Collection Overview: The Municipality of São Paulo, through the Municipal Secretariat for Urban Development (SMDU),  is one of the first cities in South America to make its lidar data freely available.  The objective of the Mapa 3D Digital da Cidade (M3DC) of the São Paulo City Hall is to publish LiDAR point cloud data.  The organization has made its lidar collection over Sao Paulo freely available through its Geosampa Portal as well as through the Amazon Web Service Open Data program. The initial dataset was acquired in 2017 by aerial surveying.
