title: Geoserver - GetFeatureInfo of raster/wms layer multiple points/location or bounding box
body: <p>I am using <code>Geoserver 2.8.1</code> version. I have <code>netcdf and grib</code> files, and I am uploading those to <code>Geoserver</code> through <code>Geoserver extensions</code>. After that, I use those data to show layer feature info in the map. (According to zoom scale and image size)I put arrows in the map to reference <code>wind and wave</code> directions. I calculate, to which angle the arrow will be positioned, by getting netcdf info like this; </p>

  <p>I make above request for each point changing only bbox(Lets say 1000 times average). It is killing my application. Is there any way that I can get feature info/values for all the cells/points <strong>in one request</strong>?</p>
  
  <p>I know I can't do it with <code>WMS - getFeatureInfo</code> now, but I am open to any suggestion, only limitation is I need to use java.</p>
  
  <p>Note: I am not looking for values of one point in multiple layers, I am looking for values of multiple points. I can already get values for multiple layers.</p>
