Geomorphometry Newsletter November 2013

Our conference in Nanjing has closed 2 weeks ago. It was on the end a very smooth event with many excellent discussions and workshops (see the photo gallery). During the conference, the participants, and our international members, were asked to rate extended abstracts submitted to the programme. The current stand of papers is available via our society website. Please help us filter out the best papers by rating the papers in the programme via the geomorphometry.org website.

The submission for full-length research papers for the special issue of Earth Surface Dynamics journal is now open! We are looking for about 12-18 original research papers on topics from the Geomorphometry.org/2013 conference, but we also welcome any other contribution by the wider scientific community.ESurf is an open-access interactive journal (interactive comments are published alongside the discussion paper and will remain permanently archived, publicly accessible and fully citable) with no publication charges. It had ca 40 papers submitted in the past 6 months making it one of the most successful launches of the Copernicus journals

Geomorphometry Society meeting / E-democracy 2013

The Geomorphometry elections are held every two years during the Geomorphometry.org society meeting (Geomorphometry conference series). The results of voting (including the best paper awards and nominations for the next conference) are typically announced by the Chair and vice-Chair on the last day of the conference, and published on the society website (the website is the only official source of information).

Rules and regulations:

  1. Only full members (participated in at least one Geomorphometry.org event in the last 6 years) registered via the website are eligible to vote. The voting is done via geomorphometry.org website.
  2. Voting is anonymous, but the results are published in a table format (names are masked out). If you write down yourd IP and exact time during the voting, you can control that your vote is correct.
  3. Nominations for chair (senior staff; > 15 years of work experience) and vice chair (junior staff; <15 years of work experience) are generated automatically from the Scientific Committee list (active conference paper reviewers). The highest ranked candidates are then invited to lead geomorphometry. If the nominated candidate does not accept the task, then the next on the list is invited.
  4. The role of Chair/Vice-chair is to: (a) ensure continuity of the geomorphometry events, (b) help the local hosts with organization of the conferences and workshops, (c) regularly update members via website and newsletter (at least once in 3 months) about news and events, (d) organize society meeting and elections at least every 2 years.
  5. The deadline to vote for Geomorphometry related issues is indicated on the society website. Typically, there are no extensions of this deadline.
  6. The Chair and Vice-chair are responsible to publish the results of elections (new Chair and Vice-chair, best paper awards, nominations for the next conference) before the end of the Conference and keep the society up-to-date about any major decisions.
  7. The same Chair can only be elected for 2 consequtive elections (hence for a maximum of 4d years). The same Chair and Vice-chair can be re-elected as long as their is at least 2 years of break between the mandates.
  8. New Chair and Vice-chair can request changes to these rules. To ensure continuity of the society, each amendment needs to receive >50% votes from the Geomorphometry members at the Geomorphometry elections.

Geomorphometry Newsletter March 2013

Still working on the extended abstract for the next conference? Don’t worry: the submission deadline for Geomorphometry has been pushed to 1st of April (2 weeks extension). This is a one time extension, so please try to follow this deadline closely. The submission instructions are available here. Several people asked us about the content and length of the extended abstracts. So here are one more time main things to memorize: (1) the extended abstract MUST be between 2-4 pages, (2) try to put a more general topic for the abstract so that, if your abstract gets selected for the special issue, you can have a different title. For all other info please refer to: www.geomorphometry.org/2013

Most of keynotes and invited speakers for the upcoming Geomorphometry.org/2013 conference have been already listed on the conference website. We are happy to announce them here one more time: Ian Evans, Michael Hutchinson, Chenghu Zhou, Peter Guth, Helena Mitasova, Josef Strobl, Qinke Yang…

Learn more about our hosts at the Geomorphometry.org/2013: Nanjing Normal University have already hosted the International Science Seminar on the Terrain Analysis and Digital Terrain Stimulation (TADTM) in 2006. Later in 2008, the team participated in organizing ISPRS Summer School as well. Nanjing is an old ancient capital city of Six Dynasties, which is a key university of Jiangsu Province.

New ice-free DEM of Antartica has been recently released. This is what Antarctica will look like without all that ice »
“Stripped clean of all its ice, the polar continent exhibits a number of interesting features, including vast mountain ranges…”
