It is intended for situations in which a geometric pattern is first observed and then formally <br>assessed. Point-to-curve deviations are used to compare the observed configuration with alternative <br>spatial and geometric arrangements subject to specified constraints.The framework is demonstrated <br>using a summit landscape in Central Bosnia, where a constrained logarithmic curve pattern has been <br>proposed to link a small set of named summit locations derived from LiDAR data. The observed <br>configuration occupies an extreme position relative to alternative constrained configurations within <br>the defined summit set.The analysis is limited to spatial geometry and does not address origin or <br>interpretation.
