Stephen,
Landsat has been the corner stone for vegetation mapping since it became
available in the early 1970s. Vegetation change, depending on specific
questions can certainly be addressed using this technology. Given that the
spatial resolution is 30 meters, change detection below this is not
feasible with Landsat imagery, However, for synoptic landscape scale
questions it has proven itself to be very useful and informative.
I suggest you look at literature by Dr. Marvin Bauer and his colleagues who
have worked with change detection for some time. Check out the Journal
Remote Sensing and the Environment for articles, Dr. Bauer is (was) the
editor for this journal.
Without a more detailed understanding of what you are trying to accomplish,
I am not able to offer more specific directions. However, you may want to
look at change vector analysis methods, spectral change detection, and
other aspects of remote sensing that focus on the spectral information in
the remote sensing imagery.

Has anyone had success with using Landsat data for measuring vegetation
change over time? I'm finding that the detail is not fine enough and the
frequency is not short enough for what I am trying to do. I'm not an
expert, so I was curious to hear from others who have been successful
accessing/using the data.
Thanks,
Steve
