VI. TIGER/LINE CENSUS FILES, 1990 CODES Source Codes A series of codes that specify the original digital source of the line segment, such as a Census Bureau's 1980 GBF/DIME-File or a USGS 1:100,000- scale DLG-3 file. Value Description (Blank) Nondocumented A 1980 GBF/DIME-File B USGS 1:100,000-Scale DLG-3 File C Other USGS Map D Census Bureau Precensus Update E Census Bureau Enumerator Update F Census BureauOther Operations G Unconfirmed Local Official Updates Direction Codes (Blank) No Direction N North, Norte S South, Sur E East, Este W West, Oeste NE Northeast, Norte Este, Nordeste NW Northwest, Norte Oeste, Noroeste SE Southeast, Sur Este, Sudeste SW Southwest, Sur Oeste, Sudoeste EX Extended, Extension Diacritical Codes The following three special characters will appear in the name field for the TIGER/Line file only for Puerto Rico: ] Preceding Character has acute accent [ Preceding Character has dieresis # Preceding Character has tilde Census Feature Class Codes (CFCC) This is a series of codes that provides more detailed information on the classification of the line segment, such as class of road, class of stream, and so forth. This field provides more information than the 1980 GBF/DIME- File "NS" code (nonstreet feature code) field. For line segments that originated with the USGS DLG-3 files, the CFCC is based on the USGS classification code in the DLG-3 file. For line segments that originated with the 1980 GBF/DIME-Files, the CFCC is based on the NS code and other feature identification content of the GBF/DIME-File. A list of these codes follows.

The interstate highways that were identified by name as such in the GBF/DIME-File, are classified as Class 1 roads. Also, in the GBF/DIME-File coverage areas, users may not find many roads with alternate names; if an alternate name is provided, it usually represents another local name and not a Route Number.

For example, a property line will appear in the file only when a statistical or political boundary is known to follow that property line, and only then will a line carry the F40 property line code. FEATURE TYPE ABBREVIATIONS For all hydrography and for all nonroad features, the feature type normally will follow the feature name in the feature name field. If the feature type is not one of the types that appears in the following list, the feature type will appear in the feature name field. Roads normally will have an entry in the feature type field. The feature type is present only when it is part of the proper name. One should not confuse proper name feature types with the census feature class codes (CFCC). The following entries may appear in the feature type field. These name abbreviations also may appear in the feature name field.
