Abstract

Guided transect sampling is a two-stage sampling design in which prior information is used to guide the field survey in the second stage. In the first stage, broad strips are randomly selected and divided into grid-cells. For each cell a covariate value is estimated from remote sensing data, for example. The covariate is the basis for subsampling of a transect through the broad strip. The general idea of guided transect sampling can be combined with different transect-based field inventory methods. This paper describes guided transect sampling and provides some results from a theoretical evaluation.
