Using TIGER/Line data with CV XE GIS


TIGER/Line shapefiles are extracts from the Census Bureau MAF/TIGER database, containing features such as roads, railroads, rivers, as well as legal and statistical geographic areas. TIGER refers to Topologically Integrated Geographic Encoding and Referencing. TIGER/Line shapefiles do not include demographic data.



Each shapefile contains a .prj file that contains the GIS industry standard well-known text (WKT) format to describe the coordinate system/projection/datum information for each shapefile. Census Bureau shapefiles are in Global Coordinate System North American Datum of 1983 (GCS NAD83). Each .prj file contains the following:




Detailed versus Generalized

Detailed: exact boundaries, all vertices, larger file sizes

Generalized: smoothed boundaries and do not represent the exact boundaries
