Mapping Data with QGIS

My Fall 2016 column describes how to get started with QGIS, a free and open source geographic information system.

QGIS is available for Linux, OS-X, and Windows platforms. See the article and the links above for information on installing in. The the article, I built maps using data from the U.S. Census Bureau and other agencies. The data displayed on the maps came from TVStudy 2.0 and PNG map overlays created using the SPLAT propagation software and the Python programs I described in previous articles. To make it easier to get started with QGIS, I've made copies of the map and data files referencd in the article available for download from this file directories below. In the directory listing, click on the small down arrow to download the file. The map layer styles can be customized to improve the map appearance. See the article for information on how to load styles.
