title: How to extract map data for iphone app?
body: <p>I have a website with a <a href="http://www.pokerdiy.com/find-poker-games.aspx" rel="nofollow">map and lat/long points for poker games</a>.</p>
  
  <p>I am outsourcing an iphone/android (using Appcelerator I think) app to show this data on a mobile map.</p>
  
  <p>The part I need help on is HOW To expose this data to the client?! It's a DotNetNuke site (C#/SQL)</p>
  
  <p>I think I have to write a webservice that queries the game table on the website and exposes something - but I don't know what format the dataset needs to be in or how to handle the reads (I assume the user goes to a location on the map and it asks for all the games with a distance x from this point - I assume I have to code that into my webservice so I am sending a small dataset?</p>
  
  <p>Any tips appreciated - I don't know much about mapping or iphone clients!</p>
