The National Rail Network (NRWN) is a geometric and attributive description of the Canadian rail network. The NRWN product consists of the features classes: Track Segment, Railway Crossing, Railway Station, Marker Post, Junction and Railway Structure. Descriptive attributes include amongst others: Track Classification, Track Name, Track Operator, Track User, Track Owner, Subdivision Name, Junction Type, Crossing Type, Level of Crossing, Warning System, Transport Canada Identifier, Station Name, Station Type, Station User, Structure Type.

This dataset contains flight track data from the High Altitude Ice Crystals - High Ice Water Content (HAIC-HIWC) project that took place in Cayenne, French Guiana. The data is from the NRC Convair 580, operated by the National Research Council Canada, for the 12 flights flown during the project and are in kml format.

The Canadian Geographical Names Data Base (CGNDB) is the authoritative national database of Canada's geographical names. The purpose of the CGNDB is to store place names and their attributes that have been approved by the Geographical Names Board of Canada (GNBC), the national coordinating body responsible for standards and policies on place names. The CGNDB is maintained by Natural Resources Canada, through the Canada Centre for Mapping and Earth Observation. The geographic extent of the CGNDB is the Canadian landmass and water bodies; the temporal extent is from 1897 to present. This dataset is extracted from the CGNDB on a weekly basis, and consists of current officially approved names, feature type, coordinates of the feature, decision date, source, and other attributes. The output file formats for this product are: text (CSV), Shape (SHP), and Keyhole Markup Language (KML). Content advisory: The Canadian Geographical Names Database contains historical terminology that is considered racist, offensive and derogatory. Geographical naming authorities are in the process of addressing many offensive place names, but the work is still ongoing. For more information, please contact the GNBC Secretariat.

GeoMet provides access to the Environment Canada's Meteorological Service of Canada (MSC) raw numerical weather prediction (NWP) model data layers and the weather radar mosaic via two Open Geospatial Consortium web service standards: Web Map Service (WMS) and Keyhole Markup Language (KML). Meteorological layers are dynamically served through the Web Map Service (WMS) standard to enable end-users to display meteorological data within their own tools and on interactive web maps, and served through KML standard.Meteorological Service of Environment Canada forecasts, analysis and observations layers. This is not an operational 24/7 service. Documentation: http://www.ec.gc.ca/meteo-weather/default.asp?lang=En&n=C0D9B3D8-1

This data provides the integrated cadastral framework for Canada Lands. The cadastral framework consists of active and superseded cadastral parcel, roads, easements, administrative areas, active lines, points and annotations. The cadastral lines form the boundaries of the parcels. COGO attributes are associated to the lines and depict the adjusted framework of the cadastral fabric. The cadastral annotations consist of lot numbers, block numbers, township numbers, etc. The cadastral framework is compiled from Canada Lands Survey Records (CLSR), registration plans (RS) and location sketches (LS) archived in the Canada Lands Survey Records.

There are two types of boundary files: cartographic and digital. Cartographic boundary files portray the geographic areas using only the major land mass of Canada and its coastal islands. Digital boundary files portray the full extent of the geographic areas, including the coastal water area.

Topographic maps produced by Natural Resources Canada conform to the National Topographic System (NTS) of Canada. Indexes are available in three standard scales: 1:1,000,000, 1:250,000 and 1:50,000. The area covered by a given mapsheet is determined by its latitude and longitude. 1:1,000,000 mapsheets are identified by a combination of three numbers (e.g. 098). 1:250,000 mapsheets are identified by a combination of numbers, and letters ranging from A through P (e.g. 098C). Sixteen smaller segments (1 to 16) form blocks used for 1:50,000 mapping (e.g. 098C03).

The Aboriginal Lands of Canada Legislative Boundaries web service includes legislative boundaries of Indian Reserves, Land Claim Settlement Lands (lands created under Comprehensive Land Claims Process that do not or will not have Indian Reserve status under the Indian Act) and Indian Lands. More specifically it includes the following lands: 1) Indian Reserves that include: 1.1) surrendered lands or a reserve, as defined in the Indian Act (this definition excludes Indian Settlements and Indian Communities); and 1.2) Sechelt lands, as defined in the Sechelt Indian Band Self-Government Act, chapter 27 of the Statutes of Canada, 1986; 2) Land Claim Settlement Lands that include: 2.1) Category IA land or Category IA-N land, as defined in the Cree-Naskapi (of Quebec) Act, chapter 18 of the Statutes of Canada, 1984 (category 1B and category II Lands are excluded from this definition); 2.2) Settlement land, as defined in the Yukon First Nations Self-Government Act, and lands in which an interest is transferred or recognized under section 21 of that Act (only Yukon First Nations Settlement Lands, which were surveyed and the survey plan recorded, are included in the map service); 2.3) Inuit Owned Lands as defined in the Agreement between the Inuit of the Nunavut Settlement Area and Her Majesty the Queen in Right of Canada given effect and declared valid by the Nunavut Land Claims Agreement Act (it includes all parcels that have been surveyed and those that do not require a survey (this includes the islands)); 2.4) Gwich’in Lands as defined in the Gwich’in Comprehensive Land Claim Agreement, given effect and declared valid by the Gwich’in Land Claim Settlement Act; 2.5) Inuvialuit Lands as defined in the Western Arctic (Inuvialuit) Claims Settlement Act; 2.6) Sahtu Lands as defined in The Sahtu Dene and Métis Comprehensive Land Claim Agreement given effect and declared valid by the Sahtu Dene and Métis Land Claim Settlement Act; and 2.7) Tlicho lands, as defined in the Tlicho Agreement, given effect and declared valid by the Tlicho Land Claims and Self-Government Act; 3) Indian Lands that include: 3.1) Lands in the Kanesatake Mohawk interim land base, as defined in the Kanesatake Mohawk Interim Land Base Governance Act, other than the lands known as Doncaster Reserve No. 17. The data available for download is the former Geobase-Aboriginal Lands product. There are some attribute differences between the data available for download and the web service; however both contain the same underlying data. Please refer to the Supporting Documents for additional information on the Geobase - Aboriginal Lands dataset. Work is under way to align these two data products.

Many geometrical schemes - or map projections - are used to represent the curved surface of the Earth on map sheets. Canada uses the Universal Transverse Mercator (UTM) system. It is called transverse because the strips run north-south rather than east-west along the equator. This data class shows a 1 km x 1 km UTM NAD83 grid that is a standard reference index for Ontario. It includes: * Military Grid Reference * Fire Base Map identifier * Fire Base Map Block * Atlas identifier
