Tree Canopy contains polygons outlining the extent of tree cover for all land within the City of Calgary. The tree canopy was derived by Remote Sensing software using City of Calgary Orthophotos and Lidar. The resulting data was then quality controlled and edited using various photogrammetric and processing tools.

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 Regional Transportation Model (RTM) is a computer simulation of the city and surrounding region. This file contains the road network assumptions for the 2015 Scenario from the 2015 CTP/MDP Scenario Series. This series is a time series of future forecasts that are used in transportation planning analysis. The series contains five horizons from 2015 to 2076 and includes roads classified as collector and above and does not include local roads. his data is a representation, not an exact replica, of the road network and is intended to represent the road network that Calgary Region residents may experience provided the anticipated changes in infrastructure and land use occur. For more information see the Transportation Forecasting website: www.calgary.ca/forecasting. Versions: 2015 Horizon: 092618; 2028 Horizon: 092618; 2039 Horizon: 101118; 2048 Horizon: 101118; 2076 Horizon: 092718.

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.
