Hi Catherine,

  Sounds like a fun project. We could probably use a little more info on
what kinds of features you want to track. Do the dunes stand out clearly
from other features? Do they have a common shape? Are you working with
color or grayscale images? How do you define "dune" vs "not dune" in the
images? It might be helpfull if you could provide some example imags.
I'm sure ImageJ is capable of measuring what you want to know. Just be
sure to provide a little more detail on what exactly you want to
measure. Also, how many images are you planning to ananlyze. Is it few
enough that it will be reasonable to do a few steps by hand?

Cheers,
Damon

I've been trying to do this with IMAGEJ, but am finding it difficult. Does anyone know a way to track the migration of an entire dune using IMAGEJ? Does anyone have experience with tracking image changes? Thanks!
