GeoJSON-Seq 형식 소개

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.

GeoJSON-Seq 지도 사용자

🏗

스트림 처리

The file is read line by line, so memory does not depend on the size of the export.

💻

빅데이터 파이프라인

A ready input for Spark, Kafka and tippecanoe, where data comes as a stream of records.

📊

로깅

Records are appended to the end and move on down the line as they arrive.

🎨

jq/ndjson 처리

Every line is a self-contained JSON, so the usual command line utilities work with no adaptation.

🗺

ETL 워크플로

Splitting, filtering and loading in batches are done with standard tools, without intermediate conversions.

다운로드

완성된 GeoJSON-Seq 파일을 다운로드하여 jq에서 여세요

내보낸 뒤 여는 방법

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.
