Austria Glaciers



Austria Glacier Database Field Descriptions

PHOTO_YEAR
Description: The 4-digit year of the photograph used for measurements of Austria glacier parameters. Note: If more than one photograph were used, the most relevant year is recorded here; and the others used are recorded in the REMARKS field. In general, the Austria glaciers outlines; and hence, the values for area and length; were determined from Austria aerial photographs, so we recommend using the PHOTO_YEAR for glacier area values.
No Data Value: Null
Example: 1976

MAX_ELEV
Description: Maximum elevation of the highest point of the Austria glacier in meters above sea level, up to 4 digits.
No Data Value: Null
Example: 3962

MEAN_ELEV
Description: The mean elevation is the altitude of the contour line, in meters above sea level, that halves the area of the glacier, up to 4 digits.
No Data Value: Null
Example: 3170

MIN_ELEV
Description: The minimum elevation of the lowest point of the glacier in meters above sea level, up to 4 digits.
No Data Value: Null
Example: 1590

FORM
0 Miscellaneous Any type not listed below.
1 Compound Basins Two or more individual valley glaciers issuing from tributary valleys and coalescing.
2 Compound Basin Two or more individual accumulation basins feeding one glacier system.
3 Simple Basin Single accumulation area.
4 Cirque Occupies a separate, rounded, steep-walled recess which has formed on a mountain side.
5 Niche Small glacier in a V-shaped gully or depression on a mountain slope; generally more common than genetically further-developed cirque glacier.
6 Crater Occurring in extinct or dormant volcanic craters.
7 Ice Apron Irregular, usually thin ice mass which adheres to mountain slopes or ridges.
8 Group A number of similar ice masses occurring in close proximity to one another but are too small to be assessed individually.
9 Remnant Inactive, usually small ice masses left by a receding Austria glacier.

FRONT_PROF:
0 Miscellaneous Any type not listed below.
1 Piedmont Ice field formed on a lowland area by lateral expansion of one or coalescence of several glaciers.
2 Expanded Foot Lobe or fan formed where the lower portion of the glacier leaves the confining wall of a valley and extends on to a less restricted and more level surface.
3 Lobed Part of an ice sheet or ice cap, disqualified as an outlet glacier.
4 Calving Terminus of a glacier sufficiently extending into sea or lake water to produce icebergs; includes- for this inventory- dry land ice calving which would be recognizable from the "lowest glacier elevation."
5 Confluent Coalescing, non-contributing.
6 Irregular, mainly clean ice (mountain or valley glaciers).
7 Irregular, mainly debris-covered (mountain or valley glaciers).
8 Single lobe, mainly clean ice (mountain or valley glaciers).
9 Single lobe, mainly debris-covered (mountain or valley glaciers).
