Scale identification for CHS Charts

We refer to the relationship between the size of the chart and the earth as 'natural scale.' For example, 1:15 000 means that 1 unit on the chart equals 15 000 units on the earth. The following are examples of different types and scales of charts and their uses.

  • Harbour charts are:
    • large scale, 1:2 001 to 1:20 000
    • used for navigation in harbours or intricate, hazardous, shoal-infested waters
  • Approach charts are:
    • 1:20 001 to 1:50 000
    • used for approaching coasts where a lot of detail is required
  • Coastal charts are:
    • 1:50 001 to 1:150 000
    • used in fisheries charts
    • used to show continuous extensive coverage with sufficient inshore detail to make landfall sightings easy

    • used in fisheries charts
    • give extensive offshore coverage with sufficient inshore detail to make landfall sightings easy
