Geocoding

What in the world is Geocoding? The basic idea is to supply your address and find the matching latitude and longitude values like this free geocoding service. Maps within Google use this technique as well as other web maps. It is kind of scary how much information is available from your physical address or publically listed phone number if you also retrieve the census track number. While there is free US Census TIGER data, the alternative is expensive up-to-date Tele Atlas data.
