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)

Value

list with elements t,y,x

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.

Examples

# create image collection from example Landsat data only 
# if not already done in other examples

  create_image_collection(L8_files, "L8_L1TP", file.path(tempdir(), "L8.db"), quiet = TRUE) 
}
