La conversion de formats de données est une tâche courante et souvent essentielle dans le traitement de l'information géographique. Si le GeoJSON est largement plébiscité pour sa simplicité et son interopérabilité dans les applications web et les API, le NDJSON (Newline Delimited JSON) offre une approche différente, particulièrement avantageuse pour la gestion de très grands ensembles de données. Chaque ligne étant un objet JSON valide et indépendant, le NDJSON facilite le traitement en flux, l'ingestion progressive dans les bases de données NoSQL ou l'analyse distribuée, sans nécessiter de charger l'intégralité du fichier en mémoire. Cette page vous guide à travers le processus de transformation de vos fichiers GeoJSON en NDJSON, une opération qui optimise la performance et la flexibilité pour vos projets cartographiques et analytiques, qu'il s'agisse de géomarketing, d'urbanisme ou de recherche scientifique.
- Analyse de données cadastrales massives au Québec
- Intégration de flux de données géospatiales pour la planification urbaine en Suisse
- Traitement distribué de relevés topographiques pour grands projets d'infrastructure en France
Dans les administrations publiques et les organismes de recherche de ces régions, l'adoption croissante de solutions de 'big data' rend la conversion vers le NDJSON particulièrement pertinente pour l'exploitation de jeux de données géographiques volumineux, souvent issus de capteurs ou de bases de données nationales.
