A stratified survey design method that selects sampling points in a given territory using environmental and spatial distances as surrogates of overall diversity. The procedure minimises the variation uncovered by the selected points using a set of consecutive criteria repeated iteratively. In each iteration, a p-median allocation criterion is used to define a vector of preselected sites, then a set of user defined conditions is applied to restrict the preselected sites so that one location is selected in each iteration.
