Import Images after a Search

The following code shows how to import the results of a search to a workspace.

Prerequisites

To run this code you need:
  • A running Python 3.x Environment
  • A valid WASDI Account
  • A valid Config file
  • A valid params.json file

If this is not clear, you probably need to take a look to the Python Tutorial before.

Recipe

Note

We will use Sentinel-1 for this sample but the same code can be used for all the missions and image types.

Note

In the code, you will see different options. Most likely, you will want to choose the one that best fits your needs.

This is our sample params.json file.

{
    "START_DATE": "2023-01-01",
    "END_DATE": "2023-01-01",
    "BBOX": {
    "northEast": {
        "lat": 20.1,
        "lng": 44.4
        },
    "southWest": {
        "lat": 19.3,
        "lng": 43.2
        }
    },
    "MISSION": "S1",
    "PRODUCT_TYPE": "GRD"
}
# Read Bounding Box, Start and End Date
oBBox = wasdi.getParameter("BBOX", None)
sStartDate = wasdi.getParameter("START_DATE", "2023-01-01")
sEndDate = wasdi.getParameter("END_DATE", "2023-01-31")

# Read Mission and Product Type
sMission = wasdi.getParameter("MISSION", "S1")
sProductType = wasdi.getParameter("PRODUCT_TYPE", "GRD")

# Search Images
aoProductsFoundArray = wasdi.searchEOImages(sMission, sStartDate, sEndDate, sProductType=sProductType, oBoundingBox=oBBox)

# OPTION 1: Import a single image and wait for the image to be available
if len(aoProductsFoundArray) > 0:
   wasdi.importProduct(aoProductsFoundArray[0])

# OPTION 2: Import a single image WITHOUT waiting for it:
if len(aoProductsFoundArray) > 0:
   sProcessId = wasdi.asynchImportProduct(aoProductsFoundArray[0])
   # Here you can do what you want
   wasdi.wasdiLog("Started Import of one image, the associated process id is " + sProcessId)
   # Call this if you need to wait
   wasdi.waitProcess(sProcessId)

# OPTION 3: Import All Products and wait for the images to be available
wasdi.importProductList(aoProductsFoundArray)

# OPTION 4: Import All Products without waiting
sProcessId = wasdi.asynchImportProductList(aoProductsFoundArray)
# Here you can do what you want
wasdi.wasdiLog("Started Import of all images, the associated process id is " + sProcessId)
# Call this if you need to wait
wasdi.waitProcess(sProcessId)

What it does:

  • Reads Input Parameters
  • Starts searching for S1 GRD Images
  • Imports 1 Product
  • Asynchronously imports 1 Product
  • Imports All Products
  • Asynchronously imports all Products
