GeoJSON and Shapefile are OpenStreetMap road lines, like an OSM extract, for one year and one area.
Road lines (OSM)
Choose a year and a province. The file holds a LineString per way, not city-centre points.
Choose a province to download the lines.
API
Responses use JSON and include stored data with its sources. Outside this site, the API needs an API key; downloads stay free. Credit the source and its licence.

GET /api/roads?kelompok=utama&area=32&tahun=2026Road length per city/regency and year since 2015 for each road group, with each area's land size. kelompok: semua, utama, lokal, tanah, setapak. area: a province or city/regency code. tahun: one counted year. Without parameters, every group, area and year. Roads mapped in OpenStreetMap on 1 January, not roads built that year.
GET /api/export/jalan?format=shp&kelompok=utama&area=32.73&tahun=2026OpenStreetMap road lines (LineString) for one year and one province or city/regency. format: geojson or shp. area is required. tahun: 1 January of that year; without tahun, the latest counted year. Not city-centre points.
Methodology
Data coverage
Road lines and their type from OpenStreetMap's copy of Indonesia on 1 January of each year since 2015.
Processing
- Road types are grouped: main roads (toll, trunk, primary, secondary), local and village roads (tertiary, village links, residential, access roads), dirt tracks, and footpaths. Sidewalks, cycleways and steps are not counted.
- All vehicle roads are main roads, local and village roads, and dirt tracks. Footpaths are counted separately.
- Each stretch of road is measured on the earth's surface and counted in the village where its midpoint lies. A road crossing a boundary is split close to it. City and regency figures are the sum of their villages.
- Road per km² is road length divided by the area's land area according to BIG.
- A year whose copy we have not counted yet is shown as no data, not zero.
- GeoJSON and shapefile downloads are the OpenStreetMap lines themselves (one LineString per stretch) for one year and one province or city/regency, not city-centre points.
- The live map draws those lines, not a colour per city. From far away only main roads; zoom in for city and village roads.
Limitations
- These are roads that have been mapped, not all roads that exist. A road enters OpenStreetMap when someone draws it, not when it is built.
- Indonesia's total rose from about 240,000 km in 2015 to 1.27 million km in 2020, mostly because existing roads were mapped. Since 2021 it has grown by under 5% a year, so recent change is more likely new road, but can still be mapping.
- Change per city or regency can be negative. It is a difference in mapped length, not a count of demolished roads: a road may be retagged, deleted from the map, or its midpoint may move into another area.
- Every road type comes from the highway tag mappers set in OpenStreetMap, not from government or Google data. Main roads are motorway, trunk, primary and secondary; local and village roads are tertiary, unclassified, residential and service; dirt tracks are track; footpaths are path.
- That type follows how mappers see the road being used, not the official national, provincial, regency/city or village status set by the government. That official status is not available as an open map.
- Road condition, such as paved or damaged, is not counted.
