Once again, it is our favorite November holiday. Its National GIS Day! In the 19 years since the first GIS Day was celebrated in 1999, it is not a stretch to say that GIS and related mapping technologies have changed the world. Maps and spatial analysis help us solve environmental problems, engage communities, and put our data to use to help inform decision-making.
