What are multivariate maps used for?

What is a univariate map?

Our focus has been primarily on univariate maps—maps that show only one thematic data attribute. This is a good start, but cartographers often wish to map more than one variable in a thematic map. This is called multivariate mapping.

How do you show multiple variables on a map?

In the Change data menu, click Change data. Click the category you're interested in. Scroll and select the variable you want to visualize on the map. After the first map is created, select the other variable or variables you want to add by checking the boxes next to all of the variables you want to add to the map.

What is a Cartogram map used for?

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.Sep 4, 2017

What is the difference between a bivariate and a multivariate map?

Bivariate analysis looks at two paired data sets, studying whether a relationship exists between them. Multivariate analysis uses two or more variables and analyzes which, if any, are correlated with a specific outcome.Jun 4, 2018

What is multivariate thematic map?

A bivariate or multivariate map is a type of thematic map that displays two or more variables on a single map by combining different sets of symbols. Each of the variables is represented using a standard thematic map technique, such as choropleth, cartogram, or proportional symbols.

What is a multivariate model?

A multivariate model is a statistical tool that uses multiple variables to forecast outcomes. One example is a Monte Carlo simulation that presents a range of possible outcomes using a probability distribution. ...

What is a population density map called?

Choropleth maps are the fancy name given to maps which show information using colour. In the example below, different shades of one colour are used to show the population density. This is the number of people that live in an area.

What is a bivariate Choropleth map?

Bivariate choropleth maps combine two datasets (usually numerical data) into a single map allowing us to show relatively how much of X (variable 1) and Y (variable 2) exist in each enumeration unit. ... Like all bivariate maps, these maps encode two numbers/facts per location and are, therefore, graphically efficient.

When should you not use a cartogram?

When Not to Use a Cartogram

Maps depend on variation in scale to represent a large area and a cartogram is not a true representation of the real-world area and may give incomplete information. One of the disadvantages of the cartogram is that it inevitably changes the visual representation of geography.

How is a cartogram different than a regular map?

Simply put, a cartogram is a map. But a cartogram is a unique type of map because it combines statistical information with geographic location. Physical or topographical maps show relative area, distance, and terrain, but they do not provide any data about the inhabitants of a place.Aug 29, 2014

What is multivariate mapping?

  • So far in this course, we have discussed many different ways of symbolizing data using visual variables. Our focus has been primarily on univariate maps—maps that show only one thematic data attribute. This is a good start, but cartographers often wish to map more than one variable in a thematic map. This is called multivariate mapping.

Can the same data be multivariat-ized?

  • The important thing is to try it and see. 6:42 The same data can be multivariat-ized in lots of ways. Literally a kajillion. 7:15 If you stack up some graduated symbol layers for a multivariate map you definitely will have issues with occlusion (stuff covering up other stuff). Well not if you offset them radially like the petals of a flower.

What are some examples of map types with multiple variables?

  • Choropleths and Cartograms provide two great examples. I gave a talk, long long ago, about some of these map varieties. Most of these more common map types focus on a particular variable that is displayed. But what if you have multiple variables that you would like to present on a map at the same time?
