1 Put information on the Map by geocoding.

2 Specifically, assume that you'd like to use the geocoding information that accompanies Twitter search results to also display a map of the geographical area from which each post originated.

3 The latter part of this process is called geocoding (see Resources).

4 The Twitter Search API allows geocoding information to restrict its results.

5 At this point, you've seamlessly integrated geocoding into your application just as Google Maps does.

6 For our purposes here, geocoding is defined as finding the latitude and longitude for a given address.

7 The first piece of the puzzle is geocoding your data.

8 With these techniques and the geocoding modules and mapping tools,[] you have myriad options for creating region shaded and city-plotted maps.

9 Given that geocoding is a much more complex functionality than simply constructing a linestring, the performance impact is much more noticeable.

10 Despite all the complexities of geocoding, services are available that translate addresses to location.

11 The geocoding service that Google offers is a simple URL that takes a location and other parameters and returns the coordinates for the requested location.

12 For example, let's say that you are working on an application that needs geocoding support, and you've never worked with a geocoding library before.

13 A quick Web search on free geocoder yields a number of potential candidates for the trip planner's geocoding needs.

14 There's a location field that is free form, user defined, and optional geocoding data.

15 The tools and techniques described will allow you to use open source software and freely available geocoding services to create your own customized plots of geographical data.

16 Recall from " Grails services and Google Maps" that you created a Geocoding service to convert street addresses to latitude/longitude points so that an Airport could be plotted on a map.

17 Google does, however, offer its own service to map between logical names and coordinates, which is known as geocoding.

18 The next step is to refactor the Airport infrastructure to take advantage of this new geocoding service.

19 Some of the commonly used location abilities include mapping, geocoding, positioning and routing.
