GLIMS Minimum Requirements list

[Bruce Raup]

Hello all.

At the GLIMS workshop in Maryland I was tasked with circulating to the
glims_database list, then to the RCs, a list of minimum requirements for
submission of GLIMS data to NSIDC.  Here is a draft of that list.

Please have a look and send any comments or questions you have --
preferably to the list, but to me personally if you're shy.  :-)

The following is a Minimum Requirements list for submission to the GLIMS
glacier database by a Regional Center.  Insertions of historical data into
the GLIMS database will not necessarily require all of these fields, as
they might not exist.  But any new submission of data derived through
remote sensing methods should include the following.

Minimum requirements for GLIMS database entry

 - Glacier ID (lat & lon of "center"; this point should be on centerline of
   the glacier)
 - Glacier outline (collection of segments and attributes)
 - Coordinate system (ellipsoid, or projection parameters) for glacier
   outline
 - Whether image from which outline was derived was orthocorrected
 - Data source (image ID and instrument ID, or, for older inventories, map
   name and date ,...)
 - Source analyst (RC name and ID, person name)
 - time of analysis (NOTE:  time of observation can be recovered thru image
   ID)
 - processing description

Desireable

 - scalar parameters, such as
     - mean width
     - length
     - snow line elevation
     - lowest elevation
     - highest elevation
 - Centerline
 - Tie-point region polygon(s)
 - (pointer to?) Associated DEM
 - References to relevant literature
