dimension_values {gdalcubes} | R Documentation

## 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

    # 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"))
    v = cube_view(extent=list(left=388941.2, right=766552.4,
                  bottom=4345299, top=4744931, t0="2018-04", t1="2018-06"),
                  srs="EPSG:32618", nx = 497, ny=526, dt="P1M")
    dimension_values(raster_cube(L8.col, v))
