Commercial Land Use: Dispersed Stores
Bibliographic record
Abstract
This map shows how commercial activity is distributed within urban areas and the impact of commercial services on the urban landscape, by mapping what proportion of stores (hence jobs) in an urban area that are found in dispersed stores. The dispersed stores are those activities that are left out when all the commercial polygons in the city have been mapped. They include the traditional activities such as service stations and convenience stores, as well as clusters of stores that are too small to qualify as commercial polygons. In most cities, some 30% of stores are assigned to this category, with higher proportions in small cities and slow-growth cities. Since dispersed stores seldom serve consumers living outside the city, they tend to be relatively more important in cities with low indices of centrality. Like arterial strips, they may also be an indicator of weaker planning legislation that permits commercial activity outside designated commercial zones. The distribution of dispersed stores shows cities with low proportions in the Prairie and Maritime provinces, and cities with higher values in Ontario and Quebec.

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.
