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 31 of the Atlas, Petroleum Generation and Migration in the Western Canada Sedimentary Basin, Figure 19, Lower Jurassic Petroleum System. 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.

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 23 of the Atlas, Cretaceous Cardium Formation of the Western Canada Sedimentary Basin, Figure 4a, Lower Cardium Formation Paleogeography. 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.

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 12 of the Atlas, Devonian Woodbend-Winterburn Strata of the Western Canada Sedimentary Basin, Figure 5, Winterburn Structure. 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 image service contains high resolution satellite imagery for selected regions throughout the Yukon. Imagery is 1m pixel resolution, or better. Imagery was supplied by the Government of Yukon, and the Canadian Department of National Defense. All the imagery in this service is licensed.

Sand bodies within the Sunchild aquifer subcrop over most of its extent, and because overlying Neogene sediment is relatively thin in the western part of the Paskapoo Formation, the unit expresses itself as the present-day topography. Constructing the Sunchild aquifer-thickness map was somewhat problematic because of the difficulty of mapping the step-like distribution and connection of sand bodies that, in places, are laterally adjacent to muddy intervals. The resultant isopach was generated by subtracting the Lacombe Member surface from the Sunchild surface to yield an approximation of Sunchild aquifer thickness. The Sunchild aquifer thickens from less than 50 m in the east to more than 300 m to the west. The apparent great thickness (about 600 to 700 m) of aquifer along the deformation edge southwest of Drayton Valley is interpreted as an area of stacked, coarse fluvial deposits extending from the base of the Paskapoo Formation almost to surface.

[ARCHIVED] This dataset has been archived as it is no longer able to be provided in this manner. For a more current version of this elevation dataset, please refer to https://nsgi.novascotia.ca/datalocator/elevation/ to access the current catalogue of available elevation products. Elevation data (LiDAR) was captured for a select group of 1:2000 scale map sheets located in the District of the Municipality Of Shelburne. This LiDAR data has not been classified and is a raw data record of all the returns from the LiDAR sensor. The nominal point spacing of the returns is 1 point per metre. The area collected is a total of thirty four 1:2000 scale map sheet windows for a total coverage of approximately 95 square kilometres.

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 zone was evaluated. This record describes the McKay coal zone net coal thickness.

This GIS dataset depicts the surficial geology of the George Lake area (NTS84D/SE) (polygon features). The data are created in geodatabase format and output for public distribution in shapefile format.

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. The mapping of insect epidemics, windfalls (trees knocked down by the wind) and ice is produced as part of the ecoforestry inventory of southern Quebec in order to maintain an up-to-date portrait of the forest. It covers the commercial territory of public and private forests in Quebec. The minimum mapping area is 0.1 ha. This portrait is useful, among other things, for evaluating the intensity and extent of damage associated with insects, windfalls and ice. In each case, the mapping represents the loss of forest cover in the form of disturbances ranging from severe (over 75% of dead trees) to slight disturbances (from 25 to 75% of dead trees). The disturbances in this map date back to the beginning of the century (when information is available) to the present day. They are the result of collaboration between the Directorate of Forest Protection and the Directorate of Forest Inventories. The outlines come from forest inventories (first and second decennial inventories) and ecoforestry inventories (third and fourth decennial inventories). Mortality is dated using defoliation layers from the Directorate for Forest Protection. For the epidemic of TBE (spruce budworm), mortality is considered to occur after a succession of five years or more of severe or moderate defoliation. In the case of the surveyor, a single year is enough to decimate a forest stand. The other elements in the layer are dated using LANDSAT imagery, sample plots, and archival documents.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This GIS dataset depicts the drift thickness of NTS map area 84L ( line features). The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.
