Pull spatial data from google earth engine (GEE) for a given region on any feature in the google earth engine database

Description

Pull spatial data from google earth engine (GEE) for a given region on any feature in the google earth engine database

Usage

gee_datapull(
  email = "[e-mail]",
  gee_boundary = "users/ifeanyiedochie/gadm36_CMR_0",
  gee_polygons = "users/ifeanyiedochie/cmr_polypop_boundary",
  gee_dataname = "NOAA/VIIRS/DNB/MONTHLY_V1/VCMSLCFG",
  gee_datestart = "2018-01-01",
  gee_dateend = "2018-01-31",
  gee_band = "avg_rad",
  scale = 100,
  gee_desc = "nighttimelight_cmr",
  gee_stat = "mean",
  gdrive_folder = "/SAEplus",
  ldrive_dsn = "data/cmr_nighttimelight",
  gee_crs = "EPSG:4326",
  tileScale = 1
)

Arguments

email	A GEE authenticated gmail address
gee_boundary	A shapefile with the boundaries for a specific region/country for which data is to be collected
gee_polygons	A polygon shapefile spanning the region in the gee_boundary file for features will be computed. forms the unit of analysis
gee_dataname	The specific google earth engine collection dataset name (use default as example) see (https://developers.google.com/earth-engine/datasets/) for full name
gee_datestart	The starting date for the specific feature of interest
gee_dateend	The ending date for the specific feature of interest
gee_band	The bandname within the gee_dataname selected (see https://developers.google.com/earth-engine/datasets/)
scale	Used in mean region reduction for zonal statistics
gee_desc	The name to be used to name output in google drive as well as local drive
gdrive_folder	Google Drive folder name to be created or uses if already existing to store shapefile output
ldrive_dsn	Full file path (including shapefile name) for local storage of resulting shapefile
gee_crs	Set CRS
gee_image	if TRUE, an image rather than an image collection is expected (FALSE by default)

Value

shapefiles to local drive
