Surficial Materials of the Athabasca Oil Sands (in Situ) Area, Northeast Alberta (GIS data, polygon features)
The surficial material dataset was developed as part of the Western Economic Partnership Agreement (WEPA) project covering all of NTS 73M, the southern three-quarters of 74D and southeast part of 84A. Part of the dataset was compiled by airphoto interpretations and followed by random ground-truthing by AGS geologists (NTS 73M). The dataset was later merged with other existing surficial geology maps (74D and 84A). The mapping scheme chosen for the 1:50 000 scale terrain classification is a variant of the scheme used in Alberta Geological Survey Bulletin 57 to map the surficial geology of the Sand River area (Map 178), NTS 73L, directly south of the study area. In this terrain classification scheme, each map unit includes a component of genesis, morphology and relief. Where available, additional information regarding the properties of the genetic unit was included as a genetic modifier. For example, the map unit 'sMh1' denotes hummocky (h), low relief (1), sandy (s) moraine (M). Genesis of geological material is considered to be the primary component of the map unit thus colours on the map depict differences in genesis. In the above example, the map unit colour would correspond to the legend colour chosen for moraine (M). An attempt has been made to reclassify the surficial geological units depicted in the surficial geology map of area NTS 74D (Map 148) using this mapping scheme, without significantly changing the polygon shapes of that previous work.
DND Air Weapons Range
The DND Air Weapons Range dataset is comprised of all the polygons that represent the Air Weapons Range established by the Department of National Defence, Government of Canada, within the Province of Alberta. Air Weapons Range is the area used as a practice and firing range with restricted access provisions and which is owned and operated by the Department of National Defence, Government of Canada.
Bedrock Geological Units, Groundwater Geoscience Program
The bedrock geologic units designate units of the same types of rock which composed the solid rock exposed at ground surface (as outcrop) or which underlies unconsolidated surficial sediments. This dataset represents a general description of the stratigraphy and geology, including geologic unit thickness, morphology, age and rank. It features a list of the geologic unit names and types of rock (lithology) in the hydrogeological unit, from a controlled vocabulary. While the preferred format to deliver this data is by using a shapefile and its linked attributes, this dataset can be delivered also by providing link to external data which should have at least the same properties or also by joining a georeferenced image of the map.
DND Military Base
The DND Military Base dataset is comprised of all the polygons that represent the Military Bases established for the Department of National Defence, Government of Canada, within the Province of Alberta. A Military Base is an area owned by the Department of National Defence, Government of Canada where various military activities occur.
Solar Resource, NSRDB PSM Direct Normal Irradiance (DNI) - North American Cooperation on Energy Information
Average of the hourly Direct Normal Irradiance (DNI) over 17 years (1998-2014). Data extracted from the National Solar Radiation Database (NSRDB) developed using the Physical Solar Model (PSM) by National Renewable Energy Laboratory ("NREL"), Alliance for Sustainable Energy, LLC, U.S. Department of Energy ("DOE").The current version of the National Solar Radiation Database (NSRDB) (v2.0.1) was developed using the Physical Solar Model (PSM), and offers users the solar resource datasets from 1998 to 2014). The NSRDB comprises 30-minute solar and meteorological data for approximately 2 million 0.038-degree latitude by 0.038-degree longitude surface pixels (nominally 4 km2). The area covered is bordered by longitudes 25° W on the east and 175° W on the west, and by latitudes -20° S on the south and 60° N on the north. The solar radiation values represent the resource available to solar energy systems. The AVHRR Pathfinder Atmospheres-Extended (PATMOS-x) model uses half-hourly radiance images in visible and infrared channels from the GOES series of geostationary weather satellites, a climatological albedo database and mixing ratio, temperature and pressure profiles from Modern Era-Retrospective Analysis (MERRA) to generate cloud masking and cloud properties. Cloud properties generated using PATMOS-x are used in fast radiative transfer models along with aerosol optical depth (AOD) and precipitable water vapor (PWV) from ancillary sources to estimate Direct Normal Irradiance (DNI) and Global Horizontal Irradiance (GHI). A daily AOD is retrieved by combining information from the MODIS and MISR satellites and ground-based AERONET stations. Water vapor and other inputs are obtained from MERRA. For clear sky scenes the direct normal irradiance (DNI) and GHI are computed using the REST2 radiative transfer model. For cloud scenes identified by the cloud mask, Fast All-sky Radiation Model for Solar applications (FARMS) is used to compute the GHI. The DNI for cloud scenes is then computed using the DISC model. The data in this layer is an average of the hourly GHI over 17 years (1998-2014). NOTE: The Geographical Information System (GIS) data and maps for solar resources for Global Horizontal Irradiance (GHI) and Direct Normal Irradiance (DNI) were developed by the U.S. National Renewable Energy Laboratory (NREL) and provided for Canada as an estimate. At present, neither the NREL data, nor the Physical Solar Model (PSM) on which the NREL data is based, have been either assessed or validated for the particular Canadian weather applications. A Canadian GHI map developed by the department of Natural Resources Canada (NRCan) is based on the State University of New York (SUNY) model and has been assessed and validated for the particular Canadian weather applications. The Canadian GHI map is available at http://atlas.gc.ca/cerp-rpep/en/.
Linear Landform Features of the Athabasca Oil Sands (in Situ) Area (GIS data, line features)
The dataset was developed as part of the Western Economic Partnership Agreement (WEPA) project covering all of NTS 73M, southern three-quarters of 74D and southeast part of 84A. It contains all the linear landform features such as eskers, flutings and melt-water channels, etc. Part of the dataset was complied by air photo interpretations and followed by random ground-truthing (NTS73M) by AGS geologists. Dataset was then merged with other existing surficial geology maps (NTS 74D and 84A). Analysis of surficial geological materials, aspects of local relief, and morphological characteristics of surface landforms form an integral component in the evaluation of recharge fluxes to regional groundwater flow systems. To assist in the evaluation of groundwater recharge, terrain analysis maps were constructed in GIS format at a scale of 1:50 000 and 1:250 000 for most of the study area, including all of map NTS 73M (Winefred), the southern three-quarters of map NTS 74D (Waterways), and the southeast part of NTS 84A (Algar). Surficial geology maps of the portion of the study area that lies within map area NTS 83P (Pelican) were published by the surficial geology group in the Minerals Section of the Alberta Geological Survey. The terrain analysis maps in NTS 73M and NTS 84A were constructed almost entirely from the interpretation of 1:60 000 scale aerial photographs, supplemented with only a minor amount of ground verification. Terrain analysis maps in the area defined by NTS 74D were constructed from both aerial photograph analysis as well as from published surficial geology information (Bayrock, L. and Reimchen, T., 1973). Classification of the terrain was based on interpretations of landform types, tonal reflections of surface materials, differences in vegetative cover, and differences in drainage patterns and characteristics, all of which can be identified on aerial photographs. It is for this reason that the maps are referred to as aerial photograph terrain analysis maps, rather than surficial geology maps, which generally have a greater amount of ground verification. The reader is therefore cautioned that a higher degree of uncertainty exists regarding the information depicted on the terrain analysis map, compared to that on a surficial geology map.
