ONEGEO is a Berlin based technology company that provides worldwide building information.
The development team started with OSM Buildings - a free and open source geo spacial 3d viewer in 2012.
The project and its demand for building data grew massively until 2018 when we founded 3dbuildings.
ONEGEO takes care of all commercial aspects, providing data, infrastructure and funding.
We integrate any global data source relevant to buildings in order to create the most comprehensive and clean data set.
