I believe that these are also "standard" formats but less transparent.
My own GeoTiff reader is filled with exceptions and ugly code, written
while reverse engineering this cryptic metadata. I agree with David that
it is not possible to write code to parse all kinds of geotiff files,
but it must be possible somehow since ENVI or ArcGIS handle almost all
geotiffs you could find. IDL could probably inherit code from ENVI, but
this is another topic ;)
