A map related to a topic, theme, or subject of discourse. Also called topical, geographic, special purpose, distribution, parametric, or planimetric maps. Thematic maps emphasize a single topic such as vegetation, geology, or land ownership. Contrast with base map.
A type of map which uses a variety of graphic styles (e.g., colors or fill patterns) to display information about the map's underlying data. Thus, a thematic map of population might show one region in deep red (to indicate the population density in that region is high), while showing another region in very pale red (to indicate the population density in that region is relatively low).
A map designed to provide information on a single subject
a map designed to depict a certain feature, idea or concept in a particular area
a map that is created with a particular purpose in mind, especially to make a point about the spatial pattern of a single phenomenon
a map which visually displays information
A map depicting selected kinds of information relating to one or more specific themes. Examples are soil type, land classification, population density and rainfall maps.
A map representing a specific theme or topic; for example population density, climate, growing season, grain production, transportation routes, oil production.
A graphic display that highlights the geographic distribution of a particular attribute, or relationships among several selected attributes.
A map that illustrates one subject or topic either quantitatively or qualitatively.
A map depicting one or more specific themes, e.g. rainfall or population density.
More specifically known as a 'choropleth map' it presents Indicators held as Rates in varying shades of colour depending on their value to depict spatial patterns. The map classification (or key) is calculated automatically based on the total range for the areas selected. The classification is not based on a national range. This allows you to differentiate between local patterns. The classification used is based on quintiles - there are many other methods such as Equal Internal. Quintile classification is based on the range of all cases (Rates) being divided into 5 intervals or classes. The range of each class is determined by the distribution of all cases in an attempt to get an equal number of cases into each class. You should read the chapter View Results by Map in the Area User Guide which offers more information on creating and interpreting Thematic Maps. The Frequently Asked Questions (FAQs) also include details on map classifications.
A portrayal of some geographic variable or theme, such as land use, geology, or population distribution, by shading or symbolizing areas or map features to represent the value or class of that theme [AntenucciEtAl91
A map depicting one or more specific themes - eg land use, rainfall, land tenure
A class of map showing the spatial distribution of a particular phenomenon in qualitative or quantitative graphic form. The opposite of a base or reference map (which shows only fundamental information about the Earth's surface and are used as a locational reference base for thematic data). Almost any subject that can be expressed as a geographical distribution can be mapped. Examples of thematic map subjects include population, precipitation, vegetation, exploration, and employment.
A map that displays the spatial distribution of a single attribute or a specific topic, such as property assessments, soil types, or crime locations.
A map that provides information about a certain theme or topic. Geographic, topographic, political, population, and land use maps are all thematic maps. hermal infrared radiation Heat radiated by all bodies, including the earth. This radiation is related to the temperature of the object. Sometimes called far infrared or infrared (IR).
A map that symbolizes features according to a particular attribute. Examples include maps displaying businesses as dots of different sizes or colors according to number of employees or, a map displaying census tracts in different colors according to median household income, etc. Used for: Custom Mapping.
A map which communicates a single theme or subject. For example, a population density map and political boundary map are both thematic maps. This contrasts with a topographical map which is a general purpose map containing landscape features such as rivers, roads, landmarks and elevation.
Map showing statistical rather than topographical information about a place e.g. map showing population density or land use.
A map showing information relating to specific themes, such as soil, land-use, population density, suitability for arable crops, etc. Thematic information may be represented as labelled polygons. lines or points, chloropleth maps, isolines, etc.
map that depicts specific themes or sets of information; for example, forest type, land use, historical migration, property ownership, or animal habitat.
A systematic representation of an area normally featuring a single distribution as its map data (eg. population) and for which the base data serve only to help locate the distribution being mapped. In its function it contrasts with a general map.
Map that displays the geographical distribution of one phenomenon or the spatial associations that occur between a few phenomena. Compare with reference map.
A map designed to illustrate a particular theme.
A map that reveals the geographic patterns in statistical data.
A thematic map (also called a statistical or special purpose map) displays the spatial pattern of a theme or series of attributes. In contrast to reference maps which show many geographic features (forests, roads, political boundaries), thematic maps emphasize spatial variation of one or a small number of geographic distributions. These distributions may be physical phenomena such as climate or human characteristics such as population density and health issues.
