• a method of delineating the surface of a sphere upon a plane surface as if projected upon the surface of a cone; much used by makers of maps in Europe.
• a mode of representing the sphere, the spherical surface being projected upon the surface of a cone tangent to the sphere, the point of sight being at the center of the sphere.

Webster 1913

  equal-area map projection.
  

WordNet

  equal-area map projection.
  

WordNet

• See under Globular, Gnomonic, etc.

Webster 1913

• (Map Projection), a perspective projection of the surface of a hemisphere upon a plane parallel to the base of the hemisphere, the point of sight being taken in the axis produced beyond the surface of the opposite hemisphere a distance equal to the radius of the sphere into the sine of 45°.

Webster 1913

• 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. "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." Cyc. of Arts & Sciences.

Webster 1913

• a method of constructing geographical charts or maps, so that the surfaces, as delineated on a plane, have the same relative size as the real surfaces; that is, so that the relative actual areas of the different countries are accurately represented by the corresponding portions of the map.

Webster 1913

• noun an equal-area projection map of the globe; oceans are distorted in order to minimize the distortion of the continents
  

WordNet

• a projection made on a plane parallel to the horizon.

Webster 1913

• a species of orthographic projection, in which but a single plane of projection is used. It is so named from the fact that the projections of three equal lines, parallel respectively to three rectangular axes, are equal to one another. This kind of projection is principally used in delineating buildings or machinery, in which the principal lines are parallel to three rectangular axes, and the principal planes are parallel to three rectangular planes passing through the three axes.

Webster 1913

• noun a projection of the globe onto a flat map using a grid of lines of latitude and longitude
  

WordNet

• noun a map projection of the earth onto a cylinder; areas appear greater the farther they are from the equator
  Mercator projection.
  

WordNet

• noun a map projection of the earth onto a cylinder; areas appear greater the farther they are from the equator
  Mercator projection.
  

WordNet

• a mode of representing the sphere in which the meridians are drawn parallel to each other, and the parallels of latitude are straight lines whose distance from each other increases with their distance from the equator, so that at all places the degrees of latitude and longitude have to each other the same ratio as on the sphere itself.

Webster 1913

• a projection made by parallel lines drawn from every point of a figure and meeting the plane of projection obliquely.

Webster 1913

• . See under Orthographic.

Webster 1913

• that projection which is made by drawing lines, from every point to be projected, perpendicular to the plane of projection. Such a projection of the sphere represents its circles as seen in perspective by an eye supposed to be placed at an infinite distance, the plane of projection passing through the center of the sphere perpendicularly to the line of sight.

Webster 1913

• noun a map projection in which a small area is rendered in its true shape
  conformal projection.
  

WordNet

• a projection in which the angles in the figure to be projected are equal to the corresponding angles in the projected figure.

Webster 1913

• . (a) The plane on which the projection is made, corresponding to the perspective plane in perspective; called also principal plane. (b) (Descriptive Geom.) One of the planes to which points are referred for the purpose of determining their relative position in space.

Webster 1913

• a projection of the sphere in which the point of sight is at the center, and the plane of projection passes through one of the polar circles.

Webster 1913

• noun a conic projection of a map having distances between meridians equal to those distances on a globe
  

WordNet

• (Map Making), a projection of the earth's surface, or any portion thereof, by which each narrow zone is projected upon a conical surface that touches the sphere along this zone, the conical surface being then unrolled. This projection differs from conic projection in that latter assumes but one cone for the whole map. Polyconic projection is that in use in the United States coast and geodetic survey.

Webster 1913

• (Alchemy.), a certain powder cast into a crucible or other vessel containing prepared metal or other matter which is to be thereby transmuted into gold.

Webster 1913

• (Descriptive Geom.), the foot of a perpendicular to the plane drawn through the point.

Webster 1913

• the straight line of the plane connecting the feet of the perpendiculars let fall from the extremities of the given line.

Webster 1913

• noun a white or silvered surface where pictures can be projected for viewing
  screen; silver screen.
  

WordNet

• noun an equal-area map projection showing parallels and the equator as straight lines and other meridians as curved; used to map tropical latitudes
  Sanson-Flamsteed projection.

• the projection of the circles of the sphere upon a plane. See Projection.

Webster 1913

• (Geom.), a method of representing the sphere in which the center of projection is taken in the surface of the sphere, and the plane upon which the projection is made is at right andles to the diameter passing through the center of projection.
