[gdal-dev] .asc files during open

[Todd Smith]

When opening .asc files, they are scanned for any values that may be
floating point so the type of data (int or float) can be set properly.  For
the case I'm dealing with (2800 files @ 50mb each) it means that each file
takes about 1.25 seconds to open (because the data is all integer data).  It
means it takes nearly an hour for all the files to be opened.  Short of
changing the code to not scan for a '.' and just assume that every file is a
floating point file, can anyone think of a good way to speed this up?

Thanks,

Todd
