GE Book - Besavilla Cartography Flashcards
A map used for navigation in air or in water. It is a large special purpose map or diagram.
Chart
A projection on which the shape of any small area remains unchanged.
Equal Area Projection
A sequence of colors usually varying from green to brown, marking zones of elevations between successive contour lines.
Altitude tint
A reference element, such as line or plane: to which the position of other elements are related.
Fix
Any regular set of parallels and meridians upon which a map can be drawn.
Map projection
Any map showing boundaries and subdivisions of a tract of land determined by surveying.
Planimetric
Map projections turned right angles to their usual orientation.
Transverse projection
Unit of length from 10 millionth part of the arc distance between the equator and poles. It is 39.37 inches long.
Meter
Inner border of a map
Neat lines
Pinpoint or crosses, or four sides of the map by which color separation drawings are adjusted to each other.
Register Marks
A group of projections with horizontal parallels and evenly set vertical meridians.
Cylindrical Projections
A projection on which the shape of any small area remains unchanged.
Combination sheet
An imaginary line on the ground, all points of which at the same elevation above a special datum is in direct contact with sensitized sheet.
Contour
A group of projections which are derived from the connect of projecting the parallels and meridians of a globe upon a tangent or secant cone and then developing the cone into a plane.
Conic Projections
A spherical body. In cartography it refers to a small sphere representing the earth.
Globe
A group of projections upon which any area, large or small, is the same as on a globe or corresponding scale.
Equal-area projections
A network of two sets of regularly spaced straight lines intersecting usually at right angles.
Grid
A method of relief representation on maps by short lines which run parallel to the dip of the slope. The steeper the slope the heavier the line.
Hachuring
An organic colloid which swells in cold water and and dissolves in hot water. It is used in most photographic emulsions.
Gelatin
A method of rapid notations of geographic data in a notebook or on maps.
Geostenography
A lune-shaped map to be fitted to a globe.
Globe gore
A map which is sufficiently complete to be given to the engraver or scriber for the preparation of printing plates.
Guide copy
An arc distance from the equator measured in degrees.
Latitude
A drawing of a three dimensional body related to three axes. The dimensions parallel to the axes are true to scale. One of the axes is usually vertical.
Isometric Diagram
A shade between black and white.
Halftone
Small or medium scale map showing the nature of the relief by semi-pictorial symbols.
Landform map
A river or lake which is dry for 3 months or more, on the average.
Intermittent river or lake
The representation of water features on maps.
Hydrography
Lines drawn on maps connecting points of equal value.
Isopleths
Parts of map showing relief.
Hypsography
Explanation of symbols on map
Legends
Printing form the surface of limestone (or kerneled metal sheets) on which the features are drawn with greasy ink or crayon. The stone, if wetted and rolled over with greasy printing ink , will take the ink on the repviously greased surface and repel it elsewhere.
Lithography
It is the shortest distance between points on the earth’s surface which crosses successive meridians at different angles; thus azimuth varies from point to point.
Orthodrome
A line of constant compass direction all along its length
Loxodrome or rhumb line
This will show the for every day of the year the position which the sun shines vertically when the local time is 12 noon on the meridian for which it is drawn.
Analemma
The father of systematic astronomy as well as of mathematical mapping.
Hipparchus
An equirectangular projection and one of the simplest projection composed of an evenly spaced network of horizontal parallels and vertical meridians. This is the only projections in which all loxodromes are shown as straight lines. It is for this reason that most nautical charts are made in this projections.
Cylindrical Projections
On of the most famous and widely used projection which is used as a world map designed for navigation. It is not advisable to carry this projection beyond 70 degrees latitude because of the great distortion. This type of projection is of little use for purposes other than navigation.
Mercator Projections
Projection derived from a tangent or secant cone that can be developed. These are suitable for mapping geographical features which are located in the middle latitudes.
Conical Projections
Type of projection which is derived from a cylinder cutting the sphere at the 45°N and 45°S parallels or the standard parallels of the projection. It shows parallels which are projection. It shows parallels which are projected from the antipodal point on the equator to any meridian. Maps which are made by this projection are useful for showing the distribution of climatic, economic and population data.
Gall Projections
This projection resembles the Mercator projection but shows less exaggeration of area in the higher latitudes. It is widely used in atlases for climatic maps to portray temperatures and barometric pressure distributions, as well as wind flow directions and velocities.
Miller Projections
A type of projection in which the directions of all lines radiating from the center of the map have the same directions as the corresponding lines on the surface of the earth.
Azimuthal Projections
