Locations and sizes of Longleaf pine trees.
A marked point pattern.
The data record the locations and diameters of
584 Longleaf pine (Pinus palustris) trees
in a 200 x 200 metre region in southern Georgia (USA).
They were collected and analysed by Platt, Evans and Rathbun (1988).
This is a marked point pattern; the mark associated with a tree is its
diameter at breast height (
dbh), a convenient measure of its size.
Several analyses have considered only the ``adult'' trees which
are conventionally defined as those trees with
greater than or equal to 30 cm.
The pattern is regarded as spatially inhomogeneous.
