Geo-coding project locations
The World Bank uses geo-conding to map foreign aid projects to the specific location of their intended recipients. The Mapping for Results initiative used the UCDP/AidData coding methodology which assigns latitudes and longitudes to project locations while also specifying the geographic precision and scope of the location (such as the city, district, province, country). Small modifications were made to this methodology in order to meet the specifications of World Bank documentation and mapping needs. For more details see the Geocoding Manual (PDF, 2.9 MB).
How locations are determined
The precision of each project depends on the quality of the publicly available project documentation. Sources vary in the precision that locations are reported; sometimes the exact location is named and in other instances the general area is reported. The system of geo-referencing used by the World Bank coordinates in four main location levels, ranging from point locations, through two administrative divisions, to the country level. Nine precision categories are connected to the coordinates for researchers to select subsets of the dataset that contain different levels of precision. When selecting a single project activity, a window will appear including a description of the precision of that location.
What the maps show
- The maps display the number of activities of a given World Bank project. For example, a loan project in health may have several hospital locations, so the project activities layer will show these locations on the map.
- National and budget support projects are not represented in the map but are listed in the dashboard for each country, at the bottom of the page.
The maps include the following broad sectors, and projects are classified into sub-sectors.
- Agriculture, Fishing, and Forestry
- Public Administration, Law, and Justice
- Information and Communications
- Health and Other Social Services
- Industry and Trade
- Energy and Mining
- Water, Sanitation, and Flood Protection
Where the data comes from and how it is verified
- Project locations are drawn from official World Bank project documents, such as the Integrated Safeguards Data Sheet, Project Appraisal Documents, Environmental Assessments. Although this information is publicly available, the Mapping for Results platform makes the information easily accessible and increases transparency and accountability of the projects. In cases where little project documentation or location information is available, World Bank staff who manage the projects are contacted to request additional location information.
- After documents are reviewed and locations are geo-referenced, Mapping for Results communicated with project managers in select countries to request validation of the findings. Staff review findings and either confirm, delete, or add project locations to the ones identified. Based on staff input, Mapping for Results updates the locations to produce the final geo-referenced locations for a project that will be included in the map.
- Not all data has been validated by Task Team Leders (TTLs), may be updated, and be subject to change.
