/** |
|
| 50 |
* Mercator Cylindrical Projection. The parallels and the meridians are straight lines and |
|
| 51 |
* cross at right angles; this projection thus produces rectangular charts. The scale is true |
|
| 52 |
* along the equator (by default) or along two parallels equidistant of the equator (if a scale |
|
| 53 |
* factor other than 1 is used). This projection is used to represent areas close to the equator. |
|
| 54 |
* It is also often used for maritime navigation because all the straight lines on the chart are |
|
| 55 |
* <em>loxodrome</em> lines, i.e. a ship following this line would keep a constant azimuth on its |
|
| 56 |
* compass. |
|
| 57 |
* <br><br> |
|
| 58 |
* |
|
| 59 |
* This implementation handles both the 1 and 2 stardard parallel cases. |
|
| 60 |
* For <code>Mercator_1SP</code> (EPSG code 9804), the line of contact is the equator. |
|
| 61 |
* For <code>Mercator_2SP</code> (EPSG code 9805) lines of contact are symmetrical |
|
| 62 |
* about the equator. |
