So how are we to determine what is garbage inĪ given context for a given type of analysis?

In, garbage out” mantra applies ever more strongly when differentials andĮspecially higher order derivatives are concerned. However, we really need to recognize-as a community-that the “garbage So I am not discouraging that to theĬontrary. WE WANT TO INCLUDE/EXPAND IN THE GLIMSĭATABASE MULTITEMPORAL DATA ON GLACIER STATE AND DYNAMICS. Used, for example, satellite multispectral vs. Then simply the average rate of change over a given satellite-era timeĪnd second derivatives of change, we need a new focus on error analysis ,īecause obviously errors mount the more one deals with the higher orderĮven more problematic is when completely different types of datasets are There is a lot of interest in this matter,Īnd we should pursue it, but obviously the greater importance has to beĪttached to completing the single-snapshot global coverage for GLIMS/RGI and Of acceleration or deceleration of glacier changes. (A careful reading of what’s in the GLIMSīook assures the reader that even all that is rich with challenges.) A further level of challenge is in assessment

Straight forward to do first-order change assessment, such as Cosi-CorrĪnalysis of flow speeds or manual or semiautomatic assessment of glacierįrontal retreat or advance, and a little more challenging (or impossible in Like ASTER-to-ASTER, the problems (including error analysis) are relatively Multitemporal coverage we have to consider how such data will be used forĭifferential analysis, first-order derivatives and second-order. With his emphasis on multitemporal coverage. That will include shoehorning in the RGI but has to go beyond that.

Right now, I have a full private room reserved for 30 people at Henry’s Hunan Restaurant. If we have more than 30 people expected to attend, I need to know soon to reserve a different space.
