Hi - Is there anyone out there who has worked on an algorithm to fill gaps in
Landsat ETM+ SLC-Off data? Now that the Landsat 7 archive is freely available
I am looking for an open source approach to fill the gaps in the SLC-Off data
and GRASS seems like a good option. I'm most interested in multi-date approaches
but at this stage I'm looking at single-date approaches as well. Any ideas?

I had just downloaded new Landsat 7 SLC-Off data. It still useable
for land use change analysis. A grass tool would be very helpful.
cheers,

Some ideas here:
http://grass.osgeo.org/wiki/MODIS#Removing_holes
both single scene interpolation (r.fillnulls) and rolling composite using a time series (r.patch) methods are explained.
