Geocoding is an advanced and difficult process and unfortunately is not a perfect science. However, AggData is confident that the system we have developed provides as accurate data as is available. Our primary method of geocoding relies on the same system that Google uses to map the addresses you type in a search bar to find locations. Underneath this service are databases common to most geocoders, including NAVTEQ and Tele Atlas. We do our best to take advantage of the extra data we are able to extract from our primary sources, and we continually find ways to improve and more accurately place that marker directly on the business rooftop.
