WorldMap is an open source GIS tool that enables anyone anywhere in the world to create their own maps and overlay them with data for free. Why did Harvard create this?
GIS has been transformed in the last 20 years. I was using it in a project when I moved up to Harvard from Columbia in the early 1990s. I received some outside funding to put together a GIS mapping system of Africa. When that project came to a conclusion, I applied for some additional funding for innovative computing. At that time, Harvard had established a new Center for Geographic Analysis. They hired a really brilliant young GIS scientist named Ben Lewis, who is a graduate of University of Pennsylvania’s program in urban planning. It was his belief that one could actually put together a system, making it available to everyone using open source technology. This is what became WorldMap.
We began with Africa. The idea was to bring together the best available mapping anywhere in a format that would allow us to overlay different kinds of data. Soon, other people around Harvard began to look at it. From the sociology to the geology to the history departments, other scholars said, “we’d love to do that as well.” And there was serendipity: this was the first large project at the Center for Geographic Analysis. There, lots of people contributed ideas.
