Hi list,<div><br></div><div>I have been struggling the last hours, trying to find out the origin of a small shift (around 10m NE) I detected in tiles origin on a MBTiles files generated with Tilemill. In the attached picture I overlay the shapefiles (in wgs84) used on the mbtiles file generation.</div>
<div><br></div><div>My MapProxy grid config looks like this:</div><div><br></div><div>....</div><div><div>grids:</div><div> GRID_SA_256_Google:</div><div> srs: 'EPSG:3857' </div><div> bbox: [-20037508.342789236,-20037508.342789236,20037508.342789236,20037508.342789236]</div>
<div> tile_size: [256, 256] </div><div> res: [156543.033928,78271.516964,39135.758482,19567.879241,9783.939621,4891.969810,2445.984905,1222.992453,611.496226,305.748113,152.874057,76.437028,38.218514,19.109257,9.554629,4.777314,2.388657,1.194329,0.597164,0.298582,0.149291] </div>
</div><div><br></div><div>Is this grid valid? I googled around for the default values for Google/OSM grid specifications.</div><div><br></div><div>Thanks,</div><div>-- <br><div>Fernando Ribeiro</div><br>
