When I attempt to use WRITE_TIFF to save a ~0.5GB image (1-band,16384x16384 16-bit) I get allocation error from IDL on MS Win XP. I have had similar problems with WRITE_TIFF before for large images of various formats. Why does IDL need to allocate a new, larger copy of an Image before writing it? Can you suggest a work around?

Hello Guys, So far I have found that an obsolete version \RSI\IDL63\lib\obsolete\tiff_write.pro Does not crash for this image, but this version does not support GEOTIFF header.
