This aeromagnetic survey was carried out by Novatem Inc. from February 23, 2019 to April 2, 2019. The data were recorded using split-beam cesium vapour magnetometers mounted in the tail booms of two Piper Navajo aircraft. The nominal traverse and control line spacings were 400 m and 2400 m, and the aircraft flew at a nominal terrain clearance of 150 m. Traverse lines were oriented N45°E with orthogonal control lines.

These structure, isopach and zero edge files are part of a series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project. The series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project have been produced using 2 km equi-spaced modified grids generated from Golden Software’s Surfer 9 kriging algorithm. The dataset used to produce each of the maps in this series was created using data from several projects completed by the Ministry (Christopher, 2003; Saskatchewan Industry and Resources et al., 2004; Kreis et al., 2004; Marsh and Heinemann, 2006; Saskatchewan Ministry of Energy and Resources et al., 2007; Heinemann and Marsh, 2009); these data were validated and edited as required to facilitate correlations between the various regional projects. In addition, to minimize edge effects during contouring, the senior author also generated stratigraphic data from wells in adjacent jurisdictions.

This map of the first vertical derivative of the magnetic field was derived from data acquired during an aeromagnetic survey carried out by EON Geosciences Inc. during the period between April 12, 2010 to June 2, 2010. The data were recorded using a split-beam cesium vapour magnetometer (sensitivity = 0.005 nT) mounted in the tail boom of a Piper Navajo aircraft. The nominal traverse and control line spacings were, respectively, 800 m and 2 400 m, and the aircraft flew at a nominal terrain clearance of 250 m. Traverse lines were oriented N45°E with orthogonal control lines. The flight path was recovered following post-flight differential corrections to the raw Global Positioning System data and inspection of ground images recorded by a vertically-mounted video camera. The survey was flown on a pre-determined flight surface to minimize differences in magnetic values at the intersections of control and traverse lines. These differences were computer-analysed to obtain a mutually levelled set of flight-line magnetic data. The levelled values were then interpolated to a 200 m grid. The International Geomagnetic Reference Field (IGRF) was not removed from the magnetic field.

The Ontario Trail Network (OTN) contains geospatial networks of trails in urban, rural and wilderness settings that are managed by a named organization for transportation, recreation, active living or tourism purposes. The OTN relies on data sharing partnerships with local trail organizations and municipal, provincial and federal governments for ongoing updates and maintenance. Trails in the OTN must be: * associated with a named trail organization * intended for free or paid public access * marked and maintained The OTN collection includes two data classes: * Ontario Trail Network segment derived * Ontario Trail Network access points __Ontario Trail Network segment derived__ This spatial dataset represents segments of trails in the OTN. Trail segments define a linear corridor through the natural or urban environment. The corridors may be single segments or form a looping system. The data includes characteristics about each trail, such as: * trail name * trail association * permitted use * description * length Examples of trail types include: * hiking or walking * cycling * cross-country skiing and snowshoeing * paddling and portage * equestrian * snowmobiling, all terrain vehicle and off-road motorcycle * barrier free (wheelchair accessible) * ice skating Some trail networks have official access points. You can find the location of these points in the OTN_ACCESS_POINT spatial dataset. __Ontario Trail Network access points__ This spatial dataset represents the main access points to a trail system that is part of the OTN. This layer should be used together with OTN Segment Derived. Access points can be spatially related to a trail network based on relative location to a trail segment. Not all trail networks will have official access points.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 24 of the Atlas, Uppermost Cretaceous and Tertiary Strata of the Western Canada Sedimentary Basin, Figure 19, Wapiti Isopach. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

This point layer serves as a flag for known and previously reported locations of species of conservation concern in Yukon, as mapped by the Yukon Conservation Data Centre, when viewed at scales beyond 1:160,000. To view the actual mapped locations (polygons) see the Species of Conservation Concern layer, which becomes visible at 1:160,000.

The Cold Lake oil sands area, Township 56 to 69, Range 1 to 11, west of the 4th Meridian, falls within the Lower Athabasca Regional Plan (LARP). As part of Alberta's Land-use Framework, LARP was developed in 2012 to set the stage for robust growth, vibrant communities and a healthy environment within the region. One of its implementation objectives is to balance the economic development of oil sands and impacts on ecosystem and environment. This is to be achieved through enhanced science-based monitoring for improved characterization of the environment and collection of the information necessary to understand cumulative effects. This land classification raster dataset is derived from 2008 Landsat imagery. It contains 13 classes: 0 - unclassified, 1 - exposed land/cut blocks/harvested areas, 2 - water bodies, 3 - transitional bare surfaces, 5 - mixed developed areas, 6 - developed areas, 7- shoal, 8 - shrub land, 9 - grassland, 10 - agriculture areas, 11 - coniferous forest, 12 - broad leaf forest, 13 - mixed forest, and 14- fire scar.

This GIS dataset depicts the surficial geology of the Cleardale Area (NTS 84D/SW)( line features). The data were created in geodatabase format and output for public distribution in shapefile format.
