[MapServer-users] Fwd: WMS with a GPKG-based layer : different responses, dependending on version (1.1.1 vs 1.3.0)

[Philippe Ghesquiere]

Hi Jukka,

Our GPKG (osm_4326.gpkg) contains OSM tiles, with an InspireCRS84Quad
<https://gdal--13880.org.readthedocs.build/en/13880/drivers/raster/gpkg.html#tiling-schemes>
tiling scheme. The pyramid goes from Z=0 down to Z=13.
In the Mapfile, the layer's DATA is coming from the MapCache WMTS layer
(i.e. the GPKG file).

Mapfile excerpt :
LAYER
   NAME "osm_4326"
   METADATA
     "wms_title" "OpenStreet Map WMS"
   END
   TYPE RASTER
   DATA "baselayers_gdal_osm.xml"
   PROJECTION
      "init=epsg:4326"
   END
END

baselayers_gdal_osm.xml content:
