From 1988 until 2006, these files were in ASCII text and included only geographic data. To render the files, the Census Bureau recommended using a geographic information system (GIS) program or similar software. Releases from 2007 onward were Shapefiles instead of ASCII text. The Census 2000 release is available in both formats. The Shapefiles and relationship files are compressed into ZIP files, with one zipped file per layer. The Shapefile ZIP contains a .cpg character encoding file, a .dbf tabular attribute (database) file, a .prj Coordinate System Information (projection) file, a .shp file containing feature geometry, a .shx file containing an index of the feature geometry, and two XML files that contain metadata. The zipped relationship file contains a .cpg character encoding file, a .dbf tabular attribute (database) file, and two XML files that contain metadata. The Shapefile format is proprietary but fully and openly documented and maintained by ESRI, and it has widespread adoption. The TIGERLine Shapefiles are also openly documented, with documentation maintained by the U.S. Census Bureau. There are a number of software packages and open libraries that can read and write Shapefiles. Therefore, TIGERLine Shapefiles can be retained as-is." ; dcterms:identifier "NF00892" ; rdfs:label "NF00892" ; wikidata:p1195 "cpg" ; wikidata:p1195 "dbf" ; wikidata:p1195 "prj" ; wikidata:p1195 "shp" ; wikidata:p1195 "shx" ; wikidata:p1195 "xml" ; wikidata:p1195 "zip" ; wikidata:p2748 "https://pronom.nationalarchives.gov.uk/fmt/2114" ; wikidata:p3266 "https://www.loc.gov/preservation/digital/formats/fdd/fdd000280.shtml" ; wikidata:p973 "https://en.wikipedia.org/wiki/Topologically_Integrated_Geographic_Encoding_and_Referencing" ; wikidata:p973 "https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html" ; wikidata:p973 "https://www.wikidata.org/wiki/Q2384319" ; wikidata:p973 "https://www2.census.gov/geo/pdfs/maps-data/data/tiger/tgrshp2025/TGRSHP2025_TechDoc.pdf" ; nara:category naraid:Geospatial ; nara:formatName "Topologically Integrated Geographic Encoding and Referencing Files (TIGER/Line) Shapefiles" ; nara:preservationAction naraid:Retain ; nara:preservationPlan "Retain" ; nara:riskLevel naraid:Moderate ; nara:tools "Global Mapper" ; . a owl:Ontology ; .
