Interesting. I don't have that error (but others ;-)). There might be a problem with the certificate, and curl being not able to check it. I believe that "--config GDAL_HTTP_UNSAFESSL YES" should bypass certificate checks. Assuming this solves this issue, and you'll get the same errors as on my machine, you'll see that the server doesn't apparently accept HEAD requests (this seems to be a constant issue with S3 storage) > HEAD /test/key/value/string/object.jpg?Signature=7SPVoYI84N2YF5O0vhjvDv%2FU%2FOs%3D&Expires=1409026574&AWSAccessKeyId=AKIAJF3TTVKIEFQXGZ3Q HTTP/1.1 Host: parcel-test.s3.amazonaws.com Accept: */* < HTTP/1.1 403 Forbidden You can solve this by adding --config CPL_VSIL_CURL_USE_HEAD NO And, optionnaly, to make it faster, add --config GDAL_DISABLE_READDIR_ON_OPEN EMPTY_DIR With the last 2 applied : $ gdalinfo "/vsicurl/https://parcel- test.s3.amazonaws.com/test/key/value/string/object.jpg?Signature=7SPVoYI84N2YF5O0vhjvDv%2FU%2FOs%3D&Expires=1409026574&AWSAccessKeyId=AKIAJF3TTVKIEFQXGZ3Q" --config GDAL_DISABLE_READDIR_ON_OPEN EMPTY_DIR --config CPL_VSIL_CURL_USE_HEAD NO Driver: JPEG/JPEG JFIF Files: /vsicurl/https://parcel- test.s3.amazonaws.com/test/key/value/string/object.jpg?Signature=7SPVoYI84N2YF5O0vhjvDv%2FU%2FOs%3D&Expires=1409026574&AWSAccessKeyId=AKIAJF3TTVKIEFQXGZ3Q Size is 974, 647 Coordinate System is `' Metadata: EXIF_ExifVersion=0220 EXIF_PixelXDimension=974 EXIF_PixelYDimension=647 EXIF_Software=Google Image Structure Metadata: COMPRESSION=JPEG INTERLEAVE=PIXEL SOURCE_COLOR_SPACE=YCbCr Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0, 647.0) Upper Right ( 974.0, 0.0) Lower Right ( 974.0, 647.0) Center ( 487.0, 323.5) Band 1 Block=974x1 Type=Byte, ColorInterp=Red Overviews: 487x324, 244x162 Image Structure Metadata: COMPRESSION=JPEG Band 2 Block=974x1 Type=Byte, ColorInterp=Green Overviews: 487x324, 244x162 Image Structure Metadata: COMPRESSION=JPEG Band 3 Block=974x1 Type=Byte, ColorInterp=Blue Overviews: 487x324, 244x162 Image Structure Metadata: COMPRESSION=JPEG Even -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
