title: Easiest way to edit a huge geoJSON?
body: <p>I'm sitting here with a huge geoJSON that I got from an Open Street Map shape-file. However, most of the polygons are unnecessary. These could, in theory, easily be singled out based on certain properties.</p>
  
  <p>But how do I query the geoJSON file to remove certain elements (features)? Or would it be easier to save the shape-file in another format (working in QGIS)? </p>
