Here’s a tip about a new, handy cartography resource from Gretchen Peterson (@PetersonGIS on Twitter) enter the e-book “GIS Cartography: A Guide To Effective Map Design”.
Gretchen’s first e-book in the series is Colors For Maps. About the booklet… Colors For Maps is a 40 page booklet in PDF format that contains 30 color palettes specifically chosen for mapping projects. Each palette is visualized in a sample map and in various combinations to make it easy to pick one.
Color formulas are provided in RGB and HEX. The PDF format makes it easy to visualize the colors on-screen as well as to print them out on your in-house machines.
