GIS

The making and study of maps in all their aspects.

A map that uses charts such as pie charts or bar charts as map symbols.

A map that applies shading symbols to data or statistics collected for enumeration units such as countries or states.

The richness or brilliance of a color. Also called saturation or intensity.

A color model in which colors are specified by the four process colors of cyan (C), magenta (M), yellow (Y), and black (K).

A basic element in map design that enhances the look of a map or the figure-ground relationship by varying the size, width, color, and texture of map symbols.

A display device for a personal computer that uses electron guns and color dots.

A map that uses statistics and additional information to delineate areas of homogeneous values, rather than following administrative boundaries.

A map that uses uniform point symbols to show spatial data, which each symbol representing a unit value.

A tendency in visual perception to separate more important objects (figures) in a visual field from the background (ground).

A map that display different quantities of flow data by varying the width of the line symbol.

A complete set of all variants of a given typeface.

One type of map used for general purposes such as the USGS topographic map.

A map that uses a progressive color scheme such as light red to dark red to show the variation in spatial data.

A map that uses different-sized symbols such as circles, squares, or triangles to represent different magnitudes.

A color model in which colors are specified by their hue (H), saturation (S), and value (V).

The quality that distinguishes one color from another, such as red from blue. Hue is the dominant wavelength of light.

A tendency for an object to appear as though it is behind another because of its incomplete outline.

A map that uses a system of isolines to represent a surface.

The arrangement and composition of map elements on a map.

A display device for a personal computer that uses electric charge through a liquid crystal solution between two sheets of polarizing materials.

The process of developing a visual plan to achieve the map's purpose.

Measurement unit of type, with 72 points to an inch.

A map that uses a specific-sized symbol for each numeric value.

A color model in which colors are specified by their red (R), green (G), and blue (B) components.

Without serif

Small, finishing touches added to the ends of lines strokes in a typeface.

A text string aligned along a curved line.

A map design principle that groups map symbols at the primary and secondary levels according to the intended visual hierarchy.

One type of map that emphasizes the spatial distribution of a theme, such as a map that shows the distribution of population densities by county.

A display tool that controls the percentage of a layer that is transparent.

A particular style or design of type.

Relative blackness of a type such as bold, regular, or light.

Relative width of a type such as condensed or extended.

The lightness or darkness of a color.

The process of developing a visual plan to introduce the 3-D effect or depth to maps.
