Every method in this hub owns a jurisdiction. Pick your sample’s form, its support state, the direction you need measured, its characteristic scale, its electrical character, and the temperature range — the six-question selector returns the geometry-native primary method, the credible alternates, and the reason, with links into the deep-dive articles. The map above places the principal method families by the sample scale they were built for.
Logic: a jurisdiction-first decision tree distilled from the method articles in this hub — geometry decides the family, electrical character decides the in-family variant (direct Joule heating vs coating vs optical heating), temperature range flags special provisions. Recommendations are starting points for a feasibility review, not a substitute for one. Links open the corresponding deep dives.
