ArcView GIS Quick Tips Geocoding To geocode addresses, you need a reference theme (street theme) to serve as a base map. The reference theme is usually a street theme with attributes that specify the street name, street type, and a range of addresses that occur along each street. In this case we will be using the roads_42 file as a reference theme. You also need and address table (.dbf) that contains the addresses you want to locate as points on the map. The geocoding process consists of three steps: 1. Preparing the reference theme for geocoding (this is called making the reference theme matchable ). 2. Batch matching the addresses. During this step, ArcView compares the table of addresses to the street information in the reference theme and looks for matches. Each matched address is added as a point in a new geocoded theme. 3. Rematching the addresses that couldn’t be batch matched. ArcView also adds these points to the geocoded theme. The step first in geocoding is to make the reference theme matchable by selecting an address style. An address style determines which address components (e.g. street name, street type, direction, zip code) will be required in the address-matching process. The

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
