| Description: | Special Report Abstract: Accuracy and speed of property estimating of randomly dispersed populations can be improved by identifying and accounting for the influence of shape of both the element and the viewing stage. Perimeter intercept count of high density non-overlapping dispersions provides a rapid method of density evaluation, provided the influence of shape on location and orientation of elements and on the random definition of the intercepts is recognized. The efficiency of the circular stage is seen to be due to its randomizing of intercepts. Models demonstrate these influences and comparative accuracy of three systems of estimating. |
