Base Waterbody Polygon Update is the Alberta Environment and Protected Areas base hydrography polygon dataset, it is an updated of the Base Features Hydro Polygons in Southern Alberta from orthophoto and various sources of provincial base data.

Hydro Features is composed of the network of Canadian surface waters. Hydro Features entities are: Watercourse, Water Linear Flow, Hydro Obstacle (falls, rapids\...), Waterbody (lake, watercourse\...), Permanent Snow and Ice, Water Well, and Spring. CanVec is a digital cartographic reference product of Natural Resources Canada (NRCan). It originates from the best available data sources covering Canadian territory, offers quality topographical information in vector format, and complies with international geomatics standards. CanVec is a multi-source product coming mainly from the National Topographic Data Base (NTDB), the Mapping the North process conducted by the Canada Center for Mapping and Earth Observation (CCMEO), the Atlas of Canada data, the GeoBase initiative, and the data update using satellite imagery coverage (e.g. Landsat 7, Spot, Radarsat, etc.).Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

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.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

The MSDI Surface Current Web Service is a dynamic national dataset offering full coverage of surface current visualization in Canadian waters. The service has been developed and managed by the Canadian Hydrographic Service in collaboration with Environment and Climate Change Canada. As with all MSDI products, this service is strictly NOT FOR NAVIGATION. This data is best viewed by software that supports time-aware map services.

High-Resolution Digital Elevation Model (HRDEM) generated from LiDAR. This data collection includes a Digital Terrain Model (DTM) and a Digital Surface Model (DSM). The HRDEM product is referenced to the Canadian Geodetic Vertical Datum of 2013 (CGVD2013). Source data for HRDEM datasets is acquired through multiple projects with different partners. Since data is being acquired by project, there is no integration or edgematching done between projects. The data in this collection have been reprojected from the source reference system to the Canada Atlas Lambert projection (EPSG:3979). **This third party metadata element follows the Spatio Temporal Asset Catalog (STAC) specification.**
