Subject: [Glacierdata] Issues in RGI / GLIMS
While fixing incorrect glacier centerpoint coordinates in
GlaThiDa (https://gitlab.com/wgms/glathida), I identified some issues in RGI 6.0
(which in some cases may also translate to GLIMS):
Nordlicher Schneeferner, Austria (RGI60-11.03246, no GLIMS equivalent) is
positioned east of the actual glacier. The OpenStreetMap polygon (likely
from an official government source), in contrast, is in close agreement with
satellite imagery.
RGI incorrectly names glaciers on "Rainer Island" (Franz Josef Land, Russia)
as "Rainier Island".
RGI incorrectly names glaciers on "Wilczek Land" (Franz Josef Land, Russia)
as "Hall Island'.
According to Figure 2 in Satylkanov 2018
(https://doi.org/10.3233/JCC-180009), RGI60-13.06359 is incorrectly named
"Karabatkak Glacier", which is actually RGI60-13.06361.
RGI60-01.16316 spans a divide. According to Figure 1 in Clarke & Collins
1984 (https://doi.org/10.1139/e84-032), the east-facing half is known as
"Hazard Glacier".
RGI60-10.01730 spans a divide, joining two isolated (and separately-studied)
glaciers.
Blauschnee, Switzerland (47.25037, 9.34300) and the other ice masses on
Säntis not included in RGI, but included in GLIMS.
Schwarzmilzferner, Austria (47.29796482, 10.29691371) not included in either
RGI or GLIMS.
Glacier de Tsarmine, Switzerland (46.04691948, 7.52034926) not in RGI, but
included in GLIMS.
RGI version RGI v6

Expected outcome Names and IDs should be fixed. Many will be fixed in the GLIMS Glacier Database.
