A map with areas colored or shaded such that the darkness or lightness of an area symbol is proportional to the density of the mapped phenomena or is symbolic of the class.
shows differences between areas by using colors or shading to represent distinct categories of qualities (such as vegetation type) or quantities (such as the percentage graduating from high school, population density, or birthrate).
a two-dimensional map that uses color and fill pattern combinations to represent different categories or levels of magnitude.
a map divided into regions that are shaded according to the value of a variable for that region
a map involving statistics shown in scale using colors, such as population densities, or GNI per capita
A type of thematic map in which the colors (or shades of gray) of area features represent categories of attribute values.
Thematic map, such as a yield image, where quantitative spatial data is depicted through the use of shading or color variations of yield ranges.
A theme-based map using data shaded proportionally to density. The darker the shading is usually indicative of higher values.
A choropleth map is a map which shows regions or areas which have the same characteristics. Each area (county) is shaded according to the data. Technically, a choropleth map is based on a stepped statistical surface.
A systematic representation in which colour or shading is applied to areas bounded by statistical or administrative limits.
a map portraying properties of a surface using area symbols. Area symbols usually represent categorized classes of the mapped phenomenon.
A choropleth map (Greek χωÏα, area, region + πληθαίνω multiply) is a map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. It provides an easy way to visualize how a measurement varies across a geographic area. Choropleth is often misspelled as chloropleth -- with an extra L -- because it is mistakenly assumed that the name of the map refers to its use of color.
