These 3D building shapes are derived from full surface LiDAR by creating roof surface outlines. Exterior walls are projected from the outer edges of the roof outlines to just below the ground surface.

This dataset covers only a portion of the west end of downtown Calgary. To license the city-wide dataset or specific areas of Calgary, please contact the dataset owner.

The download will provide the 3D buildings data in DGN and Multipatch GDB formats. The projection is NAD83 Alberta 3TM 114W (EPSG:3776).
