Method of Projection - Cylindrical:
This is a normal, perspective projection onto a cylinder tangent at the Equator.
Points of Intersection:
Tangent or secant.
Linear Graticules:
Meridians and parallels are straight lines at right angles to each other. Meridians are equally spaced and 0.32 times the length of the Equator, when the Equator is the standard parallel. The farther the standard parallel is from the Equator, the greater the length of the meridians. Poles are lines of length equal to the Equator.
Properties:
Shape: Shape is true along the standard parallels of the normal aspect. Shape distortion is severe near the poles of the normal aspect.
Area: There is no distortion of area.
Direction: Local angles are correct along standard parallels or standard lines. Direction is distorted elsewhere.
Distance: Scale is true along the Equator. Scale distortion is severe near the poles of the normal aspect
Limitations:
Recommended for narrow areas extending along the central line. Severe distortion of shape and scale near the poles.
Uses and Applications:
Suitable for equatorial regions.
Suitable for regions of north-south extent or those following an oblique central line, when using a transverse or oblique view, respectively.
