# Intro to WorldView Radar Tasking

note

WorldView Radar tasking is in limited release and is not currently available to all accounts.

## Overview[​](#overview "Direct link to Overview")

WorldView Radar is part of the Vantor virtual constellation. With access to WorldView Radar Tasking, Hub subscribers can now task [Umbra](https://umbra.space)’s synthetic aperture radar (SAR) satellites for all-weather intelligence in ultra-high resolution.

info

Only SAR Spotlight imaging modes are currently available.

### Credits and usage[​](#credits-and-usage "Direct link to Credits and usage")

Pricing is per scene (5km x 5km image footprint) and based on tasked resolution and dwell duration.

A usage quote is calculated when a request is submitted. Account credits are reserved to cover the quoted amount. Once the order is fulfilled, any reserved credits that were not used are released.

## Quoting and placing Tasking orders[​](#quoting-and-placing-tasking-orders "Direct link to Quoting and placing Tasking orders")

The following endpoints can be used to estimate tasking credit use, and to submit the tasking request:

| Request                                                                 | Endpoint                              | Description                                                             |
| ----------------------------------------------------------------------- | ------------------------------------- | ----------------------------------------------------------------------- |
| [Quote a tasking order](/docs/tasking/api/quote-a-tasking-request)      | `/tasking/umbra/estimate`             | Returns estimate data for credits consumed for the request.             |
| [Submit an Umbra tasking order](/docs/tasking/api/submit-umbra-tasking) | `/tasking/umbra`                      | Submit your Umbra tasking request                                       |
| Validate a Tasking Request                                              | `/tasking/umbra?validation_only=true` | add the path parameter `validation_only=true` to validate your request. |

See also the [Umbra](/docs/tasking/guides/example-umbra-sar.md) example.

### Collection window (start and end date)[​](#collection-window-start-and-end-date "Direct link to Collection window (start and end date)")

The collection window for an Umbra tasking request can start immediately and must end at most 364 days in the future.

### Area of interest[​](#area-of-interest "Direct link to Area of interest")

Imaging location must be submitted as a GeoJSON Point. A 5x5 km image footprint containing this point will be delivered.

### Tasking parameters and options[​](#tasking-parameters-and-options "Direct link to Tasking parameters and options")

The tasking parameters and output options are described in the [Umbra](/docs/tasking/guides/umbra-parameters.md) parameter page.

### Order deliveries[​](#order-deliveries "Direct link to Order deliveries")

Once imagery is collected, ordered, and processed, it can be delivered to the following cloud storage platforms:

* Amazon S3 commercial cloud
* Azure cloud storage
* Google cloud storage

Tasking V2 does not currently support the `download` option but this delivery method is planned to be reinstated.

The order is also delivered to the Orders Manager in the [Hub User Interface](https://hub.vantor.com).

Delivery details are also included in the status messages found in the Tasking response object. See [Delivery details](/docs/tasking/guides/tasking-status.md#delivery-details).

> Note for AWS S3 users: V2 APIs deliver to S3 from a new ARN. If you have previously delivered to S3 from the Ordering API or Tasking V1 API, you will need to add an additional ARN to your bucket policy. The updated bucket policy can be found [here](/docs/ordering/guides/cloud-storage-setup/amazon-s3.md#iam-policy-grants).

See [Ordering Output Delivery Options](/docs/ordering/guides/outputs.md) for more detail.
