title: Calculate 100 meter distance when the latitude and longitude is a known point
body: <p>I want to know if it is possible to calculate a 100 meter distance around a given point with a known latitude and longitude. I have some coordinates in a MySQL database and want to know if a specific coordinate lies in 100 meter range from a given point. </p>
  
  <p>I am using the Android platform. I know only one coordinate (Longitude and Latitude) where I am standing (current location) and I want to set the distance range (say 100 meters). </p>
  
  <p>I have more coordinates saved in the database and want to calculate if the other points saved in the database are in 100 meter range from my current location or not. I don't know if I can use GIS database in my application. </p>
