Description

A list composed of two objects. One is a data frame of x, y coordinates and elevation at that point. The second is the same data in a matrix format. The grid size is 5 x 5 m.

Usage

data(bcitopo.info)

x
a numeric vector, location on East-West axis, in meters
y
a numeric vector, location on North-South axis, in meters
