Hello all, For the following, it will be helpful to look at http://www.GLIMS.org/datatransfer/valids.txt Last October, after the Chamonix workshop, there was discussion about how to allow more than one value in the GLIMS database for some of the WGMS glacier classification fields, such as "frontal_characteristics". As an example, a glacier front might be both "calving" and "piedmont". I propose adding extra fields to the Glacier_Dynamic table to accommodate possible additional values. So we might have something like primary_classification1 and primary_classification2. Looking at the list of six WGMS fields in the above URL, the following three fields appear to me to need an extra field: primary_classification frontal_characteristics tongue_activity Various ways were discussed to solve this problem, but I think this way is simplest, and doesn't require the end user of the data to parse sub-fields out of the database values. 1. Is it sufficient to add extra fields for just the three listed above? 2. Is it sufficient to add only one extra field to each (so that a given glacier could have two "primary_classification"s at one point in time)? 3. Any other comments? Thanks in advance for your input. If you have a general question suggestion, it's probably better to reply to the whole list, rather than just me.
