PROJECT AREA ZONE 1 B U R K I N A F A S O The process starts with District Assembly Consultations. The consultations involve the use of existing District Feeder Roads Maps as reference for sketching in, all the missing roads that are not on the map with the participation of all stakeholders in a mass-mapping exercise REPUBLIC OF COTE I'VOIRE REPUBLIC OF TOGO The output from the consultation is an up-to-date sketch map of all the engineered and unengineered roads in the district.

SUMMARY Zone 1 CONCLUSIONS At the end of the survey: Engineered Roads Partially Engineered Roads Non-Engineered Roads TOTAL 8,814 km, 1011 km 1879 km 11,703 km GPS/GIS/RS are essential tools for capturing, updating and visualizing road network data for efficient road maintenance planning and management GIS provides the platform for the creation and manipulation of a spatial database for visualizing road attributes such as, surface type, surface condition, traffic volume and any other road related attributes The participation of local people in the capture of road related data is essential for ensuring data integrity Confidence Builders in Resources Management Information Systems Thank You. 5
