Data Discrepancies
You notice that the data displayed in Benchmrk doesn't match what you expect, or data has changed between visits. This is usually related to caching, data update schedules, or the difference between Snapshot data and live data.
Possible Causes
Stale Cached Data
Your browser caches map tiles, search results, and point details to improve performance. Sometimes this cached data becomes outdated.
Symptoms:
- Mark details show old values that you know have been updated
- Search results don't include recently added marks
- Map tiles show outdated imagery or labels
Resolution:
- Hard refresh the page — Press
Ctrl+Shift+R(Windows/Linux) orCmd+Shift+R(Mac) to bypass the cache. - Clear browser cache — Clear cached data for the Benchmrk domain in your browser settings.
- Wait for cache expiry — Cached data expires automatically. Most data refreshes within a few hours.
Jurisdiction Data Update Schedules
Each Jurisdiction updates its survey mark data on its own schedule. Benchmrk reflects the latest data available from each state's survey authority.
| Jurisdiction | Typical Update Frequency |
|---|---|
| NSW | Regular updates from NSW Spatial Services |
| VIC | Periodic updates from Land Use Victoria |
| QLD | Updates from Queensland Globe / Dept. of Resources |
| SA | Updates from SA Government data services |
| TAS | Updates from Land Tasmania |
| NT | Updates from NT Government |
| ACT | Updates from ACT Government |
If data seems outdated: The source authority may not have published an update yet. Benchmrk can only display data that has been provided by the jurisdiction.
Snapshot vs Live Data
Snapshots capture a point-in-time view of a Survey Mark's data. The live data may have changed since the snapshot was taken.
Symptoms:
- Snapshot shows different values than the current point details panel
- Coordinates or metadata differ between snapshot and live view
This is expected behaviour. Snapshots are designed to preserve historical state. To see the current data, view the mark directly on the map rather than through a snapshot.
To compare changes over time: View the snapshot history for a mark to see how its data has evolved across multiple snapshots.
If you need to confirm whether data has genuinely changed or is just a caching issue, create a new snapshot and compare it with your previous one. If the values differ, the source data has been updated.
