This map shows the distribution of Aboriginal peoples early in the eighteenth century after a hundred years of Aboriginal-European contact at the time of the French Regime. Ethnohistorical societies are identified on the map by the major linguistic family to which they belong. Ethnohistorical societies are Aboriginal peoples that were known by name and location to Europeans early in the eighteenth century. A linguistic family code identifies each ethnohistorical society on the map and is used to reference specific information for each ethnohistorical society (refer to the Atlas of Canada's 5th Edition map Native Peoples 1740 for the information).
All available bathymetry and related information for Red Deer Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.
The flood extent products are derived from satellite imagery with a system developed and operated by the Earth Sciences Sector (ESS) of Natural Resources Canada (NRCan). This emergency mapping service is activated for large flood events in Canada. Products are generated and distributed in near real time as processed imagery becomes available. NRCan works closely with Public Safety Canada's National Headquarters in Ottawa, Regional offices, and Government Operations Centre (GOC) to define of user needs, technical feasibility and for the coordination of satellite acquisition planning.
An archive of 2D regional seismic and long period magnetotelluric data collected during 20 years of work under the LITHOPROBE project. Data are primarily onshore and cover widespread regions of Canada. Available data types include raw digital data, processed sections, and images of final sections, as well as auxiliary information required for analysis of the data.
All available bathymetry and related information for South Heart Reservoir were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.
This data provides the integrated cadastral framework for the specified Canada Land. The cadastral framework consists of active and superseded cadastral parcel, roads, easements, administrative areas, active lines, points and annotations. The cadastral lines form the boundaries of the parcels. COGO attributes are associated to the lines and depict the adjusted framework of the cadastral fabric.

The layer presents the information on the distribution of eelgrass (Zostera marina) beds in James Bay, Chaleur Bay, Estuary and Gulf of St. Lawrence according to a literature review of documents produced between 1987 and 2009. Additional Information
Eelgrass's inventory was produced according to a literature review of the following documents:
Calderón, I. 1996. Caractérisation de la végétation et de la faune ichtyenne de la baie de Sept-Îles.
As part of the climate change research, data from the SPOT/VEGETATION instrument are systematically corrected for period 1998-2004 and provided in this archive. The VGT archive contains observations acquired by the VEGETATION sensors 1 and 2 onboard SPOT 4 and 5 satellites. Initial data type 10-day S10 composites provided by the Centre National d'Etudes Spatiales (CNES) and pre-processed at the Flemish Institute for Technological Research (VITO) in Belgium in full resolution (1km) were re-projected into standard Lambert conformal conic map projection and further corrected for bi-directional Reflectance Distribution Function (BRDF) effect and cloud contamination. Growing seasons 1998-2004 are presented with twenty 10-day composites from April 11, to October 31.
This is a raster dataset of the thickness of the Paskapoo Formation. It is a derived dataset created by the subtraction of the base of the Paskapoo Formation from the top of the formation, which in the western part of Alberta is also the bedrock topography. The gridded isopach data cover only the undeformed part of the Paskapoo Formation that extends west to the front ranges of the Rocky Mountains. The isopach data do not include those parts of the formation affected by tectonic folding or thrusting.
