Make your map more useful
Approximately 300 million people—or 4.5% of the global population—have a form of color vision deficiency (the inability to distinguish certain shades of color). Complex maps that depend exclusively on color to symbolize categorical data can be frustrating, if not impossible, to read.
According to Designing Maps for the Colour-Vision Impaired by Bernhard Jenny and Nathaniel Vaughn Kelso:
To avoid problematic colour combinations, the cartographer should use colours with strong contrast and supplemental visual variables, such as shape, size, and pattern variations to allow all readers to discern and directly interpret a symbol without consulting a legend"
TextureMap gives you everything you need to start adding textures, patterns, and shapes to your maps in minutes.
