Data represents surface water occurrence frequency (percentage), which describes the frequency for each grid appeared as water in the 30 years time period of 1991 to 2020. The data covers Canada’s entire landmass including all transboundary watersheds, and is at 30-meter spatial resolution. The surface water occurrence frequency is derived using the surface water model of Wang et al. (2023) from all-available monthly water data observed by the Landsat satellites (Pekel et al., 2016). Here, permanent waters are represented by 100%, and permanent land surfaces by 0%, of water occurrence for a 30-meter by 30-meter grid. References: Pekel, J.-F., A. Cottam, N. Gorelick, A.S.

The Geographic Feature Code Catalogue contains codes and definitions for geographic features captured and mapped by various BC Government Ministries, which are responsible for their definitions. These codes (fcodes) are embedded into geographic data to mark them, as an aid to integrating data from many sources. (WHSE_CORP.CORP_FEATURES)

Water wells where ground water quality samples were collected by the Naquadat Program between 1954 and 1980

Alberta Geological Survey created a coal and coalbed methane (CBM) database to capture and manage CBM data. The database compiles different sources and contains information on 7923 wells (15,200 formation picks, 37,357 coal picks, 495 coal analyses and 363 vitrinite reflectance measurements). From this parent dataset, individual coal zones were evaluated. This record describes the Lethbridge Coal Zone's thickness isopach.

One of the spatial views of the BC WATERSHED ATLAS 50K, which is the digital basemap representation of the aquatic Man-made waterbodies, Wetlands and Double-line Rivers based on the 1:50,000 scale Canadian National Topographic Series of Maps.

In 2014, the Alberta Energy Regulator (AER) initiated a Play-Based Regulation (PBR) pilot project as a step towards implementation of the Unconventional Regulatory Framework. One of the goals of the PBR pilot is to encourage companies in the unconventional play area to work together on plans for surface development to minimize the numbers of facilities and surface impacts. This data set is one of a series created using earth observation imagery to assess surface change caused by energy exploration. The PBR area extends from Twp. 52, Rge. 7, W 5th Mer. to Twp. 70, Rge. 5, W 6th Mer., covering the towns of Edson, Fox Creek, Mayerthorpe, Whitecourt, Swan Hills, and Valleyview. This quality evaluation dataset was produced for 2005 Landsat data to identify possible misclassified areas due to sensor noise, cloud, haze, and cloud shadow. These areas are assigned to 'bad pixels' or value '1' in the quality evaluation dataset.

This dataset is produced for the Government of Alberta and is available to the general public. Note that the distribution contact is different for the general public than for Government of Alberta ministries. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. The Summer Village dataset is comprised of all the polygons that represent Summer Villages in Alberta. Summer Village is a municipality type defined under the authority of the Municipal government Act. The formation of a Summer Village can occur if a majority of the buildings are on parcels of land smaller than 1850 square metres and there is a population of 300 or more. Generally same provisions related to a Village apply to a Summer Village except that in the latter, elections and annual meetings are required to be held in the summer. A Summer Village is the only type of municipality where a person can vote twice in municipal elections: once in the Summer Village and once in the municipality where their permanent residence is located. Summer Villages can no longer be created in Alberta.
