Summary

In the latest places release (2026年05月20日.0), a significant number of points are geolocated in the ocean (off any landmass). Comparing the same geographic area against an older release (2024年02月15日-alpha.0), the regression is clearly visible: the older release shows only a handful of off-land points, while the new release shows widespread ocean coverage across the Atlantic, Mediterranean, and other water bodies.

Affected release

• 2026年05月20日.0

Reference release

• 2024年02月15日-alpha.0

Steps to reproduce

1. Load the places theme from release 2026年05月20日.0.
2. Visualize the point geometries on a map.
3. Zoom to Western Europe / North Atlantic / Mediterranean.
4. Observe a large number of points scattered over open ocean.
5. Repeat with release 2024年02月15日-alpha.0 for comparison — the same area is essentially clean.

Expected behavior

Place points should fall on (or very near) landmasses, matching the spatial distribution seen in 2024年02月15日-alpha.0. A small number of legitimate offshore points (oil platforms, ports, lighthouses, ferries, etc.) is expected, but not the dense ocean coverage currently observed.

Actual behavior

A significant portion of points in 2026年05月20日.0 are located in the ocean, with no apparent landmass association. The pattern looks systematic rather than the result of a few isolated bad records. When looking at these place taxonomies, the vast majority are not legitimate offshore points (eg, furniture_store, contractor, or garbage_collection_service).

Evidence

• Screenshot 1: 2026年05月20日.0 — Western Europe / North Atlantic view, showing widespread ocean points.

• Screenshot 2: 2024年02月15日-alpha.0 — same area, showing clean land-bound distribution.
