Have you ever wanted to know the shortest possible route travelled between multiple locations? So does the U.S. Postal Service, UPS, and thousands of other logistics and shipping companies around the world. In fact, known as the “travelling salesman problem”, it has been a problem under close scrutiny for more than a century. In the latest issue of JSMag, I show you how to incorporate the Google Maps API’s traveling salesman algorithm implementation into your location-based services!
As I sit here this morning penning the latest installment of my ongoing Google Maps series for Developer.com, it’s difficult to believe that the first tutorial in this growing collection was written over five years ago!
Although some of this material is now slightly outdated due to API changes made in the version 3 release, it’s still serves as pretty useful material if you’re looking to ramp up your knowledge in a hurry. To help you get started, I’ve aggregated a list of all 12 articles here.
My latest contribution to JSMag published this month.
This occasional series introducing various facets of the powerful Google Maps API has examined quite a few different features that are likely to appear in an enterprise web-based mapping implementation, ranging from calculating user-defined route distances to using the Google Maps API Geocoder to convert mailing addresses to their respective coordinates. In this installment, I discuss yet another feature that has become standard, particularly on the web sites of large retail chains: the “Store Locator.”
The Store Locator feature provides web site visitors with an easy way to determine the location of nearby stores, typically done by first asking the visitor to provide his or her zip code. The site then consults a database containing all of the chain locations, somehow determining which stores reside in or around the visitor’s zip code. The locator feature is also often enhanced by providing the user with an option to view stores residing within a specified radius of the provided zip code, such as 10 miles, 20 miles, or 100 miles. In this tutorial, I’ll show you one way to create this feature using the Google Maps API, JavaScript, PHP, and a MySQL database.
