Barro Colorado Island Quadrat Descriptions
Description
Topography-derived variables and UTM coordinates and UTM coordinates of a 50 ha sample plot (consisting of 50 1-ha quadrats) from Barro Colorado Island of Panama. Dataset BCI provides the tree species composition (trees with diameter at breast height equal or larger than 10 cm) of the same plots.
Usage
data(BCI.env)
Format
A data frame with 50 observations on the following 6 variables.
UTM.EWUTM easting
UTM.NSUTM northing
elevationmean of the elevation values of the four cell corners
convexmean elevation of the target cell minus the mean elevation of the eight surrounding cells
slopemean angular deviation from horizontal of each of the four triangular planes formed by connecting three of its corners
aspectEWthe sine of aspect
aspectNSthe cosine of aspect
