Who We Are?

About the Organization

OpenMap Development Tanzania is a registered NGO based in Dar es Salaam and operating across Tanzania. Since 2017, OMDTZ has promoted a number of community mapping projects, generated map awareness, actively pledged open data sets and continued to build a network of enthusiastic mappers in Tanzania. Similar to other humanitarian organizations like the Humanitarian OpenStreetMap Team (https://www.hotosm.org/), all activities are set up around the global OpenStreetMap (OSM – https://www.openstreetmap.org/)platform, which is both a map and database of geographic data owned by the contributors themselves: anyone is able to view, create and use this information for free. 

OMDTZ staff has been heavily involved in the success of community mapping projects in Tanzania through engaging and training community members to, for instance, map the flood-prone areas of Dar es Salaam for flood resilience under the Ramani Huria project which was a World Bank and DFID funded project. We also involve university students and communities  with different backgrounds ranging from technology, social, economy, political, academia and community members who are the center of our operations.


The organization envisions open-source data and applies this principle to assist the organization and individuals locally and internationally to manage and solve social, economic and community challenges


The organization’s mission is to have a vibrant Tanzanian community that is united, organised, growing to assist and get involved in national and global development goals via mapping.
