Resources for past and present mapping of glaciers in the Western Cordillera
Bibliographic record
Abstract
The Western Canadian Cryospheric Network (WC2N) is funded by the Canadian Foundation for Climate and Atmospheric Sciences (CFCAS) until 2010 to study the glaciers of the Western Canadian Cordillera, under three themes focusing on past and present glacier extent and climate variability, meteorological and climate processes, and modelling changes in glacier cover and runoff. The co-investigators and collaborators are located in six western Canadian universities along with the Universities of Washington, Western Washington, and federal institutions. This talk will present the data sources we have used in monitoring glacier extents since the Little Ice Age Maximum. These involve a combination of aerial photography, historic mapping, satellite imagery and digital map datasets, to establish both glacier extents, and elevations from contours and digital terrain models. This work has incorporated the scanning of several thousand aerial photographs from provincial and federal archives, the acquisition of early twentieth century maps, Landsat, SPOT and ASTER satellite imagery covering the cordillera over multiple dates, and both provincial and national topographic data.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
