This dataset contains results for the City of Calgary's Watershed Monitoring Program. The program monitors surface water quality across a network of sites that include rivers, tributaries, and reservoirs within the Calgary region. Sampling locations have been added, removed, or modified over time. Grab sampling methodologies are used for sample collection.

The City of Calgary uses approved and documented analytical testing methodologies, and the City of Calgary laboratory is accredited to the ISO/IEC 17025 standard. Quality Assurance programs track and ensure consistent laboratory performance. Changes in data over time, such as method detection limits, accredited testing parameters, and formatting are the result of newer analytical techniques and improved data quality standards.

The Development Permit Public Notices data set consists of development permits which have been made public. The City of Calgary is required by law to publish Development Permit information for two weeks.

This dataset demonstrates an optimal size of PV system to be installed on a rooftop area. It is an analysis of residential rooftops (excluding apartment complexes) to estimate a potential capacity of a PV installation. The analysis uses LiDAR data taken in 2018 to estimate solar irradiance and roof shape to estimate the number of 1m x 2m solar panels. This data is then used with PVWatts API created by NREL to estimate the annual AC generated per panel. Each address has one or more entries each representing a continuous area where panels could be installed.

A highly accurate elevation dataset of ground surface topography, derived from aerial Light Detection and Ranging (LiDAR). This 2m resolution version of the bare-Earth LiDAR DEM can be used for a wide range of applications such as 3D spatial analysis (slope calculations, profile creation, volumetric computations), engineering applications (land developments, road design, flood modelling) and 3D terrain visualizations, just to name a few. To learn more visit, https://www.calgary.ca/cs/iis/mapping-products/digital-elevation-model.html or view the attached metadata document.
DEM of 1m and 20cm resolution are also available on Cityonline.calgary.ca

The compressed file for download is ~ 0.5 GB. The uncompressed files are ~ 4 GB and in ESRI ArcGrid ASCII (.asc) file format.
