“geo” directory/folder (2011)

• Concordance
• MS excel file
• spatial relationship between census tracts (CTs) for current census and

corresponding CTs for the previous census (2006)

• (documentation calls it “Census Tract Conversion File”)

10

“geo” directory/folder (2011)

• Correspondence
• unique identifiers for current census geographic area and the

corresponding unique identifier for previous census geographic area

• Dissemination Areas (DAs)
• Dissemination Areas and Land Area
• Dissemination Blocks
• relationship flag indicates the degree of correspondence between the

geographic areas, for comparison between census years

11

“geo” directory/folder (2011)

• data products
• GAF (precursor to GeoSuite & GeoRef)
• .txt and .xlsx files
• data on which other two are/were built
• GeoSuite

12

“geo” directory/folder (2011)

• Preview
• thoroughly describes all geography and products
• Boundary files
• Correspondence (conversion)
• GeoSuite (GAF)
• Road Network
• PCCF
• Reference maps

13

“geo” directory/folder (2011)

• Ref_products
• reference guides to products
• working papers
• figures (Maps) for CMAs
• Reference maps
• Thematic Maps
• Age & Sex
• Canada (wide)
• CMAs / CSDs
• CMAs / CTs
• Statistical Area Classification (SAC)
• CSDs influenced by CMAs / CAs

14

“geo” directory/folder (2011)

• Spatial information
• ArcInfo (ESRI ArcGIS)
• Cartographic Boundary files (cbf)
• Digital Boundary files (dbf)

15

• for geography DanielB reviewed earlier

“geo” directory/folder (2011)

• Spatial information (con’t)
• ArcInfo (ESRI ArcGIS)
• (cbf)
• (dbf)
• Road Network files
• GIS viewers
• FreeView
• Jump
• TatukGIS
• Guide (Boundary files reference guide)
• MapInfo (another GIS)
• ZipReader

16

some other “GIS / Geo-Spatial” file formats

• ESRI geodatabase
• open with ArcGIS; export as shapefiles
• shapefile(s)
• .shp — feature geometry itself
• .shx — positional index of the feature geometry to allow seeking

forwards and backwards

• .dbf — attribute format; column attributes in dBase (IV) format

also sometimes…

• .prj — coordinate and projection information
• (.sbn .sbx .shp.xml etc)
• e00 (older ESRI Arc Interchange format)
• ArcGIS can convert to shape
• KML/KMZ
• ArcGIS can convert to shape
