Digital mapping and GIS-driven feeder road network database management system for road project planning and implementation monitoring in the feeder road sector
Mensa, Martin ... [et al.]
The Feeder Road Sector of the Economy is one of the key correspondents of Ghanaas Growth and Poverty Reduction Strategy. The Department for International Development (DFID) is supporting a comprehensive GIS-mapping in which every kilometer of both engineeredd and non-engineeredd feeder roads are to be chained and the conditions described. The attributes to be described include bridges, culverts, road surface drainage, and social economic infrastructure along the roads, e.g. markets, schools, clinics, etc. The project is being implemented in three zones: Zone 1 covers Central, Eastern, Greater Accra and Volta Regions; Zone 2 covers Western, Ashanti and Brong Ahafo, while Zone 3 covers the three northern regions. In each administrative region the feeder road network is being organized into administrative district level network. The district network will however be joined together into the regional network and the region be joined to have the national feeder roads network in GIS-format. The database is being structured such that each road segment has its district and regional codes to which is linked the various attributes. Georeferenced to the Survey Topographic map (1/50,000 series) the database will harmonize with the other databases being structured and harmonized in GIS environment. The presentation focuses on work done in the Zone 1 of the Project.
