International audienceWe investigate the meaning of the mathematical properties of distances in the fields of geography and economy. The key property for spatiality is the triangle inequality (TI) as ensurring the optimality of distance. We identify three different situations where several authors identify violations of the TI. We consider all of them as errors of interpretation.The first error consists in considering sub-optimal measurements as distances. Yet distances are necessarily optimal since they respect the TI.The second set of error, which is the most widespread, involves a confusion between the Euclidean straight line and the minimum path. The errors consist in considering the presence of a detour as a violation of the TI, while ...
