Where is the Census Bureau statement on the Tiger Line shapefile?
The Census Bureau requests that any repackaging of the TIGER/Line Shapefile data, documentation, and other files accompanying it for distribution include a conspicuously placed statement to this effect on the product’s cover, the first page of the website, or elsewhere of comparable visibility.
How is the Tiger shapefile used for geocoding?
Part 3 of 3 in the TIGER/Line Shapefile Try This! series is not interactive, but instead illustrates how the address ranges encoded in TIGER/Line Shapefiles can be used to pinpoint (more or less!) the geographic locations of street addresses in the U.S.
How is MAF / TIGER an example of geocoding?
MAF/TIGER enables the Bureau to associate census data, which it collects by household address, with the right census areas and voting districts. This is an example of a process called address-matching or geocoding. The MAF/TIGER database embodies the vector approach to spatial representation.
What are the topological rules of the Tiger file?
Topology. By definition, features in the TIGER/Line files conform to a set of topological rules (Galdi 2005): Every edge must be bounded by two nodes (start and end nodes). Every edge has a left and right face. Every face has a closed boundary consisting of an alternating sequence of nodes and edges.
What are tiger and line geodatabases used for?
TIGER/Line Geodatabases TIGER Geodatabases are spatial extracts from the Census Bureau’s MAF/TIGER database for use with geographic information systems (GIS) software. The geodatabases contain national coverage (for geographic boundaries or features) or state coverage (boundaries within state).
Where does the Tiger / Line shapefiles come from?
The TIGER/Line Shapefiles are the fully supported, core geographic product from the U.S. Census Bureau. They are extracts of selected geographic and cartographic information from the U.S. Census Bureau’s Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) database.
