Coverage status

Current approximate Mapillary coverage across the Tournai road network.

This page keeps the original baseline visible while tracking the current state of the analysis.

The first public baseline used 11,727 Mapillary image points. It classified 151 km as covered, 71 km as partial, and 1,123 km as missing, for 11.21% covered across the analysed road network.

The current analysis includes 6,313 road segments and 1,345 km of roads. It now finds:

  • 390 km covered
  • 179 km partial
  • 776 km missing
  • 28.98% covered

The current dataset contains metadata for 62,702 Mapillary image points, with captures ranging from 2015-02-19 to 2026-06-30. When roads are split by analysis-area boundaries, the 6,313 source segments become 6,775 area-level pieces.

The current Tournai analysis unit is a little wider than the strict inside-the-boulevards target, but it is the working unit used for now. It contains 231 km of analysed road pieces.

For the street-level 360 workflow, the current QGIS layer classifies:

  • 36.00 km as full_360
  • 20.05 km as old_coverage
  • 25.30 km as partial_coverage
  • 2.35 km as to_redo
  • 147.10 km as no_coverage

The immediate field goal remains narrower than the whole unit: reach complete 360-degree coverage inside the boulevards, then expand the same method outward.

Tournai coverage quality

The map intentionally leaves roads with no detected images unstyled. It focuses on the parts of the centre where Mapillary evidence exists and distinguishes 360 coverage, front-facing coverage, freshness, and review cases.

The previous global coverage map is still exported as historical data, but it is no longer shown here because it mixed a simpler point-density model with the newer street-level 360 model.
