Extract metadata from rasters in zip and tar.gz/bz2 archives #43

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Add ability to extract metadata from rasters in zip and tar.gz/bz2 archives now 
that this is handled transparently (for some formats...) in GDAL.

Might take a while, listing archive contents is easy, but there's lots of code 
in the format drivers (and base Dataset class) that assumes they are handling a 
regular file - i.e 
os.path.exists(r'C:\ExistingDir\ExistingZipFile.zip\image.tif') will always 
return False.

And for those formats that GDAL doesn't support at all, or doesn't support 
transparent access to via the /vsizip/ and /vsitar/ virtual filesystems, the 
only option is to uncompress/extract. I don't think this is workable, in this 
case it will either be flagged in the log or the output spreadsheet.

This issue was updated by revision r643.

Enhancements to enable listing archive contents. Add archivelist function and 
modifies rglob class.

This issue was updated by revision r644.

Enabled metadata extraction from zip/tar archives for generic gdal supported 
formats. Untested on custom formats yet. No handling of errors trying to read 
such formats other than the usual logging.
