Hi, One method to address this is to create a zig-zag region around the edge of each dataset, and then do a "if in region then i1 else null" type formula to display the data with a zig-zag edge. The feathering will then give a better result (the horizontal seams will be eliminated). The downside is that you have to do it by hand, which will be tedious if you have a lot of images.
The balancing wizard might be another option. cheers Mike > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Lester, Eric D Mr. > ERC > Sent: Tuesday, 10 September 2002 4:04 AM > To: [EMAIL PROTECTED] > Cc: Eric Douglas Lester ([EMAIL PROTECTED]) > Subject: Mosaic Feathering > > > All, > When mosaicking two or more images using ER Mapper the feathering function > is effective in attenuating visible "vertical" seams between the input > images.
