This document discusses open geospatial data, standards, and software. It begins by introducing OpenStreetMap, an open crowd-sourced map of the world. It then discusses how OpenStreetMap data has been used for humanitarian efforts. Next, it outlines several open geospatial data standards and services for finding, rendering, and processing map data. Finally, it promotes open source geospatial software projects like OSGeo Live, an open source geospatial software distribution with over 60 applications.
