Chapter 3 - Part 3: Other Map Types
The last part of chapter 3 covers other map types, specifically cartograms and flow maps.
Cartograms are maps that distort the area and shape of countries (or other units) based on an attribute. They resize and exaggerate any variable on an attribute value. Read more details about cartograms on the GISGeography website.
There is no one button click tool in ArcGIS Pro to create a cartogram, but there are ways to create one using multiple steps.
A great resource for cartograms related to many different attributes can be found on the World Mapper website.
3.5: Flow Maps
Flow Maps are a type of thematic map used in cartography to show the movement of objects between different areas. Read more details about flow maps at the websites below:
Flow Maps are described on GISGeography.com. It's possible to create flow maps in ArcGIS Pro using the spatial analyst extension. And starting recently, it's possible to create them in ArcGIS Online as well.
3.6: Bivariate Mapping
Bivariate mapping (also called relationship mapping) is a unique way to display two attributes at once. This article describes how to create one in ArcGIS Online.
Chapter 3 covered thematic maps: choropleth, proportional symbols, dot density maps, cartograms and flow maps.
