I have a GeoTIFF file for which gdalsrsinfo reports this:
PROJ.4 : '+proj=utm +zone=32 +datum=WGS84 +units=m +no_defs 'OGC WKT
ROJCS["WGS 84 / UTM zone 32N",GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0, AUTHORITY["EPSG","8901"]], UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","9122"]], AUTHORITY["EPSG","4326"]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",9],PARAMETER["scale_factor",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["metre",1, AUTHORITY["EPSG","9001"]],AXIS["Easting",EAST],AXIS["Northing",NORTH],AUTHORITY["EPSG","32632"]]If I try to import that file into Tilemill, I cannot view it properly. If I chose to let Tilemill autodetect the SRS, it fails:
Unable to determine SRS for layer "antani2" at /home/strappanai/antani2.tiffIf in Tilemill I specify a Custom PROJ.4 string instead, that is, the one I get from gdalsrsinfo (and from QGIS as well), that is
+proj=utm +zone=32 +datum=WGS84 +units=m +no_defs
then the layer actually gets imported, but it is showed significantly tilted to the right - not as expected.
I don't know if this may matter to any extent, but QGIS imports and visualizes the file perfectly fine.
I also try to reproject the source file as instructed here: https://www.mapbox.com/tilemill/docs/guides/reprojecting-geotiff/
But gdalwarp returns this error a thousand times and then fails:
ERROR 1: Too many points (441 out of 441) failed to transform,unable to compute output bounds.Warning 1: Unable to compute source region for output window 3593619,2225230,6394,6394, skipping.More than 1000 errors or warnings have been reported. No more will be reported from now.
