dimension_values: Query coordinate values for all dimensions of a data cube

Description

Dimension values give the coordinates along the spatial and temporal axes of a data cube.

Usage

dimension_values(obj, datetime_unit = NULL)

Arguments

obj

a data cube proxy (class cube), or a data cube view object

datetime_unit

unit used to format values in the datetime dimension, one of "Y", "m", "d", "H", "M", "S", defaults to the unit of the cube.

Value

list with elements t,y,x

Examples

# NOT RUN {
# create image collection from example Landsat data only 
# if not already done in other examples
if (!file.exists(file.path(tempdir(), "L8.db"))) {
  L8_files <- list.files(system.file("L8NY18", package = "gdalcubes"),
                         ".TIF", recursive = TRUE, full.names = TRUE)
  create_image_collection(L8_files, "L8_L1TP", file.path(tempdir(), "L8.db")) 
}

L8.col = image_collection(file.path(tempdir(), "L8.db"))
