How to create a color coded map

A color coded map is a visual tool that uses different colors to represent data values across geographic regions, such as zip codes, sales territories, or districts. This type of map makes it easy to spot patterns and compare performance based on geographic data, especially when combined with our business mapping solutions.

With a color coded map, you can:

• Instantly visualize trends across territories or regions
• Identify underperforming areas or gaps in coverage
• Support data-driven decisions for marketing, HR, or sales planning

eSpatial's color-coded maps are especially useful for spotting geographic disparities at a glance, making complex datasets easier to interpret and act on.

Simple color-coded maps should not be confused with heat maps, which use graduated colors to express values within a region. You'll find a good description of heat maps here, and for more information, check our thematic mapping guide.

Follow these best practices to make sure your maps are clear, accurate, and easy to read:

• Keep it simple: Don't overload your map with too many colors or categories
• Use meaningful colors: Choose colors that make sense to your audience (e.g., warmer colors for higher values, cooler for lower)
• Maintain contrast: Pick colors that stand out from each other so patterns and differences are easy to see
• Add a clear legend: Always include a legend explaining what each color means
• Test your map: Share it with colleagues or stakeholders to check if the story it tells is immediately clear

Knowing how to create a color coded map lies in balancing clarity, design, and the right choice of colors to tell your story at a glance. With eSpatial's easy-to-use GIS mapping software, you can bring your data to life and create maps that look as professional as they are practical.
