# GeoJSONSeq: sequence of GeoJSON features

New in version 2.4.

Driver short name

GeoJSONSeq

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.

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.)

## Datasource

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` (GDAL >= 3.5.2): size in MBytes of the maximum accepted single feature, default value is 200MB. Or 0 to allow for a unlimited size.

## 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 = int_number: Maximum number of figures after decimal separator to write in coordinates. Default to 7. “Smart” truncation will occur to remove trailing zeros.

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

- ID_FIELD=string. 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.
