A false easting of 500000 m is assigned to the central meridian ( 24?east ), so eastings are always positive.
22.
The isoscale lines with k = 1 are slightly curved lines approximately 180 km east and west of the central meridian.
23.
This variation is smallest along the central meridian ( north-south line ) of the map, and greatest at the map edges.
24.
Where " ? " is the longitude from the central meridian of the projection, and " ? " is the latitude.
25.
In the secant version the lines of true scale on the projection are no longer parallel to central meridian; they curve slightly.
26.
In all of these formulas, " ? " is the longitude from the central meridian and " ? " is the latitude.
27.
The minimum distortion is on the central meridian at latitudes of 30 degrees ( North and South ) . ( Other examples ).
28.
Because of the body's rotation and orbital alignment with the observer the central meridian changes with time, as it is based on the observer's point of view.
29.
Used as early as the 16th century, this projection shows distances accurately along the central meridian and the equator; areas furthest from these lines are the most distorted.
30.
Along parallels, each point from the surface is mapped at a distance from the central meridian that is proportional to its difference in longitude from the central meridian.
