 **Executive Summary**
 
-The International Association of Cryospheric Sciences (IACS) working group on the delineation of glaciers, ice sheets and ice sheet basins deliverable #1 aims to provide an overview of the state of ice shet delineations from some of the more common and popular products. These include basic data products used by much of the glaciological community (e.g., BedMachine), observational-derived boundaries (e.g., RGI 7.0) some regional climate model masks, etc.

 We reached out to the glaciological community ([CRYOLIST announcement](https://lists.cryolist.org/pipermail/cryolist/2022-November/008094.html)) and gathered a group of polar data experts,  producers and users. We asked our members to provide information on... and add the information to github. The following report is based on this initial consultation and contains new analyses of the presently available datasets.

 ## Discussion
 
-The masks or boundaries themseleves are rarely the primary focus of the work (with the exception of RGI, @greene_2024, and a few others). For the remaining products that are not mask-producers but rather mask-users, the decision of which mask to begin with appears to be based on reasonabe and justifiable decisions, but those decisions may be based on ease-of-use, familirarity, use of local or national products, etc. and not with significant consideration of overlap (or not) with peripheral products such as RGI, or ease-of-comparison with final downstream products.

More interesing is overlap between RGI and the 'main@' rows, which are the primary ice sheet in those products. RACMO only overlaps RGI by 10{math}`^{3.4}` km{math}`^2` (~2,500 km{math}`^2`) but most other products overlap by ~10x as much (seen by the difference between ~10{math}`^3` and ~10{math}`^4`).

 An alternative view, rather than overlap, is area of product X outside of product Y. Because overlap is commutative (X overlap Y is the same as Y overlap X) the above figure is half empty. However, X not in Y is different than Y not in X, so the following figure contains twice as much information and occupies twice the area (same information density).

-**Non-overlapping areas between masks on X axis and on Y axis in Greenland.** Scale (both number and color) is logarithmic. The diagonals are 0 because a product cannot be outside itself. An example interpretion of this graphic follows the RGI column (first column) starting at the bottom row. The bottom left square reports 10{math}`^{3.6}` km{math}`^2` (~4,000 km{math}`^2`) area of BedMachine ice shelf outside of the RGI peripheral glaciers. The second row shows the 'harper_2023' peripheral glaciers have 10{math}`^{3.7}` km{math}`^2` (5,000 km{math}`^2`) outside of the RGI peripheral glaciers. Because this graphic is log scale, a change between two values of magnitude 1 represents ~10 % of the original values, and magnitude 2 (e.g. 10{math}`^5` to 10{math}`^3`) represents 1 %.

 The above figure provide a qualitative view of overlapping masks in two regions of Antarctica. The figures below show a quantitative display of more masks and what areas of each mask either overlaps the other masks, or is outside of the other masks.
