“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) -for geography DanielB reviewed earlier 15

“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 17
