## Landscape data for the Bernese Oberland around Interlaken, in the Alps of central Switzerland

### Description

Spatially-referenced data on elevation, forest cover, and water cover at a 1km-sq resolution for a 50km x 50km region in Switzerland, the Bernese Oberland. This is a small subset of the `Switzerland`

data in the unmarked package. See the Examples for a plot of the location.

### Usage

`data(BerneseOberland)`

### Format

A data frame with 2500 observations on the following 5 variables.

- x
Easting (m)

- y
Northing (m)

- elevation
a numeric vector (m)

- forest
a numeric vector (percent cover)

- water
a numeric vector (percent cover)

### Details

Forest and water coverage (in percent area) was computed using the 1992-97 landcover dataset of the Swiss Federal Statistical Office (http://www.bfs.admin.ch). Median elevation (in meters) was computed using a median aggregation of the digital elevation model of the Swiss Federal Statistical Office.

x and y are the coordinates of the center of each 1km2 pixel.

The coordinate reference system is intentionally not specified.

These data can only be used for non-profit projects. Otherwise, written permission must be obtained from the Swiss Federal Statistical Office.

### Examples

```
data(BerneseOberland)
str(BerneseOberland)
library(raster)
data(Switzerland, package="unmarked")
r1 <- with(Switzerland, rasterFromXYZ(data.frame(x = x, y = y, z = elevation)))
mapPalette1 <- colorRampPalette(c("grey", "yellow", "orange", "red"))
plot(r1, col = mapPalette1(100), axes = FALSE, box = FALSE, zlim = c(0, 4500),
main = "Location of Bernese Oberland data set")
with(BerneseOberland, rect(min(x), min(y), max(x), max(y), lwd=2))
```
