Locational models are being used with increasing frequency in geographic information systems. Many such models use distance measurements in calculating solutions. A number of commonly used distance measurement procedures are used to examine whether results are influenced by the various estimates. In one set of analyses, the objective function increases with the scale factor of the source map. Additionally, the geometrical configurations yielded by the analyses vary among the distance estimation procedures.
