Census departments are often the starting point for both census data and geographic information systems supporting data. Census geocoder efforts can provide data and programmatic access to users interested in matching addresses to geographic locations and entities containing map coordinates.
Goals and Objectives
Governments and data users need resources for locating census geography, address information, and location details. Census counts people and associates them with addresses. Geocoding services provide tools to look up addresses to convert them to latitude/longitude and other GIS info that can be used by other applications.
Hardware: GIS systems that are capable of both reading and recording GPS information
Software: GIS-encoded databases (such as Tiger in the United States), mapping software, and GIS-enabled apps
Services: Geocoding services, systems integration, and system maintenance
Use Case Summary
Besides ongoing census efforts conducted by many governments, that information is tied to geographic databases that automate the mapping and related geographic activities required to support multiple types of survey programs. More layers of data and visualization are being added to such systems.
