## Topographic Data for CTFS Plot : Elevation, Convexity and Slope

### 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)

### Format

A list with 2 components:

col
  dataframe of x, y coordinates and elevation
x
  a numeric vector, location on East-West axis, in meters
y
  a numeric vector, location on North-South axis, in meters
elev
  a numeric vector, elevation in m
mat
  matrix of the `elev`

### Details

These data are used to make topographic maps and to compute mean topographic values for quadrates. This data set contains the same information as `bcielev.info`.
