Latitude and Longitude
Information
The latitude and longitude scales presented on the chart are broken down
into whole degrees (fig. 1-11). Each degree is usually broken down into
minutes on small-scale charts (remember, small scale = large area.) The
large-scale chart breaks down even further into minutes (') and seconds
(").
It is important that you understand these scales.
Remember that each degree (°) of latitude or longitude equals 60 minutes
(60'), and that each minute (1') equals 60 seconds (60"). Seconds of
latitude and longitude may also be expressed as a decimal fraction.
