GeoPackage tiles layer with global extents doesn’t render

Issue Type:

BugBug

Affects Versions:

2.12.1

Assignee:

Unassigned

Attachments:

seoul-small.gpkg

Components:

geopackage

Created:

Environment:

I’m on MacOS Sierra (12.2.6) but this problem was first identified on another platform so I doubt that is the issue.

Priority:

MediumMedium

Reporter:

Jeff Yutzler

Steps to reproduce

  1. Run GeoPackage through 1.2 executable test suite to confirm it is valid
  2. Load GeoPackage into QGIS to confirm that it works when loaded directly from a file
  3. Add new store, GeoPackage (mosaic)
  4. Name it, identify a file on file system
  5. When prompted, publish its “imagery” layer
  6. Layer Preview, pick layer, choose JPG
  7. Alternatively, load layer into QGIS as a WMS or WMTS layer

Expected behavior:

  • Layer preview shows something resembling the layer
  • Layer can be loaded into QGIS properly

Actual behavior:

  • Layer preview shows up blank/white
  • When loaded into QGIS, it shows up blank/white

As far as I can tell, the issue is because this tiles layer has global extents but is sparsely populated (with the bounding box identified in gpkg_contents). This test file has six tiles in it (to make it minimally reproducible).
GeoPackages with non-global extents (e.g., https://portal.opengeospatial.org/files/?artifact_id=74983) do work as expected.
