aerowest (www.aerowest.de), a company offering areals and geo-related services, has provided OSM with high-resolution pictures of Dortmund (1px = 5 cm) for an evaluation project.

While mappers in Dortmund can correct and extend the map, including especially housenumbers, aerowest is interested to see, if they can profit from such a partnership. Especially the company would like to evaluate if housenumbers and addresses are of higher quality than the commercial offerings.

See Dortmund homepage for more info (most still in German yet).
