Great Circle Sailing By Chart
Navigations can most easily solve great-circle sailing problems graphically, DMAHTC publishes several gnomonic projections covering the principal navigable waters of the world. On these great circle charts, any straight line is a great circle. The chart, however, is not conformal; therefore, the navigator cannot directly measure directions and distances as on a Mercator chart.
The usual method of using a gnomonic chart is to plot the route and pick points along the track every 5°of longitude using the latitude and longitude scales in the immediate vicinity of each point. These points are then transferred to a Mercator chart and connected by rhumb lines.
(注) DMAHTC: Defense Mapping Agency Hydrographic/Topographic Center conformal=(adj.) Having correct angular representation gnomonic projections/gnomonic chart = great circle chart(s)
