The function retrieves the list of available Sentinel-2 products satisfying given search criteria.

s2_list(spatial_extent = NULL, tile = NULL, orbit = NULL,
  time_interval = c(Sys.Date() - 10, Sys.Date()), time_period = "full",
  level = "auto", apihub = NA, max_cloud = 100,
  availability = "ignore", output_type = "vector")

Arguments

spatial_extent

A valid spatial object object of class sf, sfc or sfg

tile

string array Sentinel-2 Tiles to be considered string (5-length character)

orbit

string array Sentinel-2 orbit numbers to be considered

time_interval

Dates to be considered, as a temporal vector (class POSIXct or Date, or string in YYYY-mm-dd format) of length 1 (specific day) or 2 (time interval).

time_period

(optional) Character:

  • "full" (default) means that all the images included in the time window are considered;

  • "seasonal" means that only the single seasonal periods in the window are used (i.e., with a time window from 2015-06-01 to 2017-08-31, the periods 2015-06-01 to 2015-08-31, 2016-06-01 to 2016-08-31 and 2017-06-01 to 2017-08-31 are considered).

level

Character vector with one of the following: - "auto" (default): check if level-2A is available on SciHub: if so, list it; if not, list the corresponding level-1C product - "L1C": list available level-1C products - "L2A": list available level-2A products

apihub

Path of the "apihub.txt" file containing credentials of SciHub account. If NA (default), the default location inside the package will be used.

max_cloud

Integer number (0-100) containing the maximum cloud level of the tiles to be listed (default: no filter).

availability

Character argument, determining which products have to be returned:

  • "online" : only archive names already available for download are returned;

  • "lta": only archive names stored in the Long Term Archive (see https://scihub.copernicus.eu/userguide/LongTermArchive) are returned;

  • "check": all archive names are returned, checking if they are available or not for download (see "Value" to know how to distinguish each other);

  • "ignore" (default): all archive names are returned, without doing the check (running the function is faster).

output_type

Character: if 'vector' (default), the function returns a vector or URLs, whose names are the SAFE names; if 'data.table', the output is a data.table with metadata.

Value

Depending on the value of argument output_type: if output_type = "vector", a vector of available products (being each element an URL and its name the product name), together with the attributes online (with the index of products available for download) and lta (with the index of products stored in the Long Term Archive) in the case availability == "check"; if output_type = "data.table", a data.table with product metadata (including the logical field online to allow distinguishing products available for download and stored in the Long Term Archive).
