Reuse data from storage

How to reuse images downloaded via data blocks, archive and satellite tasking orders


Introduction

This article shows you how to reuse satellite images that you previously purchased either via data blocks, archive ordering or satellite tasking operations.

Important

Please note that only data provided by Airbus can be reused.

Recommended

This feature is intended for advanced users and it requires basic familiarity with JavaScript Object Notation.

Data reuse methods

When ordering Airbus archive images or satellite tasking images, each image retrieved gets a unique asset ID. The same is the case when running a job for the first time using a data block. The newly-generated asset ID is displayed on the Storage, along with the data ready to get downloaded. For more information, please refer to Storage.

Based on the generated asset IDs, UP42 provides 2 methods for reusing images: use asset IDs in Processing from Storage (recommended) and use asset IDs in data blocks. The difference between the 2 methods is explained in the table below.

1. Use asset IDs in Processing from Storage

To reuse the image using the block Processing from Storage, please follow the steps below:

  1. Go to Storage.
  2. In the dashboard, locate the asset name, then scroll to the right.
  3. Click on the first grey circle and click Image Information.

  1. Scroll to the right and copy the asset ID under Asset Identifier.

  1. Create a new workflow and add the block Processing from Storage. For more information about building workflows, please refer to Building your first workflow.

  1. In the job configuration window, find the parameter asset_ids and paste the asset ID in an array. For more information about jobs, please refer to Job Configuration.
  2. You don’t need to adjust the JSON parameters of the following processing block (see example below).
  3. Click Run Job.
  4. Done.

Example with the processing block Pan-sharpening and multiple asset IDs:

Useful tip

Please note that you can also add more asset IDs in the form of an array, where each item is separated by a comma. Example: ["3475e76d-4e04-420e-a683-bc4831df824f", "d266389c-798c-42b5-a164-721caed9b0c5"].

Please note that the capabilities between this block and the following processing blocks cannot be verified. We recommend exploring the capabilities of the corresponding dataset. For instance, the SPOT 6/7 Display or Reflectance product will have different compatible blocks.

2. Use asset IDs in data blocks

Currently, the data blocks that generate asset IDs are shown in the table below.

To reuse the image using data blocks, please follow the steps below:

  1. Go to Storage.
  2. In the dashboard, locate the asset name, then scroll to the right.
  3. Click on the rightmost grey circle to copy the asset ID. Please note that only the assets with metadata have this grey circle and can be added in the workflow.

  1. Use an existing workflow or create a new workflow and add the corresponding data block that matches the satellite image you previously downloaded. For more information about building workflows, please refer to Building your first workflow.

  1. In the job configuration window, find the parameter asset_ids and paste the asset ID in an array. For more information about jobs, please refer to Job Configuration.
  2. You don’t need to adjust the JSON parameters of the following processing block (see example below).
  3. Click Run Job.
  4. Done.

Example with the data block Pleiades Display (Download) and the processing block DIMAP→ GeoTIFF Conversion:

Good to know

This functionality relies on the presence of the file data.json, which contains the asset metadata. This file is generated during data retrieval through data blocks.

Useful tip

Please note that you can also add more asset IDs in the form of an array, where each item is separated by a comma. Example: ["3475e76d-4e04-420e-a683-bc4831df824f", "d266389c-798c-42b5-a164-721caed9b0c5"].
