is the same, except the grid
|
94 |
* coordinates begin at the central point (where the latitude of center and
|
95 |
* central line intersect). ESRI separates these two case by appending
|
96 |
* "Natural_Origin" (for the Hotine_Oblique_Mercator) and "Center"
|
97 |
* (for the Obique_Mercator) to the projection names.
|
98 |
* <br><br>
|
99 |
*
|
100 |
* Two different methods are used to specify the central line for the
|
101 |
* oblique mercator: 1) a central point and an azimuth,
|
102 |
* east of north, describing the central line and
|
103 |
* 2) two points on the central line. The EPSG does not use the two point method,
|
104 |
* while ESRI separates the two cases by putting "Azimuth" and "Two_Point" in
|
105 |
* their projection names. Both cases use the point where the "latitude_of_center"
|
106 |
* parameter crosses the central line as the projection's central point.
|
107 |
* The central meridian is not a projection parameter, and is instead calculated
|
108 |
* as the intersection between the central line and the equator of the aposphere.
|
109 |
* <br><br>
|
110 |
*
|
111 |
* For the azimuth method, the central latitude cannot be +- 90.0 degrees
|
112 |
* and the central line cannot be at a maximum or minimum latitude at the central point.
|
113 |
* In the two point method, the latitude of the first and second points cannot be
|
114 |
* equal. Also, the latitude of the first point and central point cannot be
|
115 |
* +- 90.0 degrees. Furthermore, the latitude of the first point cannot be 0.0 and
|
116 |
* the latitude of the second point cannot be - 90.0 degrees. A change of
|
117 |
* 10^-7 radians can allow calculation at these special cases. Snyder's restriction
|
118 |
* of the central latitude being 0.0 has been removed, since the equaitons appear
|
119 |
* to work correctly in this case.
|
120 |
* <br><br>
|
121 |
*
|
122 |
* Azimuth values of 0.0 and +- 90.0 degrees are allowed (and used in Hungary
|
123 |
* and Switzerland), though these cases would usually use a Mercator or
|
124 |
* Transverse Mercator projection instead. Azimuth values > 90 degrees cause
|
125 |
* errors in the equations.
|
126 |
* <br><br>
|
127 |
*
|
128 |
* The oblique mercator is also called the "Rectified Skew Orthomorphic" (RSO).
|
129 |
* It appears is that the only difference from the oblique mercator is that
|
130 |
* the RSO allows the rotation from the (U,V) to (X,Y) coordinate system to be different
|
131 |
* from the azimuth. This separate parameter is called "rectified_grid_angle" (or
|
132 |
* "XY_Plane_Rotation" by ESRI) and is also included in the EPSG's parameters
|
133 |
* for the Oblique Mercator and Hotine Oblique Mercator.
|
134 |
* The rotation parameter is optional in all the non-two point projections and will be
|
135 |
* set to the azimuth if not specified.
|
136 |
* <br><br>
|
137 |
*
|
138 |

|
139 |
* <ul>
|
140 |
* <li>Oblique_Mercator (EPSG code 9815) - grid coordinates begin at the central point, has "rectified_grid_angle" parameter.</li>
