Ons data en sy lisensies
SA Roads is uit twee lae data gebou, met twee verskillende lisensies. Hulle word meganies apart gehou — elke veld in ons databasis teken aan waar dit vandaan kom — en hierdie bladsy sê wat elkeen is, aan wie dit behoort, en hoe om ‘n kopie te kry.
1. Die padnetwerk — OpenStreetMap, ODbL 1.0
Die paaie self — waar hulle loop, hul nommers en name, of hulle teer of gruis is — is afgelei van OpenStreetMap.
© OpenStreetMap-bydraers. Die padlaag is beskikbaar onder die Open Database-lisensie 1.0.
Omdat ons daarop bou, is ons padlaag ‘n Afgeleide Databasis onder daardie lisensie, en ons is jou dieselfde vryheid verskuldig wat OpenStreetMap ons gegee het: die data terug, onder dieselfde voorwaardes.
Laai dit af
osm-derived.geojson.gz — gezipte GeoJSON, ongeveer 1,6 MB.
Dit bevat een kenmerk per padstrek: die meetkunde, die padnommer, die naam, die teer-gruis-verdeling, die lengte, en die OpenStreetMap-way-id’s waaruit elke strek gebou is. Elke waarde daarin is van OSM afgelei. Dit word herbou wanneer ons weer uit OpenStreetMap intrek, nie volgens ‘n tydskedule nie — die laag verander net wanneer die intrek dit verander.
Wat doelbewus NIE in daardie lêer is nie
Geen gemeenskapsbydrae verskyn in die ODbL-uitvoer nie. Nie ‘n verslag nie, nie ‘n gradering nie, nie ‘n bevestiging nie, nie kommentaar nie, en niks wat ‘n bydraer identifiseer nie. Dit is ‘n lisensiebesluit, nie ‘n privaatheidsbesluit nie: bydraers publiseer onder CC BY 4.0 (afdeling 2), en om hul werk in ‘n ODbL-Afgeleide Databasis in te vou sou dit herlisensieer sonder hul instemming. Twee onafhanklike kontroles dwing dit af — die uitvoer word gebou uit ‘n momentopname wat elke gemeenskapskryf voorafgaan, én elke waarde word ongeag daarvan op sy eie aangetekende bron gefiltreer. As ‘n enkele nie-OSM-waarde die uitset bereik, weier die uitvoer om die lêer hoegenaamd te skryf.
2. Wat bestuurders rapporteer — CC BY 4.0
Alles wat ‘n persoon bydra — padtoestande, sinkplaat- en slaggatverslae, gevare, voertuiggeskiktheid, graderings, bevestigings, fasiliteite en kommentaar — word deur die outeur gepubliseer onder Creative Commons Erkenning 4.0.
Jy mag dit hergebruik, ook kommersieel, solank jy die bron erken.
Hierdie laag is nie deel van die ODbL-uitvoer hierbo nie, en die twee word nooit gemeng nie.
3. Hoe die twee apart gehou word
Elke veld op elke pad dra sy eie herkoms: of die waarde van OpenStreetMap kom, van ‘n outomatiese verrykingsloop, van die gemeenskap, of van ‘n administrateur — saam met die OpenStreetMap-way-id’s daaragter.
Dit is wat die skeiding meganies maak eerder as ‘n saak van sorgvuldigheid. Dit is ook waarom ‘n waarde wat uit OpenStreetMap gesaai is, in die program as ongeverifieer gemerk word en niks tel in die gemeenskapskonsensus nie: dit is ‘n vertrekpunt, nie ‘n verslag van ‘n bestuurder nie.
4. Wat SA Roads nie is nie
SA Roads is ‘n onafhanklike gemeenskapsprogram. Dit verteenwoordig nie ‘n regeringsinstansie nie, en is nie verbonde aan of onderskryf deur SANRAL, die Nasionale Departement van Vervoer, of enige provinsiale of munisipale padowerheid nie.
