GeoJSONSeq: sequence of GeoJSON features

New in version 2.4.

Driver short name


Driver built-in by default

This driver is built-in by default

This driver implements read/creation support for features encoded individually as GeoJSON Feature objects, separated by newline (LF) (Newline Delimited JSON) or record-separator (RS) characters (RFC 8142 standard: GeoJSON Text Sequences)

Such files are equivalent to a GeoJSON FeatureCollection, but are more friendly for incremental parsing.

The driver automatically reprojects geometries to WGS84 longitude, latitude, if the layer is created with another SRS.

Appending to an existing file is supported since GDAL 3.6

Driver capabilities

Supports Create()

This driver supports the GDALDriver::Create() operation

Supports Georeferencing

This driver supports georeferencing

Supports VirtualIO

This driver supports virtual I/O operations (/vsimem/, etc.)


The driver accepts three types of sources of data:

  • Uniform Resource Locator (URL) - a Web address to perform HTTP request

  • Plain text file with GeoJSON data - identified from the file extension .geojsonl or .geojsons

  • Text passed directly as filename, and encoded as GeoJSON sequences

The URL/filename/text might be prefixed with GeoJSONSeq: to avoid any ambiguity with other drivers.

Configuration options

The following configuration option is available:

  • OGR_GEOJSON_MAX_OBJ_SIZE=<MBytes>: (GDAL >= 3.0.2) Defaults to 200. size in MBytes of the maximum accepted single feature, or 0 to allow for a unlimited size (GDAL >= 3.5.2).

Layer creation options

  • RS=[YES/NO]: whether to start records with the RS=0x1E character, so as to be compatible with the RFC 8142 standard. Defaults to NO, unless the filename extension is "geojsons"

  • COORDINATE_PRECISION=<integer>: Defaults to 7. Maximum number of figures after decimal separator to write in coordinates. "Smart" truncation will occur to remove trailing zeros.

  • SIGNIFICANT_FIGURES=<integer>: Defaults to 17. Maximum number of significant figures when writing floating-point numbers. If explicitly specified, and COORDINATE_PRECISION is not, this will also apply to coordinates.

  • ID_FIELD=value: Name of the source field that must be written as the 'id' member of Feature objects.

  • ID_TYPE=[AUTO/String/Integer]: Type of the 'id' member of Feature objects.
