This is a measure of the rain accumulated at various rain gauges throughout the City during the rain season, which typically runs from May 1- Sep 30. Readings are taken at 5 minute intervals.

An extent of land covered by, intermittent and permanent, water bodies and watercourses. This includes both parcel bounding and non-parcel bounding occurrences. Includes the natural watercourses as follows: Bow River Elbow River Nose Creek West Nose Creek Fish Creek. This is a generalized version of the data set and is intended for cartographic purposes and faster drawing time.

Administrative grouping of Habitat polygons into Natural areas maintained by Calgary Parks or located on lands under Calgary Parks Stewardship.

These maps provide landfill setback information as defined under the Municipal Government Act (MGA) Subdivision and Development Regulation (SDR) Landfill Setback (Section 13) from a City of Calgary Landfill or Waste Management Facility (WMF). The file contains the landfill setbacks for the following City of Calgary Landfills: East Calgary WMF, Shepard WMF, Spyhill WMF, Blackfoot Landfill, Highfield Landfill, Manchester Landfill, Nose Creek Landfill, Ogden Landfill, and Springbank Landfill. For more detailed information on the landfill setbacks, contact Waste & Recycling Services.

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 dataset makes historical air quality data accessible for various parameters at Calgary monitoring stations. The data is collected by the Calgary Regional Airshed and Alberta Environment and Parks groups. The data is collected via a web service provided by the Alberta Environmental Monitoring, Evaluation & Reporting Agency (AEMERA). AEMERA provides access to historical air quality data at its air quality stations.
Prior to 2011, Alberta used the US EPA's Air Quality Index calculation method, which produces an index ranging from 0 to 500 (with <100 corresponding to "good" (0-50) or "moderate" (51-100) air quality). Since 2011, Alberta has used the Canadian 10-point Air Quality Health Index scale, with calculations augmented to include additional pollutants. Further information on the AQHI calculation is available at: http://aep.alberta.ca/air/air-quality-health-index/AQHI-calculation.aspx

Identifies the plant communities and environments within the Natural areas maintained by Calgary Parks or located on lands under Calgary Parks Stewardship.

Depicts basic components of The City of Calgary's 2007 Environmental Reserve (ER) Setback Guideline policy, including the base setback based on stream order, and the additional setback modifier based on slope. This can be used as a starting point to scope out riparian-associated ER requirements for planned future developments. It can also be used within existing built areas of the city to highlight past lost ER opportunities.
