Illustration of the Times projection

Projection method

Pseudo cylindrical. Meridians are equally spaced curves. Parallels are straight lines increasing in separation with distance from the equator.

Lines of contact

Two lines at 45° N and S.

Linear graticules

All parallels and the central meridian.

Properties

Shape

Moderate distortion.

Area

Increasing distortion with distance from 45° N and S.

Direction

Generally distorted.

Distance

Scale is correct along parallels at 45° N and S.

Limitations

Useful only for world maps.

Uses and applications

Used for world maps by Bartholomew Ltd., a British mapmaking company, in The Times Atlas.
