get the raster type (if any) of a stars object

st_raster_type(x, dimension = character(0))

Arguments

x

object of class stars

dimension

optional: numbers or names of dimension(s) to get per-dimension type

Value

if dimension is not specified, return the spatial raster type: one of NA (if the object does not have raster dimensions), "curvilinear", "rectilinear", "affine", or "regular". In case dimension(s) are specified, return one of "regular", "rectilinear"

(irregular but numeric), or "discrete" (anything else).

Details

categories "curvilinear" and "affine" only refer to the relationship between a pair of spatial (raster) dimensions.

Examples

tif = system.file("tif/L7_ETMs.tif", package = "stars")
x = read_stars(tif)
st_raster_type(x)
#> [1] "regular"
st_raster_type(x, 1:3)
#>          x          y       band 
#>  "regular"  "regular" "discrete"
