This is a composite land cover layer created from multiple City data sources and compiled into a single seamless land cover layer in 2015. The final land cover layer was checked against the City of Calgary’s 2014 air photo at a minimum of 1:4000. Missing and/or overlapping areas were resolved manually and City parks were reviewed at 1:1000 resolution. The land cover dataset informs several City analyses, including a Habitat Condition Rating model to assess natural area park health and a structural wildlife connectivity model, where land cover resistance values act as the difficulty rankings for terrestrial wildlife movement. The dataset can also be used in analyses of open/park space contiguity.

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.
