Geocode With Google

Google founders Larry Page and Sergey Brin announce new features for Google Maps.


Geocoding is the process of converting an address into latitude and longitude coordinates. Geocoding provides a specific point on the surface of the earth that can't be confused with any other place so it is more precise than a postal address. If you have a global positioning satellite receiver that needs coordinates in latitude and longitude or if you want to engage in the hobby of geocaching where objects are hidden at specific GPS coordinates, you can Geocode an address using Google Maps.


Instructions


1. Browse to Maps.Google.com on your computer.


2. Type in the address that you want to geocode into the search bar and then press "Enter." Note that if you don't have a specific address, you can use the navigation tools to zoom into the location on the map for which you want the latitude and longitude.


3. Right-click on the map at the point where you want the coordinates. Click "What's Here?" The geocoding is done and the results are displayed in the search bar. The numbers are displayed with the latitude first. Positive numbers are north of the equator and negative numbers are south. The longitude is next with negative numbers being west of the prime meridian and positive numbers being to the east. So, for example, the geocode for the Portland International Airport is: "45.588816,-122.594032."
