This process involves comparing input addresses with an established authority file to obtain coordinates. Successful geocoding depends on the characteristics of the input file and the authority file, and the algorithm used in matching the addresses. The algorithm needs to process inexact matches by employing a weighted searching strategy. The weight setting on each address component determines the output quality. No research has examined the relationship between the weight and the output quantitatively, although findings can help GIS users generate better results. In addition, the choice of an authority file has important cost implications. No previous research compares the position precision of the output derived from the two major types of authority files (TIGER-based and zip+4 databases) from the perspective of benefits compared with costs. This research examines these two issues. |
