Converts a GeoJSON file on disk into a newline-delimited output, following the ndjson specification. So you can combine it with the ndjson-cli tools, for instance.
npm install -g geojson2ndjson
geojson2ndjson myfile.geojson | ...
Or read from standard input:
cat myfile.geojson | geojson2ndjson | ...
Or multiple files:
geojson2ndjson *.geojson > everything.nd.json
Converts a line-delimited GeoJSON file on disk into regular GeoJSON output, with no validation.
npm install -g geojson2ndjson
ndjson2geojson myfile.json | ...
Or read from standard input:
cat myfile.json | ndjson2geojson | ...
List the properties of every feature, without the geometries:
geojson2ndjson myfile.geojson | ndjson-map d.properties
Remove every property except "name" from a GeoJSON file:
geojson2ndjson myfile.geojson | ndjson-map 'd.properties = {name: d.properties.name}, d' | ndjson2geojson > myfile-out.geojson
