I'm confused because of the representation of mbtiles files in QGIS. It seems that the whole grid is shifted by about 3 m to the south. Fig.

So far I can observe this behavior only in the context of QGIS and mbtiles. Maybe somebody comes up with an idea?

For reverse engineering: Load Geotiff in Tilemill and export as mbtiles. Load both files in QGIS.

On the search for the cause I have

  • generated the mbtiles file with geoscript-groovy: same result -> Tilemill does not seem to be the cause.

  • taken an other GeoTIF -> same result: shifted 3m south.

  • loaded the mbtiles-file in MapProxy, published it as WMS and loaded it in QGIS -> fits perfectly: the mbtiles file itself it seems so not to be the cause.

    What latitude is this? Could it be a 4326 / 3857 difference? – BradHards Dec 21 '14 at 21:06
  • What is the the spatial reference of your source tiff? Does the problem occure if you use vector data? – Devdatta Tengshe Dec 22 '14 at 5:15
