Promoting a data-driven decision making culture in Tanga under living lab initiative, we are complementing the global objective of OSM i.e. to create a free editable geographic database of the world by various mapping activities around the region. The initiative uses local member by building capacity on how to use OSM and contributing to it as well as University Students. These mappings have been putting the missing pieces of the community on the map and addressing challenges they face so far. The usage of GIS data as a tool for community as a decision-making data tool can help in timely action and on-time problem-solving.
