Query scenes from CODE-DE EO Finder API

Description

Returns metadata for satellite imagery that matches several input criteria

Usage

getScenes(
  aoi,
  bufferDist = NULL,
  startDate = NULL,
  endDate = NULL,
  codede = TRUE,
  satellite = NULL,
  productType = NULL,
  sensorMode = NULL,
  orbitDirection = NULL,
  relativeOrbitNumber = NULL,
  view = FALSE
)

Arguments

aoi	Area of interest for the query. Has to be an sf object with polygonal or point geometry. In case of a point geometry, the buffer argument has to be set.
bufferDist	Buffer around the AOI in meters. Defaults to 0.
startDate	Starting date for the query of format "YYYY-MM-DD".
endDate	End date for query.
codede	If TRUE (default) use CODE-DE repository covering Germany, if FALSE use CREODIAS for worldwide coverage including Landsat data.
satellite	Satellite to query from. One of "Sentinel1", "Sentinel2" etc. If none is chosen, all available results are returned.
productType	Product type to query. One of "SLC", "GRD", "CARD-INF6", "CARD-BS", "CARD-BS-MC", "L3-WASP"... Only considered if set.
sensorMode	Sensor mode for Sentinel-1. One of "IW", "EW", ... Only considered if set.
orbitDirection	Direction of satellite orbit. One of "ascending" or "descending". Only considered if set.
relativeOrbitNumber	Relative orbit number. Only considered if set.
view	logical indicating if the queried scenes should be visualized with mapview. Defaults to FALSE.

Value

sf object containing footprints and metadata for all queried scenes.

Examples

# example AOI
aoi <- c(10.441054, 52.286959) %>%
  sf::st_point() %>%
  sf::st_sfc(crs = 4326)

# scenes for aoi and given criteria
scenes <-
  getScenes(
    aoi = aoi,
    startDate = "2019-01-01",
    endDate = "2019-01-15",
    satellite = "Sentinel1",
    productType = "SLC",
    view = TRUE
  )
