Gnomonic projection, a projection of the circles of the sphere, in which the point of sight is taken at the center of the sphere, and the principal plane is tangent to the surface of the sphere.
Defn: According to the principles of the gnomonic projection.
The gnomonic projection derives its name from the connection between the methods of describing it and those for the construction of a gnomon or dial.

Gnomonic Projection The theory of this projection is to make a curved line appear and be a straight line on the chart, i.
Chart Projections The earth is projected, so to speak, upon a chart in three different ways--the Mercator Projection, the Polyconic Projection and the Gnomonic Projection.
Since all these charts are constructed on the Gnomonic Projection, it is only necessary to join any two points by a straight line to get the curved line or great circle track which your ship is to follow.
The Gnomonic Projection is of particular value in sailing long distance courses where following a curved line over the earth´s surface is the shortest distance between two points that are widely separated.
A modified or composite course can readily be laid out on a gnomonic chart.
To obtain the great circle or shortest course between two points it is therefore only necessary to draw a straight line between the points on a gnomonic chart.
The gnomonic chart is therefore useful in supplementing the mercator chart, supplying its deficiencies as to convenience in marking out great circle courses.
Gnomonic and conical projections are also used for the polar charts, differing little from the foregoing for moderate areas.
Gnomonic charts intended for taking off great circle courses are always described in their titles and are also easily recognized by the increased scale and distortion toward all the borders.
The method is only approximate and is limited in application, and the supplementary use of a gnomonic chart would appear to be preferable.
Gnomonic charts# are intended solely for laying down the great circle or shortest practicable courses between points, for which purpose they are very convenient.
The distortion, however, is necessarily enormous when the celestial sphere is presented in only six gnomonic maps.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "gnomonic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
