GLIMS: Global Land Ice Measurements from Space

Monitoring the World's Changing Glaciers

GLIMS Workshop 2008, Boulder, Colorado, USA (Original announcement and info page)

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:

  1. DEM generation from satellite stereo pairs

  2. Mapping ice divides

  3. Mapping debris covered glaciers

  4. Challenges in assessing change through comparisons with older data

  5. 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:

  1. What are the best tools and methods for the problem? How can these be best shared with the GLIMS community?

  2. Where are the main problems? What steps need special attention?

  3. What additional methods or algorithms need to be developed?

  4. Can we agree on specific protocols, definitions or procedures to help the GLIMS community deal with this topic?

  5. 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.

Anticipated Workshop Results

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.

Registration

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.

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
