GeoJSON Sequences (Newline-delimited)
Open BetaGeoJSON-Seq ni toleo la GeoJSON lililotenganishwa kwa mistari ambapo kila mstari ni Kipengele tofauti. Linafaa kwa utiririshaji, ukataji kumbukumbu, na mifumo ya Data Kubwa.

Vipengele Muhimu
Kuhusu Muundo wa GeoJSON-Seq
GeoJSON-Seq (RFC 8142) is the same GeoJSON laid out line by line: one line is one whole feature. There is no common FeatureCollection wrapper, which means you do not have to read the entire file to get to the first feature.
This is a pipeline format. Such files are read line by line and processed as a stream: filtered with jq, fed to tippecanoe to build vector tiles, poured into Kafka or Spark, cut into pieces by line count. Memory usage does not depend on the size of the export.
The output is a single .geojsonl with the features of all the selected layers written one after another. Each has a _layer property with the name of its source layer, OpenStreetMap attributes are preserved, and coordinates are WGS84 (EPSG:4326) with six decimal places.
The format is good at exactly what ordinary GeoJSON is bad at on large volumes, and vice versa: you cannot put a .geojsonl straight into Leaflet — the lines are first assembled into a FeatureCollection or processed as a stream.
Programu Gani Hufungua Faili za GeoJSON-Seq
Programu na programu-tumizi zifuatazo zinaweza kufungua, kuhariri, na kufanya kazi na faili za GeoJSON Sequences (Newline-delimited) (.geojsonl) zilizosafirishwa kutoka OSM2CDR:
Format specifications
- Open standard
- 3D coordinates supported
- Lossless (no quality loss)
- Stores feature attributes
- Output: 1 file
- RFC 8142 GeoJSON Text Sequences (newline-delimited). Streamable line-by-line — ideal for big-data pipelines and incremental loading.
Nani Hutumia Ramani za GeoJSON-Seq
Jinsi ya Kusafirisha GeoJSON-Seq
Jinsi ya Kufungua Baada ya Kuhamisha
- jq — jq -c 'select(.properties._layer=="roads")' map.geojsonl > roads.geojsonl filters out the layer you need without loading the file into memory.
- Tippecanoe — tippecanoe -o map.mbtiles map.geojsonl builds vector tiles: the line-based format is its native input.
- QGIS and ogr2ogr — GDAL reads GeoJSONSeq out of the box: ogr2ogr -f GPKG out.gpkg map.geojsonl.
- Python — read the file line by line and parse json.loads(line): memory does not depend on the volume; to bring the whole layer up, use geopandas.read_file("map.geojsonl").
- Splitting it up — an ordinary split -l 100000 map.geojsonl part_ gives valid pieces: every line is self-contained.

Наконец-то карты можно скачать в векторе. Автору спасибо!
всё очень круто, не ожидал что просто приду и скачаю кусочек карты! спасибо!!!
ОГРОМНОЕ СПАСИБО!!! ОЧЕНЬ ХОРОШАЯ ПРОГРАММА!!! Искал карту в векторе на стыке 3 стран - очень помогло!!
Ты - молодец! Сделал большое и нужное дело!
Иван, спасибо огромное! Не просто человек - Человечище!
иван, вы просто чудо. Спасибо за неимоверно крутой сервис
