In April 2016, our team collaborated with the LABuildings Import Team to import and validate buildings in Los Angeles. This community-managed project aimed to enhance building coverage on OpenStreetMap within the county and to actively involve local cartographers.

In the initial phase, we validated buildings across key areas including Southside LA, the Westside, Central, and Eastside. Subsequently, we facilitated imports in the Southeast region, covering areas such as San Gabriel, Verdugos, and Pomona Valley. Finally, our efforts extended to the Northwest, encompassing LABuildings Import in Antelope and Angeles Forest.

Overall, the project resulted in the import of approximately 2.92 million buildings, with the participation of around 300 usernames/mappers.

In the first phase, 527,823 buildings were imported.
