My Cartography
Starting in 1990 as a volunteer for Greenbelt Alliance, I produced some of the earliest computer-based maps documenting the threat to open space. In 1996 Larry Orman and I hatched the idea of GreenInfo Network: mapping and information in the public interest. Through GreenInfo I’ve continued to produce environmental maps. This work is only possible because of dedicated clients and colleagues. I build on the work of others
