title: Country code from a latitude longitude position (without using geocoding services)
body: <p>How can i get the country code from a latitude longitude position?</p>
  
  <p>I know that there are many geocoding services available, but they don't meed my requirement because my application gets blocked a few hours after it goes live (many geocoding requests).</p>
  
  <p>Most geocoding services also offer commercial services, but they are not yet a option because the project is in it starting blocks.</p>
  
  <p>I did a bit of research and think i found a way to do it:
  Get a shape file (or other data file) that contains the borders of all countries (in polygons).
  Next just look in which polygon the lat/lng position is.
  Finally read the meta data from the specific polygon.</p>
  
  <p>Does anyone know where i can get a shape file (or other format) that includes polygons (or just lines) that show the borders of all countries in the world?</p>
  
  <p>Or is there maybe a easier way to solve this problem?</p>
