Convert a RasterLayer object into a worldMatrix object or a RasterStack object into a worldArray object.

raster2world(raster)

# S4 method for RasterLayer
raster2world(raster)

# S4 method for RasterStack
raster2world(raster)

Arguments

raster

RasterLayer or RasterStack object.

Value

WorldMatrix or worldArray object depending on the input raster. Patches value are retained from the raster.

Details

See help("worldMatrix-class") or help("worldArray-class") for more details on the classes.

The number of rows and columns, as well as the cell values of the raster are kept the same. However, to match the coordinates system and resolution of a worldMatrix or worldArray, the grid is shifted by a 1/2 cell to have round coordinate values at the center of the patches and patch size is equal to (1,1). The bottom left corner cell coordinates of the worldMatrix or worldArray will be (pxcor = 0, pycor = 0).

Examples

r1 <- raster(extent(c(0, 10, 0, 10)), nrows = 10, ncols = 10)
r1[]<-runif(100)
w1 <- raster2world(r1)
plot(r1)

plot(w1)
