Request vegetation index statistics from the Data Space Statistics API

Description

Request vegetation index statistics from the Data Space Statistics API

Usage

pa_get_vi_stats(
  aoi,
  start.date,
  end.date,
  collection = c("sentinel-2-l2a"),
  vegetation.index = c("bsi", "evi", "gcvi", "ndre", "ndvi", "reci"),
  agg.time = c("P1D", "P5D", "P10D"),
  by.feature = FALSE
)

Arguments

aoi	sf object used to filter satellite products
start.date	beginning of the time window to filter satellite products. Date format should be '%Y-%m-%d'.
end.date	end of the time window to filter satellite products. Date format should be '%Y-%m-%d'.
collection	for now, it only supports 'sentinel2'.
vegetation.index	vegetation index to be requested from the Data Space
agg.time	aggregation time of the satellite products
by.feature	logical, indicating whether the statistics should be retrieved by each polygon when multiple polygons are supplied in ‘aoi’

Details

'pa_get_vi_sentinel2()' will use HTTP requests to communicate with the Data Space Statistics API and request areal statistics for the specified vegetation index

Value

returns an object of class veg.index and stars
