Description of the water depth survey and other geomatics datasets for Arviat, Nunavut
Bibliographic record
Abstract
A bathymetric map, and water related statistics of a lake close to the city of Arviat where produced following field work performed during the summer of 2009 by researchers from Canada Centre for Remote Sensing in collaboration with staff from the Nunavut Research Institute. This field survey also permitted the acquisition of other geomatic datasets Since 2007, with support from Indian and Northern Affairs Canada (INAC), a small team of scientists from the Canada Centre for Remote Sensing were involved in a project to help characterize the water supply of Nunavut communities. This is a complex task involving the delineation of watersheds and estimation of the water volume of the supply lake for the community. To estimate this water volume, a bathymetric map is produced based on field surveys using a depth sounder equipped with a GPS. CCRS developed a low cost and easy to use technique to enable such depth surveys to be rapidly carried out. The technology transfer aspect of the activity is aimed to allow Nunavut professionals to produce lake depth maps with low cost and easy to use tools and software. During the course of this project, between 2007 and 2009, these initiatives allowed researchers, engineers, managers, planners and technical personnel to perform lake and watershed surveys of the communities of Iqaluit, Clyde River, Whale Cove and Arviat. This document describes the digital datasets acquired for Arviat and distributedto the Department of Community and Government Services, the Nunavut Research Institute, and the Department of Indian and Northern Affairs. The enclosed datasets were produced under the ''Enhancing Resilience in a Changing Climate Program'' of the Earth Sciences Sector, Natural Resources Canada. Several large format image maps were printed and distributed to the organisations identified above, and were also presented at several workshops.

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.
