Some info we're missing with regard to the Specim instruments:

• datasheets for the specific CCDs used (so we know the behaviour and characteristics of the CCD, particularly in regard to overflow handling and smear correction)
• per pixel FOV
• CCD response curves (per pixel? or from datasheet)

Current TIFF formats are limited to 2GB, which is an issue with the Eagle & Hawk - large numbers of bands can easily exceed this limit.

Bill says that ERDAS 9.2 supports BigTIFF (and perhaps big geotiffs as a result?). It'd be good to find out the extent of the support and perhaps implement BigTIFF support in azexhdf.

This ticket is to track the issue for now. At some point we may want to take action on it.

Arrange this with Victoria @ NEODC. Probably all that needs doing is ensuring that PIs are signed up for NextMap at NEODC. Verify this is the case and that it's ok to distribute DEMs to them then.
