The maps in the Toronto Census Atlas Online were created by combining boundary files (spatial data) with census data in a mapping program called ArcView. Statistics Canada was the source for both the boundary files and the census data. ArcView is a product of ESRI Corporation and is available on a public access PC in the Map Library, 5th floor, Robarts Library. Some usage restrictions apply.
Section 1. Importing Census Files into ArcView
ArcView uses a seperate program called Import to translate data from an ArcInfo export file into an ArcView readable format. On the public access PC in the Map Library, this program is available under the ArcView menu icon.
The path for the data available on the public access PC can be accessed here.
Use the Import Program (in Windows) to convert an ArcInfo export file containing census digital boundary files to a ArcView usable coverage source file destination file (filename.e00) (anyname) ie. c:\data\arc\gca535ct.e00 c:\public\temp\tor91 Open ArcView (in Windows) Open the boundary file in ArcView Window "Untitled" New Button - activates window "View1" View - Add Theme -select theme Theme - Table - activates "Attributes of..." table window Open the data file in ArcView Project - Add Table - select datafile to add - datafile.dbf window activated Editing the datafile.dbf Table - Start Editing Edit - Add Field for the new ct_name field Give new field a name ie. "Ctcode" (this name does not have to be the same name as in the boundary file) Field type: String Width: 7 Make the field current - highlight its label by clicking on it Field - Calculate [Geography].Left(7) If the datafile has a record for the summation of all its CTs, do this: Click on the record to be deleted - it will highlight in yellow (to de-select: Edit - Select_None) Edit - Delete_Records Note: When you are finished editing, make sure you go to Table - Stop Edits - Save Edits, or else Join will not work. Prepare the datafile for linkage Make the datafile.dbf window active Click on the field label which will join to the boundary file Sort datafile records in ascending order (use button) Prepare the boundary file for linkage Now, make the boundary file window active Click on the field label to which the datafile will be joined Sort boundary file records in ascending order (use button) Joining the datafile to the boundary file Make sure that the boundary file is the destination file - it is active Table - Join - the datafile should disappear Scroll along the boundary file to see if the datafile data fields are present Mapping the datafile data Activate window "View1" Theme - Edit Legend - activates the legend editor Legend type: Graduated colour Classification Field: select the feature to map There are many things here to customize Press Apply button
