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. The open dataset is not strictly 3D. To download 3D buildings data in Multipatch GDB format (0.35 GB), click zipped geodatabase attachment file, or for 3D buildings in CAD file format (1.17 GB), click zipped Autocad file.
The projection is NAD83 Alberta 3TM 114W (EPSG:3776).

Every year in May, The City conducts the Central Business District (CBD) cordon count. The cordon count is performed at ~ 30 locations around the CBD over a four week time period, collecting data on how people travel into and out of downtown Calgary. The CBD cordon circles the downtown with the Bow River to the north and the railway tracks to the south and from 11 Street in the west to the Elbow River in the east. These data represent the total number of persons entering (inbound) and exiting (outbound) at each location, by modes, during a 16 hour time period. This raw dataset is NOT normalized to average weekday. It is a snapshot of the inbound and outbound activity on a single day at these locations and reflects conditions specific to that day such as construction, lane closures, weather, etc. Therefore, data may not be directly comparable between locations or years.
*Attachment is a summary of the inbound and outbound totals and mode of travel.* For additional information on cordon counts, see Central Business District Cordon Count.

The Impervious Surface 2021 dataset is a collection of polygon features derived from Calgary Digital Aerial Survey mapping linework which have been determined as impervious. Impervious surfaces are defined as any material which will seal the soil surface, impede water infiltration, collect solar heat or deprive tree or vegetation roots of aeration. Impervious surfaces effect many aspects of our City, including storm run off volumes, pollutant concentrations and drainage. The City must understand and manage the amount of impervious surfaces carefully to ensure the ongoing health and vitality of the municipality and the environment.

HVAC or Mechanical permits are issued for the installation, addition or alteration of a heating and ventilation system. Permits must be obtained and inspections completed prior to occupying the space the equipment is servicing. If there are any unresolved building code deficiencies or not acceptable outcomes, contact the permit holder for more information or contact 311. See Mechanical Permits for more information.
