30 Maps in November
One map a day on the official themes, mostly about places I know: the Sierra foothills where I grew up, Rainier, Nevada and wherever geocaching has taken me. The drafts are already coming in.
Projects, dashboards and films
The maps that grew into projects: lidar atlases and analyses, dashboards that update on their own, and flyover films.
