The TIGERweb and TIGERweb Decennial web-based applications allow the users to visualize our TIGER(Topologically Integrated Geographic Encoding and Referencing database) data. The applications allow users to select features and view their attributes, to search for features by name or geocode, and to identify features by selecting them from a map. The TIGERweb and TIGERweb Decennial applications provide a simple way to view our TIGER data without having to download the data.
The TIGERweb and TIGERweb Decennial applications offer the ability to view:
Because geographic and locational context and relationships are important, the TIGERweb application determines which geographic entities and features may be visible based on map scale.
Users have the capability to turn on and off linear features and geographic entities by type. This allows users to limit the amount of data on the map by selecting only the features and entity types they would like to see.
The TIGERweb application contains the latest version of the geographic extent of legally defined geographic areas as reported, generally reflecting the boundaries of governmental units in effect as of January 1, 2013, or legal and statistical area boundaries that have been adjusted and/or corrected since the 2010 Census.
This vintage enables users to see the most current boundaries of governmental units that match the data from the surveys that use 2013 geography, such as the American Community Survey (ACS 2013).
In addition to the January 1, 2013 vintage (ACS 2013), the TIGERweb application also contains data as of January 1, 2012 (ACS 2012) and data as of January 1, 2010 (2010 Census).
TIGERweb Decennial now contains both 2010 Census geography (data as of January 1, 2010) and Census 2000 (data as of January 1, 2000) geography that has been adjusted and/or corrected since Census 2000.
