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).

Using data collected in 2012 and 2013, The City has created this solar potential dataset of all buildings within city limits. The data shows varying degrees of a roof’s solar exposure, on an annual basis, in generalized optimal conditions. The data model used to generate the map takes into account the shape of the terrain and the relative position of building rooftops and structures, existing infrastructure, and tree canopies. It doesn’t take into account weather conditions, such as cloudy days and precipitation that limit a roof’s direct solar exposure. It also does not reflect any new adjacent structures built after 2012 that may obstruct another building’s solar exposure.

The Yield levels are measured as kWh\m2\day. Yield values are interpreted as: Low Yield (0 - 0.87); Low Moderate Yield (0.87 - 1.74); High Moderate Yield (1.74 - 2.61); High Yield (2.61 - 3.48)

The compressed file for download is 3 GB. The uncompressed files are 3.35 GB. Data is arranged in Townships, with 16 GeoTiff image files in total.

The Solar map data is intended for information purposes only and as a preliminary solar opportunity assessment tool. It is not intended to be used as a decision making source of information for solar panel installations.

This data set contains the community-wide greenhouse gas emissions over time. The emissions are broken down by sector (e.g. transportation, waste, etc.), and by emissions source (residential buildings, commercial buildings, on-road transportation, etc).

The impervious surface layer contains polygon features generated from Digital Aerial Survey mapping line work. The layer features represent the various impervious surface types found within The City of Calgary. These features are classified by surface type and description based on the classification and specifications used in the Digital Aerial Survey Program. Additional higher level general surface type classification has been applied to each impervious surface layer feature. To learn more about other DAS products available, visit Digital Aerial Survey.

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.

The Impervious Surface - 1995 layer contains polygon features generated from the 1995 through 1998 Digital Aerial Survey mapping line work. The use of multiple years of DAS updates best reflects the impervious layer as it was in 1995.The Impervious Surface layer features represent the various impervious surface types found within The City of Calgary. These features are classified by surface type and description based on the classifications and specifications used in the Digital Aerial Survey Program. Additional higher level general surface type classification and referencing to the Alberta Township System (ATS) has been applied to each impervious surface layer feature.
