[Gdal-dev] ERMapper .ers ?

[Brent Fraser]

Frank,

ERMapper has a free C library available (different from the ECW SDK).  It
allows reading of ".ers" and ".alg" files.  From my little dabbling that
I've done with it, the C api should fit into the GDAL architecture without
too much pain.  The doc is fairly poor, but there are a couple of example
apps included with SDK.
