Stores all the segments (geospatial arcs), which can be glacier boundaries, snow lines, internal rock boundaries, etc. Note: Glacier outline polygons, as well as internal rock polygons, are required to be closed. However, if a glacier outline was digitized as a series of segments with different attributes, then the resulting segments will be stored as separate rows in this table, and the fact that they make up a closed polygons is not explicitly stored. Closure is checked by the ingest software. Further, the ingest software imposes a vertex and segment order such that glacier outline polygons go counter-clockwise (as looking down from above), and internal rock polygons go clockwise. The analyst may digitize in any order they like, but when assigning material and feature attributes to the "left" and "right" of a segment, this ordering must be kept in mind. |

Can be one of "measured" or "arbitrary". A measured segment is the result of analysis of an image, either automatic or manual. An arbitrary segment is inserted to close the polygon when no information actually exists about the location of the boundary. This might be because a cloud obscures part of the boundary, or the image doesn't cover the whole glacier. |
