1) The document assesses the quality and completeness of OpenStreetMap (OSM) road data for four countries in Africa to determine if it can be used to improve an existing global road dataset (gROADS). 2) Various metrics are used to evaluate OSM data for each country, including positional accuracy, attribute completeness, and comparison to the existing gROADS dataset. 3) The analysis finds that only Ghana's OSM road data is comprehensive and accurate enough to replace the existing gROADS data, while the other countries would not provide significant improvements and are more variable in quality.
