Define Google Earth Engine data to collect

Usage

collect_ee(
  collection = NULL,
  coords = NULL,
  date = NULL,
  end_date = NULL,
  buffer = NULL,
  bound = FALSE,
  config = NULL
)

Arguments

collection: string: name of a Google Earth Engine collection. Collections can be found on the Google Earth Engine Catalog
coords: numeric: GPS coordinates in WGS84 [East, North]. Minimum of one set of coordinates should be provided to create a point coordinate. If more than one set of coordinates is provided, a polygon will be created
date_min: string Start date to download in YYYY-MM-DD, e.g. 2019-10-01
date_max: string End date to download in YYYY-MM-DD, e.g. 2019-11-01
buffer: integer, optional: If coords is a single point, buffer can be used to create a circular buffer with the specific radius in metres. If coords contains more than one set of coordinates, this argument does nothing
bound: logical, optional: If buffer contains an integer value, this agrument will convert the circular buffer to a bounding box instead. Defaults to FALSE
config: string, optional: Path to a configuration file in .yaml format. When this is provided, all arguments are ignored and the function will refer to the configuration file to determine argument values

Value

an object containing attributes necessary to preprocess and and download images for all other *_ee() functions

Examples

if (FALSE) {
collect_ee(
  collection = "LANDSAT/LC09/C02/T1_L2",
  coords = c(149.769345, -30.335861, 149.949173, -30.206271),
  date = "2021-06-01",
  end_date = "2022-06-01"
)
}
