sits_cube: Defines a data cube

In e-sensing/sits.data: Satellite Image Time Series Data Handling

Description

Defines a cube to retrieve data. Cubes are associated to data services. The following services are available:

• "WTSS": Web Time Series Service - used to get time series

• "SATVEG": SATVEG Time Series Service - used to get time series

• "EOCUBES": EOCUBES service - cloud processing of data cubes

• "BRICK": Raster Brick files

• "STACK": Raster Stack files

Usage

sits_cube(
  service = "BRICK",
  URL = NULL,
  name = NULL,
  satellite = NULL,
  sensor = NULL,
  tiles_names = NULL,
  geom = NULL,
  from = NULL,
  to = NULL,
  timeline = NULL,
  bands = NULL,
  files = NA
)

Arguments

service	Name of the data service.
URL	URL of the service provider.
name	Name of the data cube in the remote service.
satellite	Name of satellite
sensor	Name of sensor
tiles_names	Tile names to be filtered (for EOCUBES service)
geom	An sf object to filter tiles (for EOCUBES)
from	Starting date for the cube to be extracted
to	End date for the cube to be extracted
timeline	Vector with the timeline of the collection (only for local files)
bands	Vector of bands.
files	Vector of file names for each band (only for raster data).

Examples

{
# Example 1. Create a data cube based on a WTSS service
cube_wtss <- sits_cube(service = "WTSS", name = "MOD13Q1")

# Example 2. Create a data cube based on the SATVEG service
cube_satveg <- sits_cube(service = "SATVEG", name = "terra")

# Example 3. Create a raster cube based on bricks
# inform the files that make up a raster brick with 392 time instances
files <- c(system.file("extdata/raster/mod13q1/sinop-crop-ndvi.tif",
           package = "sits.data"))

# create a raster cube file based on the information about the files
raster.tb <- sits_cube(name  = "Sinop-crop",
             timeline = timeline_modis_392, bands = "ndvi", files = files)

# Example 4. create a coverage from EOCUBES service
modis_cube <- sits_cube(service = "EOCUBES", name    = "MOD13Q1/006")
 # get information on the data cube
modis_cube %>% dplyr::select(service, URL, satellite, sensor)
# get information on the cube
modis_cube %>% dplyr::select(xmin, xmax, ymin, ymax, timeline)
}
