What is a cartogram map for kids?

A cartogram is a map in which the size of a region or territory is in proportion to data the map shows, whether it’s land area, population, or amphibians.2014-10-21

What is a cartogram and how do geographers use them?

A cartogram (also called a value-area map or an anamorphic map, the latter common among German-speakers) is a thematic map of a set of features (countries, provinces, etc.), in which their geographic size is altered to be directly proportional to a selected ratio-level variable, such as travel time, population, or GNP.

How does a cartogram work?

A cartogram is a map in which the geometry of regions is distorted in order to convey the information of an alternate variable. The region area will be inflated or deflated according to its numeric value.

What is a cartogram in simple terms?

Definition of cartogram : a map showing geographically diagrammatic statistics of various kinds usually by the use of shades, curves, or dots.

What does cartogram mean in geography?

1. Definitions. cartogram: a diagrammatic map type that represents the mapped area by distorting the geometry of the feature itself. non-contiguous cartogram: adjacencies are compromised as areas shrink or grow; individual area shapes are preserved but they become detached from the overall map.2017-09-04

When should you use a cartogram?

Use a cartogram when you need to represent an area in the context of the value a variable associated with it holds, making it useful as an isodemographic map.

When would you use a cartogram map?

Cartograms are used for thematic mapping. They are a particular class of map type where some aspect of the geometry of the map is modified to accommodate the problem caused by perceptually different geographies.2017-09-04

When should you not use a cartogram?

1When required to make statistically accurate trade-off decisions. Do not use cartograms when balancing statistical accuracy, geographical accuracy and topological accuracy are of importance to you.

What are the disadvantages of mapping?

All maps have distortions because it is impossible to represent a three-dimensional objects like the earth accurately on flat maps. Maps with no scale give a poor idea of distances and maps with no legend are frequently confusing to the user.2018-07-31

How do geographers use cartogram maps?

Cartograms tackle this by modifying the geography, effectively normalizing it to create a map where each area takes on a new shape and/or size based on the variable being mapped. Cartograms therefore depict geographical space diagrammatically as they lose their relationship with true coordinate system geometry.2017-09-04

What are the different types of cartograms?

There are four main types of cartogram which each represent the mapped variable differently non-contiguous, contiguous, graphical and gridded.2017-09-04

What is a cartogram map AP Human Geography?

cartograms. Definition: A map in which a certain variable (such as population) is replaced by land area or distance, and the space of the map is altered in order to accommodate this new variable. Example: A cartogram can show the populations in the individual cities of a particular formal region.

What is a cartogram on a map?

Definitions. cartogram: a diagrammatic map type that represents the mapped area by distorting the geometry of the feature itself. non-contiguous cartogram: adjacencies are compromised as areas shrink or grow; individual area shapes are preserved but they become detached from the overall map.2017-09-04

What is the difference between a cartogram and Choropleth?

Choropleth maps show us how much geographic area is affected. On some maps, this means that large regions where only a few people take up a lot of space on the screen. Population cartograms, on the other hand, drive more attention to populated areas.2021-01-04

Why are cartogram maps distorted?

Cartograms exaggerate the size of the geography proportional to the statistic being shown. Specifically, the variable substitutes land area or distance. But what they do is really distort our view of mapping by breaking the golden rule sacrificing geometry to convey information.2021-06-08
