OpenStreetMap+
We use OpenStreetMap as a base map and then combine our technology, 3rd party data sources & 100s billions of points of GPS probe data, to create navigation-quality maps of the planet.
OpenStreetMap has a community of 4 million members and each day thousands of volunteers enhance the map by adding new roads, buildings, and parks — everything that matters for cities and towns across the globe.
It's free!
While OpenStreetMap (OSM) offers a free and community-driven approach to mapping, its data quality and structure often fall short of the rigorous standards required for high-quality location-based solutions and navigation. Its lack of hierarchical structure, inconsistent data quality, and missing critical information like geocoding and address points may limit its usability. NDrive's data improvement process addresses these limitations, ensuring reliable and accurate navigation experiences.
NDrive OSM data improvement process
Ingestion
Data download and ingestion, independent of map source or structure, performing data cleanup.
Aggregation
Data aggregation with feature inference: turn and access restrictions, road category, speed profiles, traffic speed, geometry corrections, real-time traffic, incident report, user generated content.
Processing
Data processing and validation, inconsistency verification and automatic topology fixing of polygons and edges (overlaps, self-intersection, unclosed, roundabouts geometry, pseudo-nodes, etc).
Support
Support for third-party traffic sources with OpenLR format.
Fixes
Complement and fix of bad data with several other public and crowdsourced sources for area hierarchies, administrative areas, geocoding, zip-codes, address points, points of interest, etc.
QA
Automatic data quality assurance performed at each stage of the pipeline.