SA Roads publiseer wat bestuurders rapporteer oor ‘n pad. Dit is nie advies nie, en dit is nie ‘n amptelike verklaring dat ‘n pad oop, toe of veilig is nie — daardie funksies behoort aan SANRAL en die provinsiale padowerhede. Elke bewering in die program word met sy ouderdom gewys. Besluit self, en gaan die amptelike bronne na voordat jy ry:
- SANRAL — South African National Roads Agency
- SANRAL i-Traffic — lewendige verkeer, voorvalle en padwerke
- Nasionale Departement van Vervoer
- Provinsiale regerings en hul padowerhede
5. Kontak
Vrae oor die data, die lisensies of die uitvoer: privacy@saroads.co.za.
As jy iets verkeerd sien met die padnetwerk self — ‘n pad wat nie bestaan nie, ‘n verkeerde naam, ‘n verkeerde nommer — is die duursame oplossing om dit in OpenStreetMap reg te stel. Dit vloei by die volgende intrek na ons terug, en na almal anders wat daarop bou.

Our data and its licences
SA Roads is built from two layers of data with two different licences. They are kept mechanically separate — every field in our database records where it came from — and this page says what each one is, who it belongs to, and how to get a copy.
1. The road network — OpenStreetMap, ODbL 1.0
The roads themselves — where they run, their numbers and names, whether they are tar or gravel — are derived from OpenStreetMap.
© OpenStreetMap contributors. The road layer is available under the Open Database Licence 1.0.
Because we build on it, our road layer is a Derivative Database under that licence, and we owe you the same freedom OpenStreetMap gave us: the data back, under the same terms.
Download it
osm-derived.geojson.gz — gzipped GeoJSON, roughly 1.6 MB.
It contains one feature per road stretch: the geometry, the road number, the name, the surface split, the length, and the OpenStreetMap way ids each stretch was built from. Every value in it is OSM-derived. It is regenerated whenever we re-ingest from OpenStreetMap, not on a timer — the layer only changes when the ingest changes it.
What is deliberately NOT in that file
No community contribution appears in the ODbL export. Not a report, not a rating, not a confirmation, not a comment, and nothing identifying a contributor. That is a licence decision, not a privacy one: contributors publish under CC BY 4.0 (section 2), and folding their work into an ODbL Derivative Database would relicense it without their agreement. Two independent checks enforce it — the export is built from a snapshot that predates any community write, and every value is filtered on its own recorded source regardless. If a single non-OSM value reaches the output, the export refuses to write the file at all.
2. What drivers report — CC BY 4.0
Everything a person contributes — road conditions, corrugation and pothole reports, hazards, vehicle suitability, ratings, confirmations, facilities and comments — is published by its author under Creative Commons Attribution 4.0.
You may reuse it, including commercially, as long as you credit the source.
This layer is not part of the ODbL export above, and the two are never mixed.
3. How the two are kept apart
Every field on every road carries its own provenance: whether the value came from OpenStreetMap, from an automated enrichment pass, from the community, or from an administrator — together with the OpenStreetMap way ids behind it.
That is what makes the separation mechanical rather than a matter of care. It is also why a value seeded from OpenStreetMap is badged unverified in the app and counts for nothing in the community consensus: it is a starting point, not a report from a driver.
4. What SA Roads is not
SA Roads is an independent community app. It does not represent a government entity, and it is not affiliated with or endorsed by SANRAL, the National Department of Transport, or any provincial or municipal road authority.
SA Roads publishes what drivers report about a road. It is not advice, and it is not an official statement that a road is open, closed or safe — those are functions of SANRAL and the provincial road authorities. Every claim in the app is shown with its age. Decide for yourself, and check the official sources before you travel:
- SANRAL — South African National Roads Agency
- SANRAL i-Traffic — live traffic, incidents and roadworks
- National Department of Transport
- Provincial governments and their road authorities
5. Get in touch
Questions about the data, the licences or the export: privacy@saroads.co.za.
If you spot something wrong with the road network itself — a road that does not exist, a wrong name, a wrong number — the durable fix is to correct it in OpenStreetMap. It flows back to us at the next ingest, and to everyone else who builds on it.
