Lakes, Rivers and Glaciers in Canada - CanVec Series - Hydrographic Features
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.Related Products (Open Maps Links):[Topographic Data of Canada - CanVec Series](https://open.canada.ca/data/en/dataset/8ba2aa2a-7bb9-4448-b4d7-f164409fe056)
Base Watersheds
This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. The Base Watersheds data was created by re-working and post-processing the digital elevation data from the Alberta Provincial Digital Elevation Model, the digital hydrography data from the Base Stream and Flow Representation Lines, the Base Waterbody Polygons and the Base Hydrography Point Events and the digital boundaries of the ATS Version 4.1 Alberta Provincial Boundary. The digital elevation data was hydrologically corrected using simplified versions of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons. The digital watersheds were created using the hydrologically corrected filled Alberta Provincial Digital Elevation Model data as a base and the simplified versions of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons as pour points. The routes were created from the raw and simplified versions of the Base Stream and Flow Representation Lines using the names or the longest stream as the base. Strahler Order coding was applied to the simplified version of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons as well as the digital watersheds. Hydrocoding was applied to the routes. The reaches were not created but would be generated using the simplified version of the Base Stream and Flow Representation Lines as a base and the hydrologically corrected filled Alberta Provincial Digital Elevation Model plus the Base Hydrography Point Events to determine the breaks. The Base Watersheds consists of four data packages: Base Watersheds - Hydrologically Corrected Filled Digital Elevation Model (DEM), Base Watersheds - Simplified Hydrography, Base Watersheds - Watersheds and Base Watersheds - Routes. The four data packages are composed of: Base Watersheds Hydrologically Corrected Filled Digital Elevation Mode (DEM) Hydrologically Corrected Fully Filled Terrain Hydrologically Corrected Fully Filled 25 Metre Raster Hydrologically Corrected Fully Filled 100 Metre Raster Hydrologically Corrected Partially Filled Terrain Hydrologically Corrected Partially Filled 25 Metre Raster Hydrologically Corrected Partially Filled 100 Metre Raster Simplified Hydrography Simplified Linear Network Lines Simplified Linear Network Points Simplified Hydropolygons Simplified Linear Network Cross Reference Simplified Hydropolygons Cross Reference Strahler Order Coding Watersheds Fully Filled Watersheds Partially Filled Watersheds Strahler Order Coding Routes Single Line Network Routes Simplified Linear Network Routes Hydrocoding These feature datasets, feature classes and tables were generated using the Base Features Derived Watersheds and Hydrocoding Specifications documents. There are six documents in this collection: Overview Strahler Order Coding Filled Hydrologically Corrected Terrain Watersheds Hydrocoding Reaches Full descriptions of the individual datasets are included in the metadata for the four data packages.
Forest Tenure Real Property Project
This is a spatial layer showing Ministry of Forests Real Property Projects. These are spatial representations of land that is under intensive management/administration by the Ministry of Forests for various purposes consistent with the Forest Act.
Ecoprovinces - Ecoregion Ecosystem Classification of British Columbia
An ecoprovince is an area with consistent climatic or oceanography, relief and regional landforms. There one oceanic, two marine / terrestrial and seven terrestrial ecoprovinces occurring within British Columbia. Ecoprovinces are meant to be mapped at 1:2,000,000 for use in provincial state of the environment reporting
Ontario Hydro Network - Watercourse
Watercourses are line features - natural or manmade - that represent the location of flowing surface water. This product requires the use of geographic information system (GIS) software.
MetNotes
MetNotes are a geo- and time-referenced, free form polygon product issued by MSC that complement today's location-based dissemination systems. The concise text of a MetNote (similar to a Tweet) is consistent with communication today where people are seeking information at a glance. Meteorologists will issue a MetNote to add contextual and/or impact information to complement the public forecast that is valid over a specific area, for a specific time range.
NCC Gatineau Park Land use designations 2021
Described in the Gatineau Park Master plan (2021), the land use designations are the authorized activities or uses in a given area. They support the implementation of the park’s vision and goals. They also ensure that interventions and activities are spatially and functionally consistent. https://ncc-ccn.gc.ca/our-plans/gatineau-park-master-planhttps://ncc-website-2.s3.amazonaws.com/documents/GPMP_ENG_2021_02_26_Single_Page.pdf#page=65
Lot fabric improved
The spatial accuracy of the lot fabric for some townships has been improved through the Ontario Parcel, Township Realignment and Township Improvement projects. Improvements to the fabric may include: * road allowance widths * spatial changes to better represent the location of lot boundaries * more consistent concession names. Data is collected on an on-going basis. The time period "end date" may be more recent than indicated here.
Canadian Hydrospatial Network - CHN
The Canadian Hydrospatial Network (CHN) is an analysis-ready geospatial network of features that help enable the modelling of surface water flow in Canada. The six main layers and feature types are: flowlines, waterbodies, catchments, catchment aggregates, work units, and hydro nodes. Where possible the CHN is derived from high resolution source data such as Light Detection and Ranging (LiDAR) derived Digital Elevation Models (DEMs) and aerial imagery, to name a few. If existing provincial or territorial hydrographic networks meet the standards, they are incorporated into the CHN, otherwise automatic extraction methods are used on the high-resolution source data. To provide full network connectivity, if neither of these methods is possible in a region, the NHN is converted into the CHN until higher-resolution source data is available.Additional value-added attributes are included in the CHN to aid modelling, such as stream order and reach slope. The CHN physical model and features are also closely aligned and harmonized with the USGS 3DHP hydrographic network, which aids trans-border modelling. Where possible geonames (i.e. toponyms) are also added.The CHN is produced and disseminated by hydrologically connected geographic areas called work units. Work units can contain just one watershed, several small adjacent watersheds outletting into a large body of water, or be one of many parts of a larger watershed. In all cases, the features of a work unit are hydrologically connected. This is a more natural approach to data delivery, in comparison to data that is split into tiles. A generalized work unit index file is provided in the downloads to help users decide which files to download.For more information on the CHN please visit the project webpage: https://natural-resources.canada.ca/canadian-hydrospatial-network
TANTALIS - Crown Land Leases
TA_CROWN_LEASES_SVW - A Crown Land Lease is a type of land tenure issued under the Land Act. A Land Act Lease is issued where long term tenure is required, where substantial improvements are proposed, and/or where definite boundaries are required in order to avoid land use and property conflicts. The tenure holder is granted the exclusive use and enjoyment of the area. The tenure holder also has the right to exclude or charge the public for use of the land and/or improvements, when this is consistent with the terms of the lease. Crown Leases require a (cadastral) survey prior to issuance
