    In sampling spatial populations, one part of the cost is due to the distance travelled to observe all of the units in a sample. Cluster sampling is one such sampling design which is often used specifically to address this issue. Even in cluster sampling, the researcher may have to travel great distances from the cluster to cluster selected. In an optimal setting, when sampling costs are mainly a function of distance travelled, researchers could sample all of the units in the path travelled during the sampling. For this reason, the authors are ...
