The International (INT) Chart

The idea of a common, worldwide chart series (INT Charts) produced to a single set of agreed specifications was adopted in 1971. Under this arrangement, member nations wishing to print their own versions of another members INT charts, may do so by obtaining (by mutual agreement), copies of the necessary reproducible material and printing their own copies.

The programme for small scale (1/10 000 000 and 1/3 500 000) INT charts, has been completed and many of the charts at medium and larger scales have also been publised.
