The Exploratorium in San Francisco features a large space dedicated to geospatial mapping, interactive maps, and activities that tell stories about the world around us. The museum's 3D relief map of the San Francisco area is installed with a top-down projector, allowing for the creation of new interactive maps. Visitors can plug in their laptops and use tools like CartoDB to create beautiful data visualizations on the 3D surface. The Exploratorium's exhibit showcases the power of mapping technology and its potential for creative storytelling.
