What are Geographic References?
Geographic information contains either an explicit geographic reference, such as the New Jersey state plane coordinate or latitude and longitude, or an implicit reference such as an address, postal code, census tract name, or road name. An automated process called geocoding is used to create explicit geographic references (multiple locations) from implicit references (descriptions such as addresses). These geographic references allow you to locate features, such as a business and events, such as a hurricane, on the earth’s surface for analysis.
