Geographic Attribute File (GAF), 2006 Census Coordinate system: 4269 - "NAD83" Abstract: The Geographic Attribute File is a dataset that contains census geographic information at the Dissemination Block level for all of Canada for the 2006 census. Dissemination Blocks are the smallest geographic area for which population and dwelling count data are disseminated. Each record includes geographic coordinates, population and dwelling counts, land area, names, unique identifiers, and geographic codes for linkages with other census boundaries. The original dataset is available from Statistics Canada as a text file (.txt) or an Excel spreadsheet (.xlsx). For viewing in Scholars GeoPortal, the dataset was converted from its original tabular format into a Shapefile format using the point coordinates available for each record. These coordinates are only for Dissemination Areas, not Dissemination Blocks, so in some cases, there are several points at the same location (where a Dissemination Area is composed of several Dissemination Blocks). The original data tables, and other supporting files and documentation, are available as additional downloads from Scholars GeoPortal.

  Scope Level: dataset

  The geographic area boundaries, names, codes, and the relationships among the various geographic levels are found on Statistics Canada’s Spatial Data Infrastructure. These data for administrative areas are updated using information from provincial and territorial sources. These data for statistical areas are updated using the results of the previous census and input from users.

  
  

  Process step:

  The files were converted from an Excel Spreadsheet (.xlsx) into an ESRI Shapefile (.shp) for view and download on Scholars GeoPortal.

  Statistics Canada: The Spatial Data Infrastructure (SDI) is the source for all 2006 Digital Boundary File products. Primary data manipulation of the product layers included preserving the geographic hierarchy of attributes inherent within a geography. This data manipulation included copying source data to a production environment and the joining of hierarchical geographic attributes. The final data treatment was an output of various file formats supported by Geographic Information System (GIS) software.
