***Note from Migration:***
Original Title was: Use geojson-geom/wkt/prepared-geometry as geometry filter for for geospatial database connectors
One could generate a custom geojson really easy now days. for example by visiting geojson.io you can draw your own polygon. Of course this is just an example as there are numerous similar other sites that can generate similar outputs.
I would be nice if i could use this geojson as well instead of only having the option of a Search Envelope.
