Street Network Files (SNF), 1991 Census Coordinate system: 4269 - "NAD83" Abstract: This data series contains two Street Network Files (SNF) produced by Statistics Canada for the 1991 census. The dataset only covers urban areas. Street Network Files Skeletal Street Network Files The original data files are from the Data Liberation Initiative (DLI), a Statistics Canada program that provides data to academic institutions in Canada. The original files have been converted from the Arcinfo Interchange E00 file format (.e00) or the MapInfo TAB file format (.tab) into a shapefile format (.shp), as part of a data migration project to enhance the spatial use of the data. The original data files, and other supporting files and documentation, are available as additional downloads from Scholars GeoPortal.

  Process step:

  Scholars Portal: The original data has been converted into ESRI Shapefile (.shp) format. It was projected to NAD83 for consistency between census years and boundary types. And polygons were dissolved to unique identifiers to allow for one-to-one joins with associated tabular data.

  Scholars Portal: This service represents converted data provided by the Data Liberation Initiative (DLI) program at Statistics Canada, and has been altered from its original Arcinfo Interchange E00 file format (.e00) and/or MapInfo TAB file format (.tab).
