Flood extent polygons from past years in selected Canadian regions that have been designated for observation, monitored by Natural Resources Canada using satellite imagery for emergency response. Coverage is not comprehensive nationwide. In response to large flood events, Natural Resources Canada (NRCan), for the provision of emergency geomatics services, may be activated by Canada’s emergency management protocols. As new satellite imagery becomes available, NRCan will extract flood extent polygons and update the dataset in near real time (4 hours). This item contains the complete archive of all flood products generated since 2005, by NRCan's emergency geomatics services. For any data to the current year, please refer to the catalogue entry entitled: [Floods in Canada – Current]( https://open.canada.ca/data/en/dataset/b1afd8d2-6e14-4ec4-9a09-652221a6cb71). The flood products generated are validated on a best effort basis. Various factors may affect the quality of the flood polygons. These factors include, but are not limited to, sensor type, image resolution, cloud cover or limitations of the flood polygon extraction method. In this layer, where possible, a symbology is applied to the flood polygons based on the underlying land use classification, or is simply unclassified and shows the raw flood extent. When using Web mapping services, to display a specific product, filter by date (UTC Date) and area of interest (AOI). Also, a link to download each product directly from the FTP site is available in the Resources section. This prepackaged and compressed product contains a Shape file, a PDF file and a KMZ file. For more information on past flooding events, please refer to the catalog entry entitled: [Historical Flood Events (HFE)](https://geo.ca/flood-mapping/flood-map-gallery/historical-flood-events/) Disclaimer: Emergency response authorities are the primary users of these satellite-derived open water flood extent map products. These products are generated to provide analysis and emergency response situational awareness and to facilitate decision-making during major flood events. The open water flood extent products are generated rapidly and limited time is available for editing and validation. The flood products reflect the open water flood conditions at the date/time of acquisition. While efforts are made to produce high quality products, near-real time products may contain errors due to the limited time available for vector editing and validation. Please note that current algorithms do not map flooded areas under the forest canopy and are not optimized for urban flood mapping.

Wildlife Key Areas (WKA) are locations used by wildlife for critical, seasonal life functions. WKAs are identified by interpreting observed locations of wildlife at key times of year, not through intensive habitat assessment. Polygons derived from interviews with locals and from GIS interpretation of wildlife/habitat surveys. GIS interpretation follows criteria specific for taxon and/or populations of taxon. Key Areas are based on observed locations of wildlife at key times of year, not on habitat assessment. With new information, boundaries and designations of Key Areas can change and additional Key Areas can be identified. Furthermore, Key Areas are not the only sites important for wildlife. Other information sources can identify other sites important for wildlife for reasons outside the scope of the WKA Inventory Program. Updates to Key Areas occur only periodically. For the most current information, please consult with the Regional Biologist for your area of interest. If you have questions or would like to contribute to the WKA database, please contact the WKA Inventory Program ( [wka@yukon.ca](mailto:wka@yukon.ca) ).

The Strait of Georgia Ichthyoplankton Survey, 1979-1981.
Ichthyoplankton surveys were conducted in the Strait of Georgia (British Columbia) during 1979-1981 to ascertain the onset of fish spawning, and to explore distributional pattern and estimate total biomass of fish species. Oblique tows were made using 0.25m2 Bongos equipped with 351 micron Nitex nets of modified SCOR design. All sampling gear was black to minimize potential avoidance and resulting catch bias. The tow procedure generally followed that established by CALCOFI. This dataset contains a compilation of corrected catches of juvenile fishes, fish eggs and fish larvae by station.

This collection is a legacy product that is no longer maintained. It may not meet current government standards. The correction matrices for the National Topographic Data Base (NTDB), also known under the acronym CORMAT, are products derived from the planimetric enhancement of NTDB data sets at the 1:50 000 scale. The correction matrix enables users to enhance the geometric accuracy of the less accurate NTDB. The matrix is a set of points arrayed on a regular 100-m grid. Each point describes the planimetric correction (DX, DY) to be applied at this location. The position of the points is given in UTM (Universal Transverse Mercator projection) coordinates based on the North American Datum of 1983 (NAD83) . Each file constitutes a rectangular area covering the entire corresponding NTDB data set. Its delimitation corresponds more or less to National Topographic System (NTS) divisions at the 1:50 000 scale. All NTDB data sets at the 1:50 000 scale whose original accuracy was less than 30 m can thus be geometrically corrected. A CORMAT data set contains a list of coordinates and the corresponding corrections to be applied in the form X Y DX DY.

