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.
