This is a thorough, detailed and well written design and description of the new Austrian Glacier Inventory (AGI5).

I question the value of 10-25cm orthophotography for glacier mapping - one could not identify extent to this precision even if one was in situ, and with summer melt, it would change on a daily/weekly basis - these images were captured over two summers (2022-23). However this is the resolution of the available imagery !

The round robin experiment is curiously interesting but I note that the analyst variability far exceeds the image resolution.

I identify some very minor graphic issues in the otherwise excellent figures:

Figure 1: there is no need to add 0' in each graticule label - this is simply 'noise'

Figure 7: it seems inconsistent to shorten the labels on the Vanishing Glaciers to GI3,GI5 when even in the caption, they are written in full: AGI3, AGI5 etc..

Supplementary material: the scale bar divisions on figures should be standard/round numbers e.g. 50,100 rather than 40, 45, 0.45, 0.26, 70 etc.. (figures S1,2,4,5,9)
