TIGERweb Overview
TIGERweb is a web-based system that allows users to visualize our TIGER (Topologically Integrated Geographic Encoding and Referencing database) data in several ways:
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 provide a simple way to view our TIGER data without Geographic Information System (GIS) software and without downloading data. The applications use our TIGERweb REST Services.
The TIGERweb WMS and TIGERweb REST Services allow users to integrate our data into their own GIS or custom web-based applications.
