Building a Store Locator ASP.NET Application Using Google Maps API (Part 2)
Last week’s article, Building a Store Locator ASP.NET Application Using Google Maps API (Part 1) , was the first in a multi-part article series exploring how to add store locator-type functionality to your ASP.NET website using the free Google Maps API . Part 1 started with an examination of the database used to power the store locator, which contains a single table named Stores with columns capturing the store number, its address and its latitude and longitude coordinates. Next, we looked at using Google Maps API’s geocoding service to translate a user-entered address, such as San Diego, CA or 92101 into its latitude and longitude coordinates. Knowing the coordinates of the address entered by the user, we then looked at writing a SQL query to return those stores within (roughly) 15 miles of the user-entered address.
