ONEGEO

ONEGEO is a German geospatial data company headquartered in Berlin that specializes in worldwide 3D building data. Operating as ONEGEO GmbH, the company aggregates, cleans, and enriches building footprint and 3D building information from more than 40 data sources, then makes it available for commercial use through area-based downloads and an API. Its customers use the data for enterprise analytics, GIS analysis, visualization, and integration into mapping and spatial applications. The company traces its origins to 2012, when Jan Marsch developed OSM Buildings, a free and open-source geospatial 3D viewer. Demand for the underlying data grew rapidly, leading to the founding of 3D Buildings as a company in 2018. As the business evolved and Sebastian Settgast joined as a director, the company formally rebranded to ONEGEO in 2022. Today ONEGEO is managed by Jan Marsch and Sebastian Settgast, with customer support based in Berlin. ONEGEO positions itself as a provider of clean, comprehensive, and trustworthy building data. Its value proposition centers on removing the complexity of sourcing geospatial data: users can search and select any sized area for immediate download, access data via API, and rely on monthly updates and quality checks. The company also offers roof classification for enterprise analytics and enriched coverage for select regions, alongside sample data for evaluation. As a private limited company (GmbH) registered in Berlin, ONEGEO serves a worldwide market. Its data is approved for commercial use, and the company emphasizes its combination of over 40 data sources, monthly updates, and support from a knowledgeable team in Berlin.

ONEGEO's history begins with a side project. In 2012, Jan Marsch developed OSM Buildings, a free and open-source geospatial 3D viewer. The viewer allowed users to explore 3D building models, and it attracted a growing audience. As people used the viewer, demand for the data powering it skyrocketed. That demand created the impetus to turn the project into a business. In 2018, the company was founded as 3D Buildings, with a focus on supplying the geospatial building data that had proven so popular in the viewer. The company was based in Berlin, Germany. Over the following years, the business evolved from a viewer-centric project into a data provider serving commercial customers. A significant turning point came when Sebastian Settgast joined as a director. His background includes studying geoinformatics at the University of Berlin, and his focus at the company has been on searching for and integrating new data sources to keep the ONEGEO database clean and up to date, as well as handling technical support and other operational aspects. To mark the new era, the company formally changed its name to ONEGEO in 2022. Since the rebrand, ONEGEO has positioned itself around a clear mission: to take the confusion and countless variables out of geospatial data sourcing. The company notes that available geospatial data can be overwhelming to navigate, with varying source quality, inconsistent attributes, differing resolutions, and multiple formats. ONEGEO's answer is to aggregate over 40 data sources, clean and check the data, and deliver exactly what customers need through area-based downloads and an API, with monthly updates. The company operates as ONEGEO GmbH, registered at Leipziger Strasse 65, 10117 Berlin, Germany, with business registration HRB 239697 B at Amtsgericht Charlottenburg, Berlin. Its managing directors are Jan Marsch and Sebastian Settgast. ONEGEO serves a worldwide market with data approved for commercial use, and it maintains customer support in Berlin. Its product direction includes enriched coverage for select regions and roof classification for enterprise analytics.
