Two Source Types

RoadScope integrates both static and real-time data sources. Understanding the difference is important for accurate route planning.

Static Sources

Static sources are downloaded periodically and cached locally:

• **Cache duration:** 7 days (stored in IndexedDB)
• **Examples:** NBI, SolTecCAN, SolTecDE, SolTecFR, SolTecDOT
• **Use for:** Planning-phase bridge analysis, constraint screening, permit documentation
• **Currency note:** Data reflects the last update from the source agency. Always verify critical constraints with field survey.

Real-Time Sources

Real-time sources are fetched live and cached briefly in memory:

• **Cache duration:** 10 minutes (memory only — cleared on page refresh)
• **Examples:** SolTecON (Ontario 511), SolTecNL (NDW Netherlands)
• **Use for:** Current construction zones, temporary closures, active events
• **Currency note:** Reflects conditions at time of last fetch. Re-load the page or wait for cache expiry to get the latest.

Forcing a Refresh

To force a refresh of static cached data, go to **Settings > Data Sources** and click **Refresh Cache** for the desired source. This forces a fresh download from the source agency.

Data Currency Indicators

RoadScope displays a data currency timestamp for each active source in the map legend. Check this before relying on any source for live operational decisions.
