Newline-delimited GeoJSON (also known as "line-oriented GeoJSON", "GeoJSONL", "GeoJSONSeq" or "GeoJSON Text Sequences") is a text-based geospatial file format that is particularly convenient for transformation and processing. Each line can be read independently, parsed, and processed, without the entire file ever having to be parsed in memory, which is great for huge files.
It is simply newline-oriented JSON applied to GeoJSON, and formalised as RFC 8142.
FeatureCollection.Feature minified, on its own line, separated by \n.Features.
