Appendix B: Using a compass
Previous (Appendix A: Using a dot grid (to measure area))Index (Table of contents)Next (Appendix C: Using coordinates)

A "compass rose" is an illustration such as the one on this page, showing the points of the compass.

The main directions: north, south, east, west are called the "cardinal points" of the compass.

Always look for the compass rose, or perhaps a "north arrow", to see in which direction an image is oriented. North isn't always to the top, although that is a popular convention.
