I have a set of old black and white airphotos that we scanned in house more than 16 years ago. They are signed 16 bit Tiffs. When I loaded them into SDE 9.3.1 to publish as an images service, I had to convert them to 8 bit unsigned or they would just appear as all grey with one value in all the cells. Well, now I am trying to load them into a raster dataset on a SQL Server based 10.3.1 Enterprise Geodatabase, and I'm getting the same results. But it seems like with 10.3.1 I am offered many more options on the kinds of images I can load. Is it possible, if I find the correct options, to load this data, or will I have to convert them again to 8 bit unsigned?
A sample image is too big to attach here, but should show up here ftp://yakimagis:PomonaPasturefirstname.lastname@example.org/BadTif in a few minutes.
