A new method for the mapping of the relative locations of organisms as points in a 2—dimensional space is presented. The proposed method is based on a least—squares estimate of the coordinates using observed distances between the objects being mapped (rather than triangulation based on horizontal angles). Only a small subset of the possible interpoint distances need be measured in order to obtain a very accurate map. The method is applied to 3 problems in mapping of trees in a forest.
