Gretchen Peterson is the Founder of PetersonGIS and a pioneering voice in making cartographic design principles accessible to GIS practitioners. She is the author of "Cartographer's Toolkit," "GIS Cartography," and co-author of "QGIS Map Design" (with Anita Graser).
Her books have become essential references for practitioners seeking to improve the visual quality of their maps. "Cartographer's Toolkit" provides practical guidance on color, typography, and layout, while "GIS Cartography" bridges the gap between GIS software capabilities and cartographic best practices.
Through her writing and consulting work at PetersonGIS, Gretchen has helped democratize cartographic design knowledge, showing that beautiful, effective maps are achievable for any practitioner willing to learn fundamental design principles. Her co-authored "QGIS Map Design" has been particularly influential in the open-source GIS community.
