To Convert the TIGER to an Arc/Info Coverage

• Run ARC
• use the command: TIGERARC Lakexll.F5 new_cover_name to import the line features.
• use the command: BUILD cover_name LINES to build line topology for the coverage.
• Run ArcView and ADD the coverage to the View.
• From the Project Window, ADD the TABLE named "cover_name.ACODE" to the project (Note: it is an INFO file).
• Find the corresponding TIGER_Line_ID fields in the two tables and Link the "ACODE" file with the attribute file.
• Use the Query Tools in ArcView to select all Streets in Lakewood.

Use the CFCC (Census Feature Classification Code) and FIPS_Place_Left and Right fields to select ROADS (code "A") that are a part of the City of Lakewood (Place number 39892).
• Use the THEME/Convert_to_Shapefile option to save the selected records into an ArcView Shapefile format.
• Make a Basemap using the Lakewood Streets shapefile.
