Description Usage Arguments Details Value Functions See Also Examples

These functions provides the basic operations over a cube (EOCubes_cube) object.

cube(name, remote = default_remote())

cube_name(cube)

cube_remote(cube)

cube_bands(cube)

cube_bands_info(cube)

cube_crs(cube)

cube_bbox(cube)

cube_raster_info(cube)

cube_dates_info(cube)

cube_filter(cube, tiles = NULL, from = NULL, to = NULL)

`name`	A `character` text with cube name.
`remote`	An `EOCubes_remote` object.
`cube`	An `EOCubes_cube` object.
`tiles`	A `logical` or `integer` vector indicating which tile to be selected. If `NULL` (default) all tiles are selected.
`from`	A `Date` value to filter layers' dates.
`to`	A `Date` value to filter layers' dates.

The function cube_extent access the metadata field 'extent' of an EOCubes_cube object that contains xmin, ymin, xmax, and ymax values.

The function cube_raster_info access the metadata field 'raster' of an EOCubes_cube object that contains size (pixels) and resolution (CRS units per pixel) values.

The function cube_dates_info access the metadata field 'interval' of an EOCubes_cube object that contains from and to dates interval that encompass cube layers values.

The parameter tiles of the function cube_tiles can be used with tiles_which function.

An EOCubes_cube object.

A character string.

A character vector.

An EOCubes_bandlist object.

A character string.

A list object.

An EOCubes_cube object with tiles that satisfies the which criteria.

x <- remote("localhost")
cub1 <- cube("MOD13Q1/006", x)
cube_name(cub1)   # show the entry name 'MOD13Q1/006'
cube_remote(cub1)   # show the remote entry name 'localhost'
cube_bands_info(cub1)   # show bands and its meta data
cube_crs(cub1)   # show CRS string
cube_bbox(cub1)   # show bbox values
cube_raster_info(cub1)   # show raster size and pixel resolution
