About GeoJSON Sequence (GeoJSONSeq)

Newline-delimited GeoJSON features — streamable and appendable, good for pipelines.

Worth knowing: One feature per line; not all viewers understand it.

About CSV (with coordinates) (CSV)

Plain-table points: columns for X/Y (or easting/northing, lon/lat) become geometry.

Worth knowing: Point data only on read (X/Y columns); geometry of other types is written as WKT.

We read it locally with GDAL compiled to WebAssembly — nothing is uploaded.
