This function constructs an object of class "fgeo_elevation". It standardizes the structure of elevation data to always output a dataframe with names gx, gy and elev.

Usage

fgeo_elevation(elev)

Arguments

elev

One of these: A dataframe containing elevation data, with columns gx, gy, and elev, or x, y, and elev (e.g. fgeo.x::elevation$col). A ForestGEO-like elevation list with elements xdim and ydim giving plot dimensions, and element col containing a dataframe as described in the previous item (e.g. fgeo.x::elevation).

Value

A dataframe with names x/gx, y/gy and elev.
