Dear GLIMS Colleagues,

With the Holiday season upon us, I offer my warmest Holiday wishes for you,
and this GLIMS Update.

(1) GLIMS Miniworkshop, San Francisco, a big success THANKS TO  MANY OF
YOU!

Rather than continue with a past practice of holding a GLIMS Lunch at the
Fall AGU, which had proven somewhat awkward at last year's meeting with
about 20 people participating, this year GLIMS launched a half-day
Miniworkshop on 12 December the day before Fall AGU in San Francisco.  The
workshop included a formal agenda component in a small meeting room at the
Marriott Hotel and then continued afterwards with informal discussions over
beer and dinner.  Among the highlights were some excellent science
presentations by several GLIMS researchers and discussions which clearly
mandated a firm new direction that you will hear more about soon:
GLIMSView will encapsulate robust glacier image analysis tools and a
much-needed standardization protocol to ensure the reliability (high
accuracy, methodological tracking, and inherent repeatability of analysis).
GLIMSView will be a standard user-friendly (and free) interface that will
link images, analyst, and database.  A previous GLIMS Update submitted by
Deborah Soltesz just prior to the Miniworkshop (available on www.glims.org)
included a release of a new GLIMSView version.  The Miniworkshop
demonstrated a maturity of candidate analysis tools used by several GLIMS
researchers and identified a large suite of analysis capabilities that
Michael Bishop (UNO) has developed; he and Deborah Soltesz (USGS/Flagstaff)
will conduct the coding of these analytical tools into GLIMSView in time
for its next released version.   Due to the maturity of these tools, and
the fact that some tools are already written in the C++ language of
GLIMSView, we expect that a subsequent release of an updated GLIMSView will
take place rather soon.  Discussed at the post-miniworkshop beer session,
and now being discussed in Flagstaff, is the further integration of
GLIMSView with ISIS, a huge existing package of analytical and image
display tools (including a capability that allows the easy generation of
large seamless image mosaics and rendering in many projections) that was
written mainly in Flagstaff for the planetary imaging and spectroscopy
community.

The GLIMS Miniworkshop was open to GLIMS and non-GLIMS participation, and a
welcome growth of the project is taking place. The lines between GLIMS and
non-GLIMS are blurring, as other people recognize the utility of the GLIMS
consortium approach and the necessity of not making it some kind of
exclusive club, which we are not and never will be.   As the structure of
GLIMS inevitably blurs somewhat, and in light of a "round-robin" analysis
test conducted (and results reported) by Bruce Raup, the need for
standardization protocols is emphasized; thus, you will see adoption in
2005 of GLIMSView as a user-friendly standardized analysis kit, compiled
for several computer platforms.  We feel that this package will become a
standard for the entire glacier remote sensing community and even some
outside the glaciology field.   The next version of GLIMSView will not
replace other analysis tools, but as the analytical capability and
flexibility of analysis (coupled with tracking of specific methodologies)
coded into GLIMSView expands, we anticipate that there will be a widespread
adoption of this package as the most reliable, most repeatable, most
user-friendly way to tackle our complex analysis tasks.

(2) USGS Develops New Gap-filled Landsat Product

Kathleen K. Gohn  (U.S. Geological Survey, Public Affairs Specialist,
Office of
Communications) has reported that USGS (not the Flagstaff office) has
completed
development of a new product enhancement for Landsat 7 Enhanced Thematic
Mapper Plus (ETM+) data captured after the Scan Line Corrector (SLC)
anomaly.  The new product will now allow the use of scenes from consecutive
passes to fill the gaps of the target scene.  The new product represents a
continuing effort by the USGS Landsat Project to increase the utility of
the Landsat 7 data affected by the scan line corrector malfunction. For
more information on the current Landsat 7 SLC-off product options, detailed
information on gap-filled processing, and to download sample products,
