Today, 64-bit (x64) raster processing is released in ERDAS
IMAGINE 2014. All raster formats which support x64 processing with in Spatial
Modeler, Spatial Modeler (Legacy), MosaicPro, Export ECW, and more. Because much
of ERDAS IMAGINE uses Spatial Modeler (Legacy) for processing, a very wide
swath of the product processes raster data in true x64. There are a few very
old raster formats that depend on third-party libraries, where the third party
has not ported to x64, and these raster formats will run in x86.
Once example ECW Exporter, I ran a test yesterday.... I copied a 22GB file using the DOS cmd.exe 'copy' command. It took longer to copy the 22GB file from local disk to the same local disk than it took to compress the 22GB image file with the ECW Exporter. So, speed is one benefit of x64 bit processing (as if we did not know that already).
Another example, Image Segmentation... with
the x64 processing we released a new version of image segmentation. I will cover
that in another blog post at a later time.

Hi Paul
I just had the chance to test this release and I found this 'bug' that could be easily fixed (I think!). When I do a subset using an AOI, ERDAS adds a blank row of pixels with value 0 at the top of the file. I don't really mind having that row added, but the values in that row should be NoData instead of 0. I just had to do another subset using file coordinates to remove that row, since the NoData value in my files is different than 0.
Well, thanks for providing this space!
Was your image an ortho image or a calibrated image?
