R: Create a dummy data cube with a fill value

raster_cube_dummy {gdalcubes}

R Documentation

Create a dummy data cube with a fill value

Description

Create a data cube with a constant fill value for one or more bands from a data cube view. Use this cube for testing.

Usage

raster_cube_dummy(view, nbands = 1, fill = 1, chunking = c(16, 256, 256))

Arguments

`view`	a data cube view defining the shape (spatiotemporal extent, resolution, and spatial reference)
`nbands`	number of bands
`fill`	fill value
`chunking`	vector of length 3 defining the size of data cube chunks in the order time, y, x.

Value

a proxy data cube object

Note

This function returns a proxy object, i.e., it will not start any computations besides deriving the shape of the result.

Examples

v = cube_view(extent=list(left=388941.2, right=766552.4, 
                         bottom=4345299, top=4744931, t0="2018-01", t1="2018-12"),
             srs="EPSG:32618", nx = 497, ny=526, dt="P1M")
L8.cube = raster_cube_dummy(v, 1, 2.345)

plot(L8.cube, zlim=c(0,4))
