Isaac Mustapha and Leticia Makafui made an informative presentation introducing OpenStreetMap (OSM) at Linux Accra User Group's regular Saturday meeting. The presentation walked through its features, an overview of mapping along with hands-on activities. OpenStreetMap is a community-driven project that actively provides and updates map data. This data is open and is used in numerous devices and applications all over the world. The process of adding or contributing this data is known as mapping.
