Zenithal Projection In this type of projection all the bearings are true to compass
direction from the centre of the map. By virtue of having the correct direction from
the centre of the projection to various other points this projection is also known ...

Fundamentals of Cartography
If the light is placed at the centre of the generating globe we get a zenithal
projection which is called gnomonic. If the light is placed at a point diametrically
opposed to the point where the plane touches the globe, then the projected
image gives ...

Map Projections: A Working Manual
Project the net of the zenithal projection orthographically on this plane. We then
have a projection of the hemisphere bounded by an ellipse of which the major
axis is twice the minor. Now halve the scale in longitude : that is to say, number
the ...
It is also used for meteorological charts, i.e. the weather map of India is shown on
Mercator's Projection. Zenithal Projection Zenithal Projections are obtained by
projecting the graticule of latitudes and longitudes on a tangent plane surface.

Map Work And Practical Geography, 4E
When the plane is placed tangentially at a point on the equator, the projection is
called a zenithal projection (equatorial Plane Plane is tangent to the sphere at
the South Pole. Fig. 57 case). When placed tangentially at a point between a pole
...

Surveying and Charting of the Seas
The geographical position of the area to be charted will necessitate the use of a
polar, an equatorial, or an oblique version of the zenithal projection selected.
Five zenithal projections will be discussed hereunder, three perspective
projections ...

When the developable surface touches the globe at the pole the resulting
projection is called (a) polar projection (b) oblique projection (c) zenithal
projection (d) equatorial projection 73. An oblique projection is obtained when (a)
the ...
... and zenithal projections are special cases of conic projection: when the pole
itself becomes the selected parallel, the angle at the apex will be 180° — the
surface of the cone will become similar to the tangent plane of zenithal projection.
True compass bearings are maintained from the center through all points along
the meridjans on a zenithal projection, making such maps ideal for navigation. An
example of this projection is the Gnomonic Projection (Fig. 4-17). Here the globe
