lsEspaGetOrderImages: Gets a first response from ESPA regarding a recent request

In spatialstatisticsupna/RGISTools: Handling Multiplatform Satellite Images

Gets a first response from ESPA regarding a recent request

Description

lsEspaGetOrderImages obtains the identification number and the status of the request from the EROS Centre Science Processing Architecture (ESPA).

Usage

lsEspaGetOrderImages(
  username = NULL,
  password = NULL,
  c.handle = NULL,
  order.list = NULL,
  verbose = TRUE
)

Arguments

username	USGS's ‘EarthExplorer’ username.
password	USGS's ‘EarthExplorer’ password.
c.handle	a curl handler created with the package 'curl' to stablish a connection with a preset password and username. This argument is mandatory if username and password are not defined.
order.list	a list of orders from lsEspaOrderImages
verbose	logical argument. If TRUE, the function prints the running steps and warnings.

Details

This function is part of a group of functions used to pre-process Landsat level-1 images. The pre-processing is carried out by ESPA on demand. lsEspaGetOrderImages takes the identification (ID) number of a request carried out by lsEspaOrderImages. This ID is used to follow up the processing status with lsEspaUpdateOrders. All the status messages and their interpretation can be found in the ESPA's API User Guide.

Examples

## Not run: 
wdir <- file.path(tempdir(),"Path_for_downloading_folder")
# search Landsat 7 level-2
sres <- ls7Search(startDate = as.Date("01-01-2017", "%d-%m-%Y"),
                  endDate = as.Date("07-01-2017", "%d-%m-%Y"),
                  lonlat = c(-1.64323, 42.81687),
                  AppRoot = wdir)
# request to ESPA the pre-pocessing of level-2 images to
# get the surface reflectance
order <- lsEspaOrderImages(search.res = sres,
                           username = "username", 
                           password = "password", 
                           product = 'sr',
                           verbose = FALSE)
# get an ID for our request
lsEspaGetOrderImages(username = "username", 
                     password = "password")
