CanTopo Map Standards and Specifications 1:50 000
Bibliographic record
Abstract
The CanTopo Map Standards and Specifications 1:50 000 are a description of all features and information shown on a Canadian Topographic map produced by the Collections Management and GeoInformation Division (the former Centre for Topographic Information Ottawa) of Natural Resources Canada since 2009. This includes a definition of each map feature, instructions on how each feature is compiled and a description of the cartographic symbols used to represent each map feature. Also described in this document is how "non feature" information is to be depicted on a Canadian Topographic map. This information includes the map legend, scale, border and grid as well as notes describing the magnetic declination, map projection and contour interval. This publication is often referred to as the CanTopo Specs and provides the user with a comprehensive description and illustration of all features and information portrayed on a Canadian Topographic map at a scale of 1:50 000. Before 2009 the 1:50 000 Topographic maps produced by Natural Resources Canada used the "National Topographic System (NTS) Polychrome Map Standards and Specifications".

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.
