From Prague to Berkeley to Nairobi to Kyiv, The Geography of Hope tells the stories of optimists who map the world to a better place.

These are the real-life stories of people who turn "where" into better health care, fairer law enforcement, inclusive communities, more nature, greater profits, and smarter national intelligence. All use the most important technology that most people have never heard of: GIS (geospatial intelligence) to improve lives and change the world.
