When I transform tiff from 4326 to 3857 and from 4326 to 900913 in gdal, I get different result(when display in Qgis) eventhough these two projections(3857 and 900913) should be the same. What is problem for that?
Image shows differance. Brighter(white) layer is from epsg 4326 to 3857 and darker(black) layer is from epsg 4326 to 900913. I know it's not a real standard, but in gdal gdalsrsinfo -e epsg:900913 and gdalsrsinfo -e epsg:3857 are same,I mean both have same proj.4. So I don't understand, why are layers differently displayed in Qgis.
