[gis_info] Mastering Class Definitions in ArcGIS Pro for Impactful Graduated Color Maps

[Eric Pimpler]

Graduated color maps are a type of thematic map used to represent the
spatial distribution of numerical data across a geographic area. These maps
apply varying shades or colors to areas (such as regions, countries,
states, or counties) to indicate different values or intensities of a
particular variable. The variable in question can be anything measurable
across the map area, such as population density, income levels,
temperature, or precipitation.

The “graduated” part of the term refers to the method of classifying the
numerical data into ranges or classes, with each class assigned a specific
color or shade. The colors usually follow a gradient, moving from light to
dark or through a color spectrum to represent increasing or decreasing
values. This gradient helps to visually convey how the variable changes
across the map, allowing for easy comparison between different areas.

In this article, we’ll explore the different techniques available in ArcGIS
Pro for establishing the classes used in graduated color mapping. The
following examples focus on visualizing the ratio of housing expenses to
household income at the county level. More precisely, we’re illustrating
the proportion of homeowners with mortgages spending more than 50% of their
income on housing costs for the year 2022.
