The MapGive initiative is a State Department project designed to increase the amount of free and open geographic data in areas either experiencing, or at risk of, a humanitarian emergency. To accomplish this, MapGive seeks to link the cognitive surplus and good will of volunteer mappers who freely contribute their time and effort to map areas at risk, with the purchasing power of the United States Government (USG), who can act as a catalyzing force by making updated high resolution commercial satellite imagery available for volunteer mapping. Leveraging the CyberGIS, a geographic computing infrastructure built from open source software, MapGive publishes updated satellite imagery as web services that can be quickly and easily accessed via the internet, allowing volunteer mappers to trace the imagery to extract visible features like roads and buildings without having to process the imagery themselves. The resulting baseline geographic data, critical to addressing humanitarian data gaps, is stored in the OpenStreetMap (OSM) database, a free, editable geographic database for the world under a license that ensures the data will remain open in perpetuity, ensuring equal access to all. MapGive is built upon a legal, policy, and technological framework developed during the Imagery to the Crowd phase of the project. Philosophically, these projects are grounded in the open source software movement and the application of commons-based peer production models to geographic data. These concepts are reviewed, as is a reconception of Geographic Information Systems (GIS) called GIS 2.0.
