dimension_bounds {gdalcubes}

Query coordinate bounds for all dimensions of a data cube

Description

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

Usage

dimension_bounds(obj, datetime_unit = NULL)

Arguments

obj

a data cube proxy (class cube)

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, each a list with two elements, start and end

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"), quiet = TRUE) 
}
