title: Which are the best geo Coding APIs available for free?
body: <p>I want to use geo coding services in my site which are the APIs available for this, Java based solutions will be preferred and I want to use this in a commercial project so please suggest appropriate options i.e. APIs which can be used in such projects freely..</p>
  
  <p>Before asking this question I have tried searching on net and found that few popular geoCoding APIs are the ones from Google and yahoo. And few answers in SO suggest using Google API (Which seems very popular one), before deciding I want to know is their any other option and what are the available solutions for this ? </p>
  
  <p>Even A Link to some blog/ site which contains detailed analysis of all these sites will be of great help.</p>
