This dataset is collected by the Calgary Region Airshed Zone (CRAZ) and submitted to Alberta Environment and Parks (AEP). AEP provides access to air quality data at its air quality stations. The near real-time data has not had quality assurance processes completed for it. Please use at your own discretion.

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.

(Note: Updated inundation maps for 1:2 to 1:1000 floods are available from Alberta Environment and Parks (2020). The new draft maps can be viewed here: https://floods.alberta.ca/?app_code=FI&mapType=Draft)
These inundation maps show whether a property is at risk for various sized river floods. The size of flood shown on this map has a 1/500 or a 0.2% chance of occurring in any year.
The three distinct types of inundation shown on the maps are:
o Inundation - Area flooded overland due to riverbank overtopping.
o Isolated - Low lying areas that will not be wet from riverbank overtopping, but may experience groundwater seepage or stormwater backup.
o Protected - Area protected by a permanent flood barrier.
The flood areas shown are based on Alberta Environment and Parks most recent (2020) inundation maps. There is uncertainty inherent in predicting the effects of flood events, and this uncertainty increases for floods with less than a 1% chance of occurrence in any year. Any use of this data must recognizing the uncertainty with regards to the exact location and extent of flooding.

This dataset is compiled from The City of Calgary’s in situ (in location) water quality monitoring program. In situ field measures are acquired from the deployment of unattended multi-parameter sondes in surface waters by The City of Calgary.

This dataset consists of the monitoring locations. For the data collected, please see: https://data.calgary.ca/Environment/Water-Quality-Monitoring-Sonde-Data/kc8x-fu3f/about_data

Using data collected between 2012 and 2017, 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 4.25 GB. The uncompressed files are 4.5 GB. Data is arranged in Townships, with 18 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.

Depicts recommended riparian area management category zones along the major rivers and streams of Calgary. These categories are meant to guide land use planning, park management, and river engineering decisions. The spatial mapping of these categories also complements the Riparian Decision Matrix for River Engineering Projects, with the purpose of ensuring bioengineering practices are applied to the maximum extent feasible within The City of Calgary.

This dataset is derived from BenchmarkYYC and contains annual, aggregated building energy and emissions data categorized by primary property type. All energy and greenhouse gas emission metrics are calculated by ENERGY STAR Portfolio Manager.

All cells containing zeros signify that zero is the calculated value for that cell. All blank cells represent data points that are "not available" because they do not exist or cannot be calculated.”

The energy and emissions data fields that are collected are subject to change each reporting year.

Filter by Parameter to change comparisons. Median values are displayed.
