Aaron's Solution, Instructor's Problem: Teaching Surface Analysis Using GIS
Bibliographic record
Abstract
Teaching GIS is relatively simple, a matter of helping students develop familiarity with the software. Mapping as an aid to thinking is harder to instruct. This article presents a laboratory and lecture package developed to teach the utility of mapping in a course on spatial data analysis. Following a historical review of the use of surface mapping in medicine, it investigates a recent outbreak of salmonella. The lab teaches two different analytic techniques, hierarchical buffers and a surface kerneling approach. The result is a historically grounded program in which different means of address are compared and considered by students.

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.
