Meridians | Complex curves concave towards line of tangency (except +/– 180) |
Parallels | Complex curves concave towards the nearest pole |
Spacing Meridian | Increases away from the line of tangency |
Spacing Parallels | Increases away from the line of tangency |
Linear Scale | True along line of tangency OR Two lines equidistant from and parallel to the line of tangency |
Specialties | Cylinder is tangent to a great circle (but not meridian or equator) Shape is true only with any small area Enlargement of area increases away from line of tangency |
Uses | North & South America on a single map Satellite mapping Reasonably accurate within 15 band along line of tangency Navigation strip charts |
