TIGERweb allows the viewing of TIGER spatial data online and for TIGER data to be streamed to your mapping application. TIGERweb consists of a web mapping service and a REST service.

      Thew web mapping service is an Open Geospatial Consortium (OGC) service that allows users to visualize our TIGER
      (Topologically Integrated Geographic Encoding and Referencing database) data. This service consists of two
      applications and eight services. 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 applications are a
      simple way to view our TIGER data without having to download the data. The web Mapping services provide a simple HTTP
      interface for requesting geo-registered map images from our geospatial database. It allows users to
      produce maps containing TIGERweb layers with layers from other servers. TIGERweb consists of
      the following two applications and eight  services: 
      Applications: TIGERweb,  TIGERweb Decennial
      Services: Current,  ACS16, ACS15, ACS14, ACS13, Econ12, Census 2010 (for the TIGERweb application), Physical Features (for the TIGERweb application),
      Census 2010 (for the TIGERweb Decennial application), Census 2000 and Physical Features (for the TIGERweb Decennial application)

      The REST service is a way for Web clients to communicate with geographic information system (GIS) servers through Representational
      State Transfer (REST) technology. It allows users to interface with the REST server with structured URLs using a computer language like PYTHON or JAVA. The
      server responds with map images, text-based geographic information, or other resources that satisfy the request. There are three groups of services: 
      TIGERweb, TIGERweb Generalized and TIGERweb Decennial. TIGERweb consists of boundaries as of January 1, 2016 while TIGERweb Decennial consists of boundaries
      as they were of January 1, 2010. TIGERweb Generalized is specifically designed for small-scale thematic mapping.

     The following REST services are offered for both groups:
