Gretchen Peterson

Gretchen Peterson’s most recent books are City Maps: A Coloring Book for Adults and QGIS Map Design. Peterson resides in Colorado and actively tweets via @petersongis on cartography.

A Cornell graduate in the natural resources field, Peterson can still be found spending part of the workweek absorbed in data analysis and mapping for the greater environmental good while reserving the rest of the workweek for broader mapping endeavors, which includes keeping up on the multitude of innovative map styles coming from all corners of the profession.

Peterson speaks frequently on the topic of modern cartographic design, and it was in one of these talks that the Ye Olde Pubs of London’s Square Mile map was not only shown off but also created on-the-spot as a live demo of the cartographic capabilities of the QGIS software. The FOSS4GNA 2015 conference talk went through the process of loading and styling data and then creating a print composer map layout.

Some highlights of the demo included the custom pub data repository created just for this map, the demonstration of the relatively new shapeburst capabilities of QGIS, and the technique for modifying image file (SVG) code in order to allow icon colors to be changed within the QGIS interface.

The map was also the focus of a QGIS cartography workshop held in Boulder, Colorado. The students at that workshop followed the instructions posted on github to create the map. It’s a great two-hour project for introducing the software and a few of the principles of cartographic design, and readers are encouraged to give it a try and supply any feedback you may have.
