Simulated ForestGEO-style stem table for tests
geo_example_stems.RdReturns a small stem inventory in local metre coordinates (gx, gy)
for trying plot_topo(). Columns follow the ForestGEO convention
(plot, treeID, stemID, gx, gy, dbh, species, status).
Positions, sizes and species are simulated on a 100 m x 100 m plot to
check code only. They are not real Wanang or ForestGEO trees: do not
present maps or results from this table as field data.
