|Tools for this tag|
The tag glacier:part=* describes a part of a glacier where some attributes are different from the rest of the glacier. Polygons with glacier:part=* should either be within a separate natural=glacier area representing the entire glacier or - in case of the Antarctic - within the implicitly mapped ice sheet. The purpose of this tag is similar to that of building:part=*.
How to map
To map a small part of a glacier with distinct properties you can just draw a line closing on itself along the outline of the area and tag it glacier:part=*. To map large glaciers you can use Relation:multipolygon with the same tag.
|glacier:part=blue_ice||Part of a glacier or icesheet without snow cover due to ablation exceeding precipitation but without substantial ice melt. Common occurrence on the antarctic ice sheet, not for mountain glaciers. See|
|glacier:part=moraine||Part of a glacier or icesheet covered by scree from rockfall from surrounding rock faces, which is transported with the moving glacier, often in form of a medial moraine. See geological=moraine and surface=scree.. Useful combinations are|
|glacier:part=icefall||Steep and strongly crevassed section of a glacier. See|
|glacier:part=crevassed||General crevassed section of a glacier without the crevasses individually being mapped with natural=crevasse|
|glacier:part=yes||Unspecified glacier part with properties defined by other tags|
