Historical floodplain boundaries in BC with a descriptive feature name for each floodplain area (i.e., 200-year floodplain, alluvial fan, or nothing/out-of-floodplain). Digitized from hardcopy 1:5,000 Floodplain Mapsheets for each project area

Index outlining historical floodplain mapping areas. Contains links to Floodplain Mapping Reports stored in Ecological Reports Catalogue (EcoCat)

Lines indicating the limits of the historical floodplain boundary study areas in BC. Digitized from hardcopy 1:5,000 Floodplain Mapsheets for each project area

This map locates the areas of high current and low current of the Ottawa and Gatineau rivers. The low-current zone corresponds to the part of the floodplain, beyond the limit of the high-current zone, that can be flooded during a 100-year recurrent flood. The high-current zone that corresponds to the part of a floodplain that can be flooded during a 20-year recurrent flood. The floodplain corresponds to the space occupied by a lake or a watercourse during a flood period within the meaning of the Policy for the Protection of Coastal Shores and Floodplains.

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.**

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) .
