raster_cube_dummy: Create a dummy data cube with a fill value

Description Usage Arguments Value Note Examples

View source: R/dummy.R

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

1
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.
