IMO:
Michael, Again, I don't pretend to be an expert on JPEG2000. However, I'd like to know more about the format for future reference. Does the wiki article at the following URL represent a good overview of the format? http://en.wikipedia.org/wiki/JPEG_2000 If it is accurate, there is a section that leads me to conclude that the format is not suitable for a lot of remotely sensed spatial imagery: <snip> "Color components transformation Initially, images have to be transformed from the RGB color space to another color space, leading to three components that are handled separately. There are two possible choices:..." </snip> If this *is* the case, then I wouldn't be able to use the format to store multi and hyper spectral imagery (ignoring other JP2 issues). As to what format are we using currently: The source format that the data came in with appropriate Geophysics, ERMapper and in some cases Erdas Imagine conversions. What are we using in the future: To be determined, probably a database oriented solution. As to data corruption: Many image processing algorithims and processes result in data loss. The aim for most people is to understand what is acceptable and to minimise the corruption of their data. In our situation, some of the imagery may result from many millions of dollars spent in capture and processing. Much of it is irreplacable. All of it must be protected for future use.
