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.
• Figure 1 and Table 1 (No. 3) in Nikitin et al. 2000 (http://www.webgeo.ru/books/MGI/88.pdf, page 145), Figure 2 in Surazakov et al. 2007 (https://doi.org/10.1088/1748-9326/2/4/045017), Figure 1 in Narozhniy & Zemtsov 2011 (https://doi.org/10.1007/s13280-011-0166-0) suggest that RGI incorrectly names RGI60-10.01708 "Vodopadniy Glacier" when it should be "Kar Malogo Aktru Glacier".
• RGI60-07.00230 is named "Finsterwalderbreen" but should be named "Leinbreen" (according to https://data.npolar.no/placename/dd5a7ecd-50d0-5447-84e7-3b12f376867e).
• 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.
• Figure 1 in Zhang et al. 2014 (https://doi.org/10.1016/j.quaint.2013.08.035) suggests RGI60-13.45344 should be named "CN5Y730C0026", not "CN5Y730C0025".
• Figure 1 in Zhang et al. 2014 (https://doi.org/10.1016/j.quaint.2013.08.035), Figure 5.1 in Chen 2014 (https://doi.org/10.1007/978-94-017-8017-9) suggest RGI60-13.45336 should be named "CN5Y730C0030", not "CN5Y730C0031". best, ethan

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

Moving this to the GLIMS issue tracker.

Actually I'm not sure. This should be checked in RGI 7.0 and/or GLIMS to see if this is still an issue.
