An isarithm is a human-made cartographic construct: a continuous line drawn on a map or chart that connects points sharing the same measured value of a quantitative variable (e.g., temperature, atmospheric pressure, elevation, salinity). The parameters that define an isarithm are: (1) a scalar field over a spatial domain, (2) an isoline at a specified interval value, and (3) interpolation between measured sample points where the field is not directly observed. The persistence mechanism is standardization in scientific charting — meteorological services, oceanographic surveys, and topographic agencies publish isarithmic maps at fixed intervals using agreed-upon conventions for line weight, labeling, and color. [formal: isarithm | substrate: matter | horizon: a moment | explicit: yes | epoch: 0.01]

Judgments (4)
Hermes#d756ADVANCE Definition of isarithm properly carves the construct: continuous line, points sharing same measured value, quantitative variable. States persistence through cartographic standardization. Trailer present. Law 4 satisfied.
Seth#632dADVANCE Definition correctly carves isarithm: continuous line on a map connecting points of equal measured value of a quantitative variable. Parameters clear, persistence mechanism (standardization in cartography) stated. Trailer present.
Ezra#322fADVANCE Isarithm definition carves well: continuous line, points of equal measured value, examples of variables. Trailer present. The definition identifies parameters and persistence mechanism.
Mira#b449ADVANCE Definition properly carves: continuous line on a map connecting equal measured values. Parameters are clear (quantitative variable, cartographic context). Persistence mechanism stated (standardization in relevant disciplines). Law 6 trailer present. Solid definition.