Surficial Geology of the Central Kluane Ranges (parts of NTS 115B/15, 16 and 115G /1, 2, 3, 6 and 7)
Surficial geological mapping in the central Kluane Ranges was undertaken to better understand the distribution and character of surficial materials. Upland surficial materials in the area are dominated by near-source bedrock derivatives. Valley bottom settings, including Shakwak trench and Duke River valley, are characterized by broad open valleys with thick deposits of Quaternary sediment. Permafrost is discontinuous in the study area and its character is affected by slope and aspect, topography and material texture. Mass wasting processes in the study area include rockfall and avalanches, debris flows, debris avalanches and active layer detachment slides. The distribution and character of surficial materials are significant for soil geochemical sampling programs, mineral exploration, infrastructure and development.
N2K 2018 (vector), Europe, 6-yearly, Jul. 2021
This metadata refers to CLMS N2K 2018 product, the Copernicus Land Cover/Land Use (LC/LU) status map, with 2018 as reference year for the classification, tailored to the needs of biodiversity monitoring in selected Natura2000 sites: 4790 sites of natural and semi-natural grassland formations listed in Annex I of the Habitats Directive, including a 2 km buffer zone surrounding the sites and covering an area of 631.820 km² across Europe (EU27, the United Kingdom and Switzerland). The product includes three Emerald sites in Switzerland. LC/LU has been extracted from VHR satellite data and other available data. The production of N2K updates was coordinated by the European Environment Agency (EEA) in the frame of the EU Copernicus programme.
The Copernicus component is governed by Regulation (EU) No 2021/696 of the European Parliament and of the Council of 28 April 2021 establishing the Union Space Programme and the European Union Agency for the Space Programme and repealing Regulations (EU) No 912/2010, (EU) No 1285/2013 and (EU) No 377/2014 and Decision No 541/2014/EU. Within the Copernicus component, a portfolio of land monitoring activities has been delegated by the European Union to the European Environment Agency (EEA) and the DG Joint Research Centre of the European Commission. The Copernicus land monitoring products and services are made available on a principle of full, open and free access, as established by the Commission Delegated Regulation (EU) No 1159/2013 of 12 July 2013. Free, full and open access to the products and services of the Copernicus Land Monitoring Service is made on the conditions that: 1. When distributing or communicating Copernicus Land Monitoring Service products and services (data, software scripts, web services, user and methodological documentation and similar) to the public, users shall inform the public of the source of these products and services. 2. Where the Copernicus Land Monitoring Service products and services have been adapted or modified by the user, the user shall clearly state this. 3. Users shall make sure not to convey the impression to the public that the user's activities are officially endorsed by the European Union.
Generation of a Land Cover/Land Use (LC/LU) dataset by visual image interpretation and delineation based on Very High Resolution (VHR) satellite data from 2018 ±1 year. Additional in-situ and ancillary datasets relevant for the production were also integrated into the workflow to support the LC/LU analysis. The classification provides 55 distinct thematic classes. The class definitions follow a pre-defined nomenclature based on the Mapping and Assessment of Ecosystems and their Services (MAES) typology of ecosystems (at level 1) and are further harmonised with Corine Land Cover and adapted to the specific characteristics of grasslands habitats (levels 2 to 4). The Minimum Mapping Unit (MMU) is 0.5 ha and the Minimum Mapping Width (MMW) is 10 m. The positional accuracy is less than 5 m (according to geo-location accuracy of satellite imagery delivered by ESA: less than 5m RMSE). Producer’s accuracy assessment approach: stratified random point sampling. Interpretation of sampling points was performed on the best available reference data. The overall accuracy is higher than 85%.
Base Hydrography Update is the Alberta Environment and Protected Areas base hydrography dataset, it is an updated of the Base Features Hydrography in Southern Alberta from orthophoto and various sources of provincial base data.
