    The following table identifies and briefly describes the selected attributes comprising the content of the 2014 Road Network File.

    Table 4.1 2014 Road network file record layout

    Attribute domain values

    Representation of unknown or no value

    The null value is used to represent values of the street's name, type, direction and address range that are either missing or non-existent.

    The null value is also used for geographic unique identifier, name and type to indicate that it is outside of Canada.

    Street type

    Indicates the street type associated with the arc.

    Table 4.2 Street type

    Street direction

    Street direction can be used in conjunction with street name and type to identify common street elements (e.g., Elm ST S versus Elm ST W or Elm ST). Street direction has no relation to the direction the street arc was digitized.

    Software formats

    The 2014 Road Network File is available for download from the Statistics Canada website in the following formats:

    • ArcGIS®
      File extension: .shp
    • Geography Markup Language (GML) 3.1.1
      File extension: .gml
    • MapInfo®
      File extension: .tab

    This reference guide does not provide details on specific software packages that are available for use with the 2014 Road Network File. Users are advised to contact the appropriate software vendor for information.

    File extension and accented character information

    The ArcGIS®, Geography Markup Language and MapInfo® files are compressed into WinZip® files (file extension .zip).

    A XML schema file (.xsd) is included to describe and validate the structure and content of the .gml files.

    The 2014 Road Network File contains attributes with accented characters. They were successfully tested on desktop versions of ArcGIS® 9.3.1 and MapInfo® 11.0.1.

    Geographic representation

    The 2014 Road Network File is available on the Statistics Canada website in the following geographic representation:

    Projection: Lambert conformal conic
    False easting: 6200000.000000
    False northing: 3000000.000000
    Central meridian: -91.866667
    Standard parallel 1: 49.000000
    Standard parallel 2: 77.000000
    Latitude of origin: 63.390675
    Linear unit: metre (1.000000)

    Datum: North American 1983 (NAD83)
    Prime meridian: Greenwich
    Angular unit: degree
    Spheroid: GRS 1980

    The North American Datum of 1983 (NAD83) is an adjustment of the 1927 datum that reflects the higher accuracy of geodetic surveying.

    Users of the Road Network File can transform the file into the representation that best satisfies their needs knowing the effects these representations have on angles, areas, distances and direction. Users have the option to choose the best projection in concert with the maps objectives.

    File naming convention

    Spatial product file names follow a file naming convention. The file projection, geographic level, geographic coverage, file type, geographic reference date, file format and language are embedded within the file name. Standardizing the names of the files facilitates the storage of compressed files, all having the extension .zip.

    Each file name is 13 characters in length. All alphabetic characters are in lower case to maintain consistency.

    First character: projection of file

    1. l - projection of file is Lambert conformal conic

    Next three characters: primary geographic level of file/type of file

    1. rnf - road network file

    Next three numbers: geographic code of coverage

    1. 000 - Canada

    Next character: file type

    1. r - road network file

    Next two numbers: geographic reference date

    The geographic reference date is a date determined by Statistics Canada to finalize the geographic framework for which statistical data are collected, tabulated and reported. The reference date for the 2014 Road Network File is January 1, 2014.

    1. 14 - geographic reference date is 2014

    Next character: file format
