The OneMap Initiative, its concept was born in FOSS4G 2018 in Dar es Salaam, has been established to improve or produce and share geospatial information data over the countries, where accurate and up-to-date geospatial information is not available or insufficient, in a coordinated/cooperated manner through the development of common framework, including common operational geodatabase, among the participating organizations. The aim of the OneMap Initiative is to create and operate a suitable and sustainable mechanism on joint production and sharing of geospatial information for various stakeholders to work closely together as One team in order to avoid duplication of efforts and resources and to synchronize and integrate them within a streamlined approach for a maximum benefit to all. Together with the Geo-referenced Infrastructure and Demographic Data for Development (GRID3) initiative, OneMap pilot project in South Sudan is being implemented.
