Hi all,
I was just perusing the gdalwarp page on www.gdal.org/gdalwarp.html,
when I noticed this tautological sentence:
"Mosaicing into an existing output file is supported if the output file
already exists."
Any idea what it is meant to say? I presume it is something to do with
the bounds of an existing output file being used instead of those of the
input.
John,
It means if the output file already exists then it will be mosaiced into
as opposed to a new file being created. It isn't just the bounds of the
existing file that are utilized - the whole file is used and the only
thing altered is the pixels replaced as part of the warp/mosaic operation.
I don't think the statement is tautological, but it does seem to be less
than clear, and perhaps a bit redundant.
Best regards,
