The National Topographic Data Base (NTDB) comprises digital vector data sets that cover the entire Canadian landmass. Geomatics Canada has digitized and structured thousands of topographic maps, creating a complete and uniform product that can be highly useful in a broad range of industries. The NTDB includes features such as watercourses, urban areas, railways, roads, vegetation, and relief.

The NRN product is distributed in the form of thirteen provincial or territorial datasets and consists of two linear entities (Road Segment and Ferry Connection Segment) and three punctual entities (Junction, Blocked Passage, Toll Point) with which is associated a series of descriptive attributes such as, among others: First House Number, Last House Number, Street Name Body, Place Name, Functional Road Class, Pavement Status, Number Of Lanes, Structure Type, Route Number, Route Name, Exit Number. The development of the NRN was realized by means of individual meetings and national workshops with interested data providers from the federal, provincial, territorial and municipal governments. In 2005, the NRN edition 2.0 was alternately adopted by members from the Inter-Agency Committee on Geomatics (IACG) and the Canadian Council on Geomatics (CCOG). The NRN content largely conforms to the ISO 14825 from ISO/TC 204.

The National Road Network (NRN), version 1.0 focuses on providing a quality geometric description and a set of basic attributes of Canadian road phenomena. The first release of the NRN product will not include Resource/Recreation roads. Geographic Data Files (GDF) V4 from ISO/TC 204 were used as a guideline for this model. The NRN product strives to comply, to the degree possible, with GDF vocabulary (Class names, attribute names, and definitions). The modeling work of the NRN was primarily based on Linear Reference System (LRS) concepts. This approach allows the management of geometric representation separately from attribute information (referred to as event in LRS). Unique Identifiers are associated with each geometric and event object. These IDs (called National Identifiers - NIDs) will lead to more efficient management of updates between data producers and data users. The Centre for Topographic Information - Sherbrooke (CTIS), part of Natural Resources Canada (NRCan), produced the first version of the NRN. CTIS continues to pursue its goal of capturing and managing NRN data within a network of partners. These partner organizations are selected for their specific interests or for their ease in offering adequate, up-to-date representations of road phenomena. These data must be the product of a homogenous, standardized view of the entire Canadian landmass. The data model can (and must) extend beyond the smallest common denominator obtained with the partners. The model must therefore contain two levels of information: mandatory data and optional data. Data homogeneity will thereby be ensured by a minimum set of data. Beyond the minimum level, the model serves as a target for all partners. Minimum content has been defined for attributive and geometric data. The NRN data will serve as a foundation for several applications. The available output file format for the product are: GML (Geography Markup Language) in ASCII and SHAPE (ESRI - TM).

The National Topographic Data Base (NTDB) comprises digital vector data sets that cover the entire Canadian landmass. Geomatics Canada has digitized and structured thousands of topographic maps, creating a complete and uniform product that can be highly useful in a broad range of industries. The NTDB includes features such as watercourses, urban areas, railways, roads, vegetation, and relief. The organizational unit for the NTDB is the National Topographic System (NTS), based on the North American Datum of 1983 (NAD83). Each file (data set) consists of one NTS unit at either the 1:50,000 or 1:250,000 scale. Furthermore, the data is now available by themes within a file. The ground data is depicted through points, lines, and areas.

NWT Communities - 1:2M-1:8M scale (38)

These are the communities of the Northwest Territories. Some community locations were revised so that they coincided with their respective locations in the NRN Road Layer downloadable from Geobase (http://www.geobase.ca/geobase/en/data/nrn/index.html;jsessionid=0B3DEB504A7ECB0D212A55439F7F7893) - downloaded March 2009 - (ie. points were moved to be in the centre of their communities' road network) POP06 attribute info was taken directly from Stats Canada website March 2009 (http://www12.statcan.ca/census-recensement/2006/dp-pd/prof/92-591/details/Page.cfm?Lang=E&Geo1=PR&Code1=61&Geo2=PR&Code2=01&Data=Count&SearchText=Northwest%20Territories&SearchType=Begins&SearchPR=01&B1=All&GeoLevel=&GeoCode=61)
