Projections Matter, Especially on Election Night
The first thing I teach someone about maps is that they are more than just lines and direction on a page, screen, or device. Maps convey information. Maps tell a story. But maps can also be deceiving. Consider for a minute, election maps. If you’re reading this blog post then you survived, if just barely, […]

Light Nights
Is light pollution high on your list of concerns? With so many disturbing developments happening globally, light pollution probably doesn’t hold a candle to your worries about accelerating climate change, failing governments, or spreading superbugs. Nevertheless, we are learning more about the impacts of light pollution and there are people in many fields including ecology, […]
Just Take a Screenshot!
At CLEAR, we work hard to provide geospatial data so that most everybody can view and access the maps and information. Inevitably, it is never exactly what everyone wants (sigh, I wish it was). One question that I am repeatedly asked is about printing or exporting. How do I print just one area of a pdf? […]
