obtain (spatial) resolution of a stars object

obtain resolution(s) of a stars object: by default only the (absolute) x/y raster dimensions, optionally all delta dimension parameters

Usage

st_res(x, all = FALSE, absolute = !all)

Arguments

x: an object of class stars
all: logical; if FALSE return a vector with the x/y raster resolution
absolute: logical; only works when all = FALSE; if TRUE return absolute resolution values, if FALSE return delta values

Value

if all = FALSE a vector with x/y raster resolutions, otherwise a list with delta values

Examples

st_res(L7_ETMs)
#>    x    y 
#> 28.5 28.5 
st_res(L7_ETMs, absolute = FALSE)
#>     x     y 
#>  28.5 -28.5 
st_res(L7_ETMs, all = TRUE)
#> $x
#> [1] 28.5
#> 
#> $y
#> [1] -28.5
#> 
#> $band
#> [1] NA
