Given a binary numpy array (array of 0s and 1s where 0=background), what would be the best way to polygonise this raster and write it to a geojson?

https://rasterio.readthedocs.io/en/latest/cli.html#shapes is a command line program for extracting GeoJSON shapes from a raster. It's a thin wrapper around rasterio.features.dataset_features() (see https://github.com/mapbox/rasterio/blob/master/rasterio/rio/shapes.py).
