Swiss landscape data
Spatially-referenced data on elevation, forest cover, and water at a 1km-sq resolution.
data(Switzerland)
A data frame with 42275 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)
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 metres) 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 intentionally not specified.
