    USGS developed The National Map (TNM) Gazetteer as the Federal and national standard (ANSI INCITS 446-2008) for geographic nomenclature based on the Geographic Names Information System (GNIS). The National Map Gazetteer contains information about physical and cultural geographic features, geographic areas, and locational entities that are generally recognizable and locatable by name (have achieved some landmark status) and are of interest to any level of government or to the public for any purpose that would lead to the representation of the feature in printed or electronic maps and/or geographic information systems. The dataset includes features of all types in the United States, its associated areas, and Antarctica, current and historical, but not including roads and highways. The dataset holds the federally recognized name of each feature and defines the feature location by state, county, USGS topographic map, and geographic coordinates. Other attributes include names or spellings other than the official name, feature classification, and historical and descriptive information. The dataset assigns a unique, permanent feature identifier, the Feature ID, as a standard Federal key for accessing, integrating, or reconciling feature data from multiple data sets. This dataset is a flat model, establishing no relationships between features, such as hierarchical, spatial, jurisdictional, organizational, administrative, or in any other manner. As an integral part of The National Map, the Gazetteer collects data from a broad program of partnerships with federal, state, and local government agencies and other authorized contributors. The Gazetteer provides data to all levels of government and to the public, as well as to numerous applications through a web query site, web map, feature and XML services, file download services, and customized files upon request. The National Map viewer allows free downloads of public domain geographic names data by state in a pipe-delimited text format. For additional information on the GNIS, go to http://nationalmap.gov/gnis.html.

    The USGS Governmental Unit Boundaries service from The National Map (TNM) represents major civil areas for the Nation, including States or Territories, counties (or equivalents), Federal and Native American areas, congressional districts, minor civil divisions, incorporated places (such as cities and towns), and unincorporated places. Boundaries data are useful for understanding the extent of jurisdictional or administrative areas for a wide range of applications, including mapping or managing resources, and responding to natural disasters. Boundaries data also include extents of forest, grassland, park, wilderness, wildlife, and other reserve areas useful for recreational activities, such as hiking and backpacking. Boundaries data are acquired from a variety of government sources. The data represents the source data with minimal editing or review by USGS. Please refer to the feature-level metadata for information on the data source. The National Map boundaries data is commonly combined with other data themes, such as elevation, hydrography, structures, and transportation, to produce general reference base maps. The National Map viewer allows free downloads of public domain boundaries data in either Esri File Geodatabase or Shapefile formats. For additional information on the boundaries data model, go to http://nationalmap.gov/boundaries.html.

    Archive des polygones d’étendues des inondations au Canada tel que cartographié par Ressources naturelles Canada à partir d’imagerie satellitaire pour la gestion des urgences. En réponse aux événements d’inondations, les services de géomatique d’urgence de Ressources naturelles Canada sont parfois activés par les protocoles de gestion des urgences du Canada. Cet item contient l’archive des produits de cartographies des inondations générés par les services de géomatiques d’urgence de RNCan. Les produits d’inondation générés sont validés au meilleur des informations accessibles. Plusieurs facteurs peuvent affecter la qualité des produits. Ces facteurs inclus, mais ne sont pas limités à: type de capteur, résolution de l’image, couverture nuageuse ou les limites à la méthode d’extraction des polygones d’inondations. Dans cette couche d’information, lorsque possible, la sémiologie des polygones d’inondations est fonction du type d’usage des sols cartographiées, lorsque l’information est indisponible, aucune classe spécifique n’est attribuée et l’étendue brute est représentée. Filtrez par date et zone d’intérêt (AOI) pour visualiser un produit spécifique. Propriétés temporelles accessibles avec le champ "Date UTC". Les fichiers d’archive électronique « .zip » contenant le shapefile, une carte PDF et un fichier « .kmz » de chacun des produits sont accessibles par l’intermédiaire de liens vers le serveur FTP du SGU inscrit dans le champ « URL du packet ». Avis de non-responsabilité Les autorités d’intervention d’urgence sont les principaux utilisateurs des produits cartographiques de l’étendue des inondations en eaux libres, générées à partir de données satellitaires. Ces produits sont créés pour rendre compte de la situation, permettre de l’analyser et faciliter le processus décisionnel pour les interventions d’urgence lors d’inondations importantes. Les produits sont générés rapidement, ce qui laisse peu de temps pour leur édition et leur validation. Ils montrent l’étendue des inondations à la date et à l’heure de l’acquisition des images. Bien que tout soit fait pour en garantir la qualité, ces produits en temps quasi réel peuvent contenir des erreurs. Il est à noter que les algorithmes actuels ne permettent pas de cartographier les zones inondées sous couvert forestier et qu’ils ne sont pas optimisés pour cartographier des inondations en milieu urbain.

