Context

In October 2014, IGN FI won a tender from the United Nations Development Programme (UNDP) for the creation of a basic digital map of the entire Beninese territory. Since the country's independence, with rare exceptions, the mapping of Benin had not been updated.

The creation of this mapping was part of the Project to Support the Preservation and Development of Gallery Forests and Production of Basic Digital Mapping (PAPDFGC). Co-financed by the European Union as part of the Global Alliance for Climate Change and UNDP, the project also received support from the beneficiary municipalities and the Government of Benin.

This project relied on entirely local production with a strong transfer of skills, driven by IGN FI experts.
