Ready to begin?

We need an email address so we can let you know when your data is ready, and send you an invoice.

We'll also join you up to where your data and farm boundaries will be stored. If you're already a member, you can use this site without a password, but we'll ask for one if you want to order PAStack for an existing farm.

More about this

The PAStack website steps you through

  • making a new farm (or choosing an existing one)
  • uploading/drawing/editing paddock boundaries
  • and finally paying for your order.

Once your order has been filled, it's also where you'll come to work with your data.

The website is also good for creating a basic farm map - you don't have to proceed to payment. You can download your boundaries (and do many other things) using PASource. PAStack's sister site, has a similar process for ordering regular Landsat imagery for a growing season or year, for now or back to 2013.

Signing up

We need your email address so that we can send you an emails with links to access your images, and a copy of your invoice (if applicable). We'll also join you up to where your data and farm boundaries will be stored. Membership is free, and will give you access to your image archive at any time. PASource will also give you tools to print, interrogate and share your historical images. Terms and conditions can be found at the bottom of this page.

If you create a new farm using PAStack, you'll receive an email providing options to add/edit your boundaries, and access your membership. If you don't receive the email soon after signup, please check your junk folder.

If you've used PAStack before and want to set a password, put in your email address, click 'check', select 'use a farm in PASource', and click the orange 'Set password' button.


Like any satellite imagery, the Landsat imagery used in PAStack can be affected by cloud. If an image is partly affected by cloud we will provide it but alert you to cloud being present. It's also possible that scattered clouds can escape the cloud detection algorithm. It is your responsibility to judge whether an image has been affected by cloud, and hence how useful it is. Look for the cloud warning messages when you load a cloud-affected image, and the yellow background when a cloud affected image is in a list.

If there is heavy cloud cover we will not provide the image as it unfortunately has no value.

When your imagery email arrives

As data is provided for your farm, you'll receive notifications via email. You'll need to use the link in your original email, or log in here to access and 'stack' images, create zones, and download images and zones.

If your 'Landsat Archive' emails haven't arrived within a week of ordering, please check your 'promo' or 'spam' folders. If your order has been submitted correctly, you should receive an invoice email within half an hour of payment.
