How to convert an address to a latitude longitude

Question

How would I go about converting an address or city to a latitude longitude  Are there commercial outfits I can  rent  this service from  This would be used in a commercial desktop application on a Windows PC with fulltime internet access

User · Answer

When you convert an address or object to a lat/long it is called Geocoding.

There are a lot geocoding solutions around. The solution right for your project will depend on the acceptability of the licensing terms of each geocoding solution. Both Microsoft Virtual Earth and Google Maps offer solutions which are free to use under a very restrictive licenses...

you can use bing maps soap services  where you can reference reverse geocode service to find lat long from address here is the link http   msdn microsoft com en-us library cc980922 aspx

You want a geocoding application  These are available either online or as an application backend    Online applications    Google has a geocoding API  Backend applications    GeoStan

Google has a geocoding API which seems to work pretty well for most of the locations that they have Google Maps data for   http   googlemapsapi blogspot com 2006 06 geocoding-at-last html  They provide online geocoding  via JavaScript    http   code google com apis maps documentation services html Geocoding  Or backend geocoding  via an HTTP request    http   code google com apis maps documentation services html Geocoding Direct  The data is usually the same used by Google Maps itself   note that there are some exceptions to this  such as the UK or Israel  where the data is from a different source and of slightly reduced quality

You could also try the OpenStreetMap NameFinder  or the current Nominatim   which contains open source  wiki-like street data for  potentially  the entire world

User · Answer

Nothing much new to add  but I have had a lot of real-world experience in GIS and geocoding from a previous job  Here is what I remember   If it is a  every once in a while  need in your application  I would definitely recommend the Google or Yahoo Geocoding APIs  but be careful to read their licensing terms   I know that the Google Maps API in general is easy to license for even commercial web pages  but can t be used in a pay-to-access situation  In other words you can use it to advertise or provide a service that drives ad revenue  but you can t charge people to acess your site or even put it behind a password system   Despite these restrictions  they are both excellent choices because they frequently update their street databases  Most of the free backend tools and libraries use Census and TIGER road data that is updated infrequently  so you are less likely to successfully geocode addresses in rapidly growing areas or new subdivisions   Most of the services also restrict the number of geocoding queries you can make per day  so it s OK to look up addresses of  say  new customers who get added to your database  but if you run a batch job that feeds thousands of addresses from your database into the geocoder  you re going to get shutoff   I don t think this one has been mentioned yet  but ESRI has ArcWeb web services that include geocoding  although they aren t very cheap  Last time I used them it cost around 1 5cents per lookup  but you had to prepay a certain amount to get started  Again the major advantage is that the road data they use is kept up to date in a timely manner and you can use the data in commercial situations that Google doesn t allow  The ArcWeb service will also serve up high-resolution satellite and aerial photos a la Google Maps  again priced per request   If you want to roll your own or have access to much more accurate data  you can purchase subscriptions to GIS data from companies like TeleAtlas  but that ain t cheap  You can buy only a state or county worth of data if your needs are extremely local  There are several tiers of data - GIS features only  GIS plus detailed streets  all that plus geocode data  all of that plus traffic flow direction speed limits for routing  Of course  the price goes up as you go up the tiers   Finally  the Wikipedia article on Geocoding has some good information on the algorithms and techniques  Even if you aren t doing it in your own code  it s useful to know what kind of errors and accuracy you can expect from various kinds of data sources
