    The Grain Elevators in Canada dataset maps the list of grain elevators in Canada as provided by the Canadian Grain Commission (CGC). The elevators have been located as much as possible to an actual location rather than generalizing to the station name centroid. Additionally car spot information from CN, CP and the grain companies has been added where this has been published. This dataset attempts to provide a temporal and geographical extent of the grain elevators in Canada.

    As part of a scientific assessment of critical habitat for boreal woodland caribou (Environment Canada 2011, see full reference in accompanying documentation), Environment Canada's Landscape Science and Technology Division was tasked with providing detailed anthropogenic disturbance mapping, across known caribou ranges, as of 2015. This data comprises a 5-year update to the mapping of 2008-2010 disturbances, and allows researchers to better understand the attributes that have a known effect on caribou population persistence. For this 2015 update an additional, separate higher-resolution database was created by repeating the process using 15-metre panchromatic imagery. For the 30-metre database only, the line and poly data were buffered by a 500-metre radius, representing their extended zone of impact upon boreal caribou herds. Additionally, forest fire polygons were merged into the anthropogenic footprint in order to create an overall disturbance footprint. These buffered datasets were used in the calculation of range disturbance levels and for integrated risk assessment analysis. / Dans le cadre d'une évaluation scientifique de l'habitat essentiel du caribou des bois boréal (Environnement Canada, 2011, voir la référence complète dans la documentation compagnement), la division de la science et de la technologie du paysage d'Environnement Canada avait pour tâche de fournir une cartographie détaillée des perturbations anthropiques, à partir de 2015, à travers les aires de répartition connues du caribou. Ces données comprennent une mise à jour quinquennale de la cartographie des perturbations de 2008-2010 et permettent aux chercheurs de mieux comprendre les attributs qui ont un effet connu sur la persistance de la population de caribou. Pour cette mise à jour de 2015, une base de données distincte, à résolution supérieure, a été créée en répétant le processus à l'aide d'images panchromatiques de 15 mètres. Pour la base de données de 30 mètres seulement, les données de ligne et les données poly ont été mises en mémoire tampon dans un rayon de 500 mètres, représentant leur zone d'impact étendue sur les troupeaux de caribou boréal. De plus, les polygones d'incendies de forêt ont été fusionnés dans l'empreinte anthropique afin de créer une empreinte de perturbation globale. Ces jeux de données tamponnés ont été utilisés dans le calcul des niveaux de perturbation des aires et dans l'analyse intégrée d'évaluation des risques.

    Målingerne til de preussiske målebordsblade blev foretaget 1877-78, herefter foretoges flere revisioner. Målingerne var egentlig beregnet som grundkort for det militære operationskort i 1:100.000, og især højedemålingerne har lidt under dette. Der var ingen forskrifter om nøjagtigheden; men jernbaneakser og afgrænsninger til vand prioriteredes højt. Projektionen er speciel; den "Preussische Polyederprojektion" - gradudsnittet på kortet bliver afbildet som et trapez, hvor netsnitpunkterne rører jordoverfladen. Kortbladsnummereringen går fra vest mod øst, startende i nord. Når der er lakuner i nummereringen, skyldes det Østpreussen med Memel (Klaipeda), som også var preussisk på dette tidspunkt.

    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.
