Water files are provided for the mapping of inland and coastal waters, Great Lakes and the St. Lawrence River. These files were created to be used in conjunction with the boundary files.

This dataset comprises a map of inland water bodies in Canada and neighboring regions, as described by Ghayourmanesh et al. (2024). The data are mapped using the Lambert Conformal Conic (LCC) geographic projection with a spatial resolution of 250 meters. The LCC projection is frequently used as a standard projection at the Canada Centre for Remote Sensing (CCRS) (Trishchenko et al., 2016, Trishchenko, 2019). Each pixel value represents a code describing either the probability of inland water presence or land/ocean(sea) mask

There are two types of boundary files: cartographic and digital. Cartographic boundary files portray the geographic areas using only the major land mass of Canada and its coastal islands. Digital boundary files portray the full extent of the geographic areas, including the coastal water area.

The Atlas of Canada National Scale Data 1:1,000,000 Series consists of boundary, coast, island, place name, railway, river, road, road ferry and waterbody data sets that were compiled to be used for atlas large scale (1:1,000,000 to 1:4,000,000) mapping. These data sets have been integrated so that their relative positions are cartographically correct. Any data outside of Canada included in the data sets is strictly to complete the context of the data.

The hydrographic features of the CanVec series include watercourses, water linear flow segments, hydrographic obstacles (falls, rapids, etc.), waterbodies (lakes, watercourses, etc.), permanent snow and ice features, water wells and springs. The Hydrographic features theme provides quality vector geospatial data (current, accurate, and consistent) of Canadian hydrographic phenomena. It aims to offer a geometric description and a set of basic attributes on hydrographic features that comply with international geomatics standards, seamlessly across Canada. The CanVec multiscale series is available as prepackaged downloadable files and by user-defined extent via a Geospatial data extraction tool.

Atlas of Canada National Frameworks data are standardized national coverages of commonly used geospatial datasets at the 1:1 000 000 scale. The Drainage Network Skeleton dataset is comprised of linear features: single line rivers, flow lines within waterbodies and ocean coastlines. Flow lines within waterbodies are virtual linear features representing the hydrological flow through area features (e.g. lakes, rivers and intermittent waterbodies). These flow lines complete the linear network where rivers would run through lakes, permitting hydrologic network analysis and cartographic generalization. This dataset is required for analytical applications. The coastline component of the Drainage Network Skeleton also delineates oceanic islands. The National Scale Frameworks Hydrology data consists of area, linear and point geospatial and attribute data for Canada's hydrology at a national scale. It provides a representation of Canada's surface water features, and data completeness reflects the content of the source, the original Vector Map level 0 (VMAP0) revision 4 hydrographic layers, except where revision editing has been performed. Key value-added characteristics include river flow direction, connectivity and the tagging of geographical name keys to selected rivers, lakes and islands included in the Concise Gazetteer of Canada. The Atlas Frameworks are a set of integrated base map layers which form part of a larger National Scale Frameworks data collection. These data have been compiled at a scale of 1:1 000 000 with the primary goal being to indicate correct relative positioning with other framework layers rather than absolute positional accuracy.

Contained within the 1st Edition (1906) of the Atlas of Canada is a map that shows the mineralogy and locations of mineral deposits for Eastern Canada circa 1906. A line drawn across the map indicates where the Northern, large portion of the Dominion is virtually unprosecuted except along the valleys of the principal rivers, including the Southern, partly prospected areas. Different symbols indicate which type of mineral is located in a specific location. The map includes major cities, rivers, major bodies of water, and some railway systems.

Many mining districts are named on the map, and different symbols indicate which type of mineral are located in a specific location. The map includes major cities, rivers, major bodies of water, and some railway networks crossing into the U.S.

Contained within the 1st Edition (1906) of the Atlas of Canada is a map that shows canals, as well as locations and types of Lighthouses along the St. Lawrence and Great Lakes. In addition, the map also shows sailing routes through those water bodies. There is a table of sailing distances, in geographical miles, between the ports of the United States and Canada on the Great Lakes and St. Lawrence. Statistics of freight and passenger traffic through the canals, total cost of maintenance, and the construction of Canadian canals, are shown as of 1903-1904. There are also steamship routes from Canadian ports to other ports in Canada and in the U.S. The lighthouses are distinguished between fixed, revolving lights, and light ships. The depth of the water of the Great Lakes is indicated by contours and tints of blue. The deeper portions are shown in the darker tints, while lighter tints indicate more shallow waters.

Contained within the 1st Edition (1906) of the Atlas of Canada is a map that shows the network and destinations of telegraph lines in Quebec and Maritime Provinces. More then one line may have followed the same route, but only one line is indicated on the map, especially in larger cities. Therefore, well-settled portions of the country are likely to have more then one telegraph line serving the principal towns along each route indicated. Most telegraph lines are alongside railways. The map includes the routes and destinations of underwater cables. It also indicates the shore portions of the various cable lines, including the Marconi stations on the Atlantic coast of Canada, magnified and placed in the bottom left corner. The map also includes major cities, counties, rivers, major bodies of water and the railway system.

Technical information OIH data is available for the entire province making it possible to create a watershed for any location in Ontario. This includes areas flowing in from neighbouring provinces and Minnesota with the following exceptions:

points on the international border that drain to Lake Superior, south of Pigeon River points on the international border that drain the Great Lakes connecting channels and St. Lawrence River stateside points along the Ottawa River that drain from Quebec.

Special Note: North West package The North West package contains hydrography data for the entire Rainy River Basin, an area which straddles the international border between Canada and the United States.

The data stateside originates from the National Hydrography Dataset (NHD) as of February/March 2014. This data has been harmonized with the Ontario Hydro Network (OHN) to create the Enhanced Watercourse and Integrated Waterbody layers found within the North West package.

Note on new file formats January 2018 The original files for this census were the Esri .e00 interchange format files and the Mapinfo format files. Shapefile and geojson format files suitable for use with newer technology were created using GDAL: http://www.gdal.org/ Specifically, files were converted from Mapinfo: ogr2ogr -f {fileformat} [options] {output file} {input file} Note that some lengthy field names may be truncated. If you wish to use the original files provided by Statistics Canada, please use either .e00 format or Mapinfo format.

This dataset provides 1) a conservative open water mask for future water surface elevation (WSE) extraction from the co-registered AirSWOT Ka-band interferometry data, and 2) high-resolution (1 m) water body distribution maps for water bodies greater than 40 m2 along the NASA Arctic-Boreal Vulnerability Experiment (ABoVE) foundational flight lines. The masks and maps were derived from georeferenced three-band orthomosaics generated from individual images collected during the flights and a semi-automated water classification algorithm based on the Normalized Difference Water Index (NDWI). In total, 3,167 km2 of open water were mapped from 23,380 km2 of flight lines spanning 23 degrees of latitude. Detected water body sizes range from 40 m2 to 15 km2. The image tiles were georeferenced using manually selected ground control points (GCPs). Comparison with manually digitized open water boundaries yields an overall open-water classification accuracy of 98.0%.
