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, and updated daily.
This data is QA/QC'd on an annual basis at the end of the calendar year at which time some adjustments may be made to the data. Users should keep in mind that data viewed before March 31 of the following year should be considered in a ‘raw’ state and may be subject to change

This dataset makes historical air quality data accessible for various parameters at Calgary monitoring stations. The data is collected by the Calgary Region Airshed Zone and submitted to Alberta Environment and Parks (AEP). The data is delivered to the airdata warehouse, a central repository for Alberta's ambient air quality data via a web service provided by AEP. In this way, AEP provides access to quality controlled historical air quality data at its air quality stations.
In addition to air quality monitoring data, an Air Quality Health Index (AQHI) is calculated hourly at certain monitoring stations. The AQHI is a simple way to interpret air quality conditions: it provides a number from 1 to 10+ which indicates the relative health risk associated with local air quality. The higher the number, the greater the health risk. Further information on the AQHI calculation is available at: http://aep.alberta.ca/air/air-quality-health-index/AQHI-calculation.aspx

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.

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.
