Watershed mapping and monitoring for northern community impact assessment - Clyde River, Nunavut
Bibliographic record
Abstract
This report highlights the Clyde River watershed assessment activity conducted by scientists from Natural Resources Canada. This activity included the use of high resolution satellite imagery, airphotos, and on-site field surveys to map the surrounding watershed boundaries and lake depths. This activity was also used as a technology transfer exercise, whereby local members of the community were trained to understand and use a set of tools and solutions for conducting small lake surveys and for collecting GPS locations. This document is copyright of Natural Resources Canada and contains copyrighted material of Digital Globe Inc, the provider of the Quickbird high resolution satellite image shown in this report. Digital computer files resulting from this project, and described in this document, are available for free and are grouped under the same publication file. The digital files comprise of: - Vector files of the outlines of the two watersheds (ESRI shapefile.shp). - Raster files illustrating the water depth model of each of the three lakes surveyed (Geotiff.tif) - Vector files illustrating the depth contours (isobaths) of each of the three lakes surveyed (ESRI shapefile.shp). - Tabular statistics featuring the water volume for each of the three lakes. - Lake volume statistics stored as .kml files (Keyhole Markup Language) viewable on tools such as Google Earth. - Vector files illustrating the depth contours of each of the three lakes stored as .img files compatible with Garmintm GPS map devices. - A geocoded anaglyph product illustrating the surroundings of Clyde River. This digital and printed product is georeferenced and should be viewed with anaglyph red-blue glasses.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
