This product contains restored 1971 census enumeration area boundaries for Canada's largest cities. It provides the public with a historical spatial data set to be used for reference, mapping, spatial and time series analysis. The restored boundaries include population and dwelling statistics.

Description

The Environmental Assessment (EA) projects layer includes all projects for which an environmental assessment under the Canadian Environmental Assessment Act, 2012 is ongoing. The location of a project included in the dataset is approximate based on information provided by proponents. More than one location may be identified for a given project. This dataset does not include information related to the project footprint. Additional information on EA projects included in this dataset is available on the Project Home Page and in the project description documents on the Canadian Environmental Assessment Registry Internet site.

Flood extent polygons representing current year floods throughout Canada as monitored by Natural Resources Canada using satellite imagery for emergency response. In response to large flood events, Natural Resources Canada, for the provision of emergency geomatics services (NRCan), 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 flood products generated in the past year. For any data relating to previous years, please refer to the Floods in Canada – Archive entry. The flood products are generated and validated on a best effort basis. Various factors may affect the quality of the flood polygons. Those factors include but are not limited to: sensor type, image resolution, cloud coverage or limits to the flood polygon extraction method. In this layer, a symbology is applied to the flood polygons based on the underlying land use classification, when available, or is simply unclassified and shows the gross flood extent otherwise. Filter on date and Area of Interest (AOI) to view specific products. Time-enabled on Date UTC field. ".zip" file packages that contain the shapefile, PDF map, and ".kmz" of individual product items are available through the FTP links listed in the Package URL field. 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.

On a délimité les concentrations de plumes de mer, de petites et grandes gorgones, et d'éponges sur la côte est du Canada par le biais de l'analyse spatiale des données sur les prises accessoires recueillies lors des relevés effectués par navire de recherche. L'analyse a adopté une approche de l'Organisation des pêches de l'Atlantique Nord-Ouest (OPANO) dans la zone de réglementation du Bonnet Flamand et le sud-est des Grands Bancs. On a eu recours à une analyse du noyau de densité a fin de délimiter les hautes concentrations. De telles analyses ont été réalisées pour chacune des cinq zones biogéographiques de l'est du Canada. Les plus grandes colonies de plumes de mer ont été découvertes dans le chenal Laurentien qui coupe le golfe du Saint-Laurent, alors que les grands regroupements de gorgones ont été trouvés dans l'Arctique de l'Est et le nord de la pente continentale du Labrador. De grosses éponges en boule de plusieurs espèces de Geodia se trouvaient le long des pentes continentales au nord des Grands Bancs, tandis qu'on a identifié sur le Plateau néo-écossais une seule population de grosses éponges en forme de tonneau de l'espèce Vazella pourtalesi. On fournit la latitude et la longitude marquant les positions de tous les traits qui forment ces colonies et d'autres concentrations denses, ainsi que les positions de tous les traits de chalut qui ont permis de remonter à la surface du corail noir, un taxon que l'on ne retrouve pas enregroupement, qui est d’une grande longévité et vulnérable à la pression de la pêche.
