I got an iphone app, that I am searching for the specific places from google maps and the information of those places are coming from the database and it's merged with google maps information. Yet, the problem is I have to grab the information of those places in the given lattitude and longtitude.
How can I query to the database (entityframework, MSSQL), as draw a circle of 1 km in the given lattitude and longtitude and bring the results?
P.S. To sum up, you can think this as google's maps service customization for my own database as I got the longtitude and lattitude.
