Yaounde, Cameroon

The Government of Cameroon through the Inclusive and Resilient Cities Development Project (IRCDP), is working with the World Bank to improve urban management, access to infrastructure, and resilience to natural hazards in several cities. IRCDP aims to integrate climate change adaptation and disaster risk management into development planning and strengthen the capacity of academics and professionals to support planning for resilient development.

In Yaoundé's Municipalities 5 and 7, the SOGEFI - IRD consortium will : i) design and facilitate the implementation of a risk understanding curriculum comprising several block courses in close collaboration with local universities; ii) in collaboration with the OpenStreetMap Cameroon association, ensure the collection of existing and new data on disaster risks, including exposure data; iii) produce flood risk maps based on the results of flood modelling; and iv) provide technical assistance to integrate risk information into urban land use plans and urban development projects in Yaoundé.

Mapping Progress to Date

This section provides an overview of mapping activities in the selected city geographic extent. The Before/After widget below allows comparing current density and distribution of map features with snapshots from previous years. The time chart of OSM editing activity over time offers insights on how many features have been contributed to the map over a specified period.

Data Quality

While OSM coverage keeps increasing, it's important to also understand quality of the data created. The tools available in this section allow for comparing OSM data with other "reference" datasets. These could be, for example, official datasets from government agencies showing distribution of features with those available OSM. The "Gap Detection" widget provides a visual representation of potential gaps in data, by comparing the latest OSM buildings with built-up areas automatically detected from satellite imagery.
