Abstract:
For each dam location provided by the Atlas of Canada 1,000,000 National Frameworks Data, Hydrology – Dams (V6.0) dataset, the linear representationof the damwas produced by 1) extracting the extent from a secondarydata sourceor 2) manually digitizing from remotely sensed imagery. The Natural Resources Canada, National Hydrology Network (NHN) manmade hydrographic entities were usedas the primary source for dam extraction. The NHN manmade hydrography entities included dams as point, line or polygon geometry types. In order to represent all dams as a linear feature, the NHN point and polygon dams were converted to a line. If the dam could not be directly extracted from the NHN or the NHN date was not relevant to the date of dam construction, then manual digitizing was performed from Landsat TM/ETM+ or Google Earth imagery.In bothcases, the dam line segments were ‘snapped’ to the reservoir vertices to ensure that the datasets were topologically correct.Out of the 843 Atlas of Canada dams, there were 26 dams that were not included in the Dams of Canada. These dams were not represented by a NHN feature or could not be seen from available remote sensing imagery.
Purpose:
The Dams of Canada dataset was created as a supplementary dataset to the Reservoirs of Canada. The Dams of Canada are a linear representation of the Natural Resources Canada, Atlas of Canada 1,000,000 National Frameworks Data, Hydrology – Dams (V6.0) spatial dataset and are topologically correct in relation to the Reservoirs of Canada.  The Atlas of Canada - dams were based on a selection of the Canadian Dam Association (CDA) Register of Dams in Canada. The tailings dams and the dams under construction listed in the register are not included in the Atlas of Canada dataset resulting in a total 843 of the 933 dams listed in the CDA Register.
