Arguments

  • product: a valid MODIS product name
  • band: band or bands (as a character vector) to download
  • lat: latitude in decimal degrees
  • lon: longitude in decimal degrees
  • start: start date
  • end: end date
  • km_lr: km left-right to sample (rounded to the nearest integer)
  • km_ab: km above-below to sample (rounded to the nearest integer)
  • site_id: site id (overides lat / lon)
  • network: the network for which to generate the site list, when not provided the complete list is provided
  • site_name: arbitrary site name used in writing data to file (default = sitename)
  • out_dir: path where to store the data if writing to disk (default = tempdir())
  • internal: should the data be returned as an internal data structure TRUE or FALSE (default = TRUE)