    The General Bathymetric Chart of the Oceans (GEBCO) consists of an international group of experts who work on the development of a range of bathymetric data sets and products. GEBCO operates under the joint auspices of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) of UNESCO. See our web site for more information about GEBCO at http://www.gebco.net/. The layer included in this WMS are based on the GEBCO_2014 Grid. The data set was originally published in 2014, last updated in April 2015. Please note the data set has now been superseded by a later version. Further information about GEBCO's products can be found on GEBCO's web site: www.gebco.net. The bathymetric portion of the GEBCO_2014 Grid was largely generated from a database of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. However, in areas where they improve on the existing GEBCO Grid, data sets generated by other methods have been included. Further information about the data sets included in the grid can be found in the documentation that accompanies the data set and is available from https://www.gebco.net/data_and_products/historical_data_sets/#gebco_2014. Within the GEBCO_2014 Grid, the area south of 60S is based on the International Bathymetric Chart of the Southern Ocean (IBCSO) v1 www.ibcso.org. The imagery for land areas in this WMS, north of 60 degrees south, is largely taken from the NASA Blue Marble: Next Generation data set, produced by Reto Stockli, NASA Earth Observatory, the NASA Goddard Space Flight Center (http://earthobservatory.nasa.gov/Features/BlueMarble). For land areas south of 60 degrees south, coastline and ice shelf information is taken from the Scientific Committee on Antarctic Research (SCAR) Antarctic Digital Database coastline dataset (www.add.scar.org/Information). Details on how to download the GEBCO Grid can be found at https://www.gebco.net/data_and_products/gridded_bathymetry_data/. This WMS delivers imagery in a polar view centred on the South Pole. Separate WMS's provided global imagery for the GEBCO Grid and imagery centred on the North Pole. Please note that the GEBCO Grid is mainly a deeper water data set and does not contain detailed bathymetry in shallower water areas. This WMS has been developed by the British Oceanographic Data Centre (BODC) on behalf of the GEBCO community. If imagery from this WMS is included in web sites, reports and digital and printed imagery then we request that the source of the dataset is acknowledged and be of the form 'Imagery reproduced from the GEBCO Grid, version xxxxxx, www.gebco.net'. Where 'version xxxxxx' is the appropriate version number of the GEBCO Grid, given in the layer information below. Also included in this WMS is a layer based on the GEBCO_08, Grid gebco_08_grid_south_polar_view.

  • The 'Land Cover for Agricultural Regions of Canada, circa 2000' is a thematic land cover classification representative of Circa 2000 conditions for agricultural regions of Canada. Land cover is derived from Landsat5-TM and/or 7-ETM+ multi-spectral imagery by inputting imagery and ground reference training data into a Decision-Tree or Supervised image classification process. Object segmentation, pixel filtering, and/or post editing is applied as part of the image classification. Mapping is corrected to the GeoBase Data Alignment Layer. National Road Network (1:50,000) features and other select existing land cover products are integrated into the product. UTM Zone mosaics are generated from individual 30 meter resolution classified scenes. A spatial index is available indicating the Landsat imagery scenes and dates input in the classification. This product is published and compiled by Agriculture and Agri-Food Canada (AAFC), but also integrates products mapped by other provincial and federal agencies; with appropriate legend adaptations. This release includes UTM Zones 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, and 22 for corresponding agricultural regions in Newfoundland, Prince Edward Island, Nova Scotia, New Brunswick, Québec, Ontario, Manitoba, Saskatchewan, Alberta and British Columbia covering approximately 370,000,000 hectares of mapped area. Mapped classes include: Water, Exposed, Built-up, Shrubland, Wetland, Grassland, Annual Crops, Perennial Crops and Pasture, Coniferous, Deciduous and Mixed forests. However, emphasis is placed on accurately delineating agricultural classes, including: annual crops (cropland and specialty crops like vineyards and orchards), perennial crops (including pastures and forages), and grasslands.

    In 2017, the Earth Observation Team of the Science and Technology Branch (STB) at Agriculture and Agri-Food Canada (AAFC) repeated the process of generating annual crop inventory digital maps using satellite imagery to for all of Canada, in support of a national crop inventory. A Decision Tree (DT) based methodology was applied using optical (Landsat-8, Sentinel-2, Gaofen-1) and radar (RADARSAT-2) based satellite images, and having a final spatial resolution of 30m. In conjunction with satellite acquisitions, ground-truth information was provided by: provincial crop insurance companies in Alberta, Saskatchewan, Manitoba, and Quebec; point observations from the BC Ministry of Agriculture, and the Ontario Ministry of Agriculture, Food and Rural Affairs; and data collection supported by our regional AAFC Research and Development Centres in St. John's, Kentville, Charlottetown, Fredericton, Guelph, and Summerland.

    This product provides population counts for 2001 and 2016 for 105 census subdivisions (CSDs) for which the forest sector is a major source of employment income—defined by Natural Resources Canada as 20% or more of total CSD income excluding government transfers. These files were produced by Statistics Canada, Environment, Energy and Transportation Statistics Division, 2018, special tabulation from the 2001 and 2016 Census of Population; Natural Resources Canada, Canadian Forest Services, Economic Analysis Division; Canada’s National Forest Inventory (NFI), 2016, Grouped kNN Map layers, http://tree.pfc.forestry.ca (accessed April 7, 2017). Data from the 2016 Census of Population were used to identify the 105 census subdivisions. Note that changes occur to the number and the boundaries of CSDs between censuses. Adjustments were made to CSD boundaries to account for changes. Some data were suppressed for data quality reasons or to meet the confidentiality requirements of the Statistics Act. Income data were available for 3,675 of 5,162 CSDs. This analysis may therefore underreport the total number of communities for which the forest sector is a major economic driver. Note that a decline in the percentage of forest sector income may be due to a decrease in forest sector income or an increase in income from other sources. The reference period for income data in the Census of Population is the calendar year prior to the census. The forest sector includes North American Industry Classification codes 113 – forestry and logging, 1153 – support activities for forestry and logging, 321 – wood product manufacturing and 322 – paper product manufacturing. These files will also be accessible as web services on the Government of Canada web site Open Maps. (http://open.canada.ca/en/open-maps)
