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.

This dataset has the following 11 columns:
| Column Name | API Column Name | Data Type | Description | Sample Values |
|---|---|---|---|---|
| Quadrant | quadrant | text | City of Calgary Quadrant (NE, NW, SE, SW) | NW NE SE SW view top 100 |
| LC_CAT | lc_cat | text | Land Cover Category (Agricultural_Annual Crops, Agriculture_Pasture/Fallow, Bare Ground, Building/Paved, Construction, Forest, GolfCourse, Grassland, Manicured, Natural Wetland, Paved Trails, Reservoir, Roads/Raillines, Shrubland, SportFacility, Storm ponds/Modified Wetlands, Stream/Rivers) | Building/Paved Manicured Roads/Raillines Forest Grassland view top 100 |
| ASSET_CD | asset_cd | text | Park Asset Code, if land is stewarded by Calgary Parks (null, if not); asset codes are shared with other Parks layers | GPK056 BRD099 NPK454 SIL245 GPK120 view top 100 |
| PkScMetric | pkscmetric | text | Partially generalized set of fields from LC_CAT (Ag_Crops, Ag_Past, BareGrd, Impermeable, Mowed, NatCover, SportFacility, StormPond) | Impermable Mowed NatCover BareGrd SportFacility view top 100 |
| LdScMetric | ldscmetric | text | Most generalized delineation of Calgary lands through a spectrum of 'naturalness' (NatCover > Permeable > Storm Pond > Impermeable) | Impermable Permeable NatCover StormPond view top 100 |
| Resist | resist | number | Land cover modification scores (i.e. the deviation from 'natural') for each LC_CAT (land cover category). Higher scores indicate greater intensity of human modification to land: Streams/Rivers, Natural Wetland/Shrubland/Forest/Grassland = 0.05; Manicured, Paved Trails, Agriculture_Annual Crop, Agriculture_Pasture/Fallow, GolfCourse = 0.25; SportFacility, Reservoir, Storm pond/Modified Wetlands = 0.5; Bare Ground, Building/Paved, Construction/Roads/Raillines = 1 | 1.0 0.25 0.05 0.5 view top 100 |
