title: Warp using Java GDAL API
body: <p>I am trying to warp a dataset using Java GDAL API.
  However, GDAL Java API is not documented and it is unclear which options <code>WarpOptions</code> take. 
  I feed <code>-tr 15 15</code> just like for <code>gdalwarp</code>. This results in <code>Option not found error</code>:</p>
  
  <pre><code>String gdalSource = "LC81910242015182LGN00_B4.TIF";
  Dataset originalData = gdal.Open(gdalSource, gdalconstConstants.GA_ReadOnly);
  Vector&lt;String&gt; options = new Vector&lt;&gt;();
  options.add("-tr 15 15");
  WarpOptions warpOptions = new WarpOptions(options);
  Dataset[] src_array = {originalData};
  Dataset dataset = gdal.Warp("warp.tif", src_array, warpOptions);
  </code></pre>
  
  <p>What is the option to reduce/increase the resolution?
  Where can I get the list of possible options?</p>
