GLIMS: Global Land Ice Measurements from SpaceMonitoring the World's Changing Glaciers |

See also this synopsis page.
Dear GLIMS RCs, Stewards, and affiliates,
As many of you know, there have been several highly successful GLIMS Workshops over the past 8 years in such locations as Switzerland, Maryland, France, Norway, England, and New Zealand, and some smaller meetings in Italy, California and Arizona. It has been 7 years since there has been a GLIMS workshop in the United States with significant international participation. We are therefore planning on holding a GLIMS workshop in Boulder, Colorado, as described in detail below.
GLIMS Workshop
Boulder, Colorado
June 16-18 (Monday-Wednesday), 2008
Duration: 2.5 days (half day on Day Three)
Through this workshop we seek to review and advance the current state of knowledge regarding several key topics that are of direct relevance to glacier studies based on remote sensing. These are:
DEM generation from satellite stereo pairs
Mapping ice divides
Mapping debris covered glaciers
Challenges in assessing change through comparisons with older data
Other major hurdles in satellite glacier mapping
Workshop participants are invited to make presentations that address specific questions related to one or more of these topics, such as:
What are the best tools and methods for the problem? How can these be best shared with the GLIMS community?
Where are the main problems? What steps need special attention?
What additional methods or algorithms need to be developed?
Can we agree on specific protocols, definitions or procedures to help the GLIMS community deal with this topic?
What additional assistance can be provided to help make dealing with this topic easier for others in GLIMS?
This workshop will address GLIMS-specific issues mostly at the technical level. By contrast, the International Workshop on World Glacier Inventory, to be held in Lanzhou, China, 20-24 September 2008, will focus on the broader issues of coordinating different glacier inventory efforts, how these efforts tie into larger Earth observation programs, and how best to achieve global coverage soon.

*Speakers will be assigned soon according to topic relevance.
The results of the workshop will be compiled into a report, with intent to submit it for publication. In addition, a section of the www.glims.org Web site will show the results of these working groups and disseminate algorithms and computer code.
There will be food brought to the site for continental breakfasts and lunches. To cover these costs, there will be a registration fee of $60, payable on-site. Receipts will be provided.
Please let us know (e-mail to Bruce Raup and Richard Armstrong) as soon as possible if you plan to attend this workshop so that we may start on the necessary organizational tasks that will be required at NSIDC.
Should you decide to attend, you may find this logistical information helpful.
Note: If you drive, we can supply parking permits. Please park in metered spaces for a short time when you first arrive. After you receieve a parking pass, park in any "EC" lot.
You are free to choose from hotels found via the above link. Also, the Best Western Boulder Inn has given us a conference rate. Details:
Boulder has a continental climate, with large differences between day and night temperatures. See this National Weather Service page for forecasts.
On Sunday, 15 June, a few of us plan to go for a hike in the mountains, hopefully to get a closer view of a Colorado glacier. (To see Colorado glaciers, you need to get up close to them.) This may involve hiking to elevations around 3600 m. If you're interested in joining us, let Bruce Raup know by June 7.
Post-hike BBQ and ice-breaker:
WHEN: Sunday evening (June 15th), 6 ~ 9 pm
WHERE: Family housing community center, 33rd + Colorado, Smiley Court,
next to NSIDC
ADDRESS: 1300 30th St, Boulder. See Map.
WHAT: This will be an informal ice-breaker/BBQ open to all participants. We
will have a grill, some items to grill, and a cash bar for drinks. If you
are interested in attending, please express your interest by June 10 to Adina Racoviteanu, and
any food/drinks preferences, so that we know how much food to provide.
CONTACT: Adina
Racoviteanu, ph: 720-422-2850 (best way to reach on Sunday afertnoon in
case you get lost).
And a few of our favorites:
