DEA Tech Alerts
Keep up with the latest updates, releases, outages, and planned maintenance.
Warning: DEA near-real-time data not up-to-date. See below.

In progress: Shift in origin point of DEA Summary Product Grid
To accommodate an expanded area of coverage of Australia’s external territories, the DEA Summary Product Grid is being shifted. The south-west origin point of the grid is being shifted from -5472000.0, -2688000.0 to -6912000.0, -4416000.0 (EPSG:3577). Therefore, all tile grid references will shift 18 tiles west and 15 tiles south. For instance, a tile reference of x10y10 will change to x28y25. For a preview, see the provisional version of the expanded DEA Summary Product Grid on DEA Maps. Download the new grid from AWS S3
All new versions of our ‘summary derivative products’ will be affected by this change (but existing versions of the products will not be changed).
It has already been applied to the latest versions of the following products: DEA Geometric Median and Median Absolute Deviation (Landsat), DEA Water Observations Statistics (Landsat), DEA Fractional Cover Percentiles (Landsat), DEA Tasseled Cap Percentiles (Landsat), and DEA Mangroves (Landsat).
It will be applied to the new version of the following product when released: DEA Land Cover (Landsat)

12 Mar 2025: Landsat near-real-time (NRT) data outage (6 March to the present) due to planned USGS maintenance and a subsequent issue
Planned USGS maintenance caused DEA’s Landsat near-real-time (NRT) data to experience downtime. This planned maintenance occurred from 6 March to 9 March (UTC); however, a subsequent issue in our (DEA’s) own data systems has caused the outage to continue to the present time. We are currently working on the issue and expect it to be resolved by the end of the day.

20 Feb 2025: DEA near-real-time data not up-to-date
DEA near-real-time ARD datasets are currently not up-to-date. We are investigating the cause of this issue.

The DEA Sandbox is currently unavailable. We are currently working to restore the service.
21 Jan 2025: Sentinel-2A data switching over to Sentinel-2C
Digital Earth Australia’s Sentinel-2A data products will stop publishing data updates on 21 January 2025. They will be replaced with equivalent Sentinel-2C data products, which will begin publishing data shortly after. For further information on the precise timing of the transfer, please see Sentinel Online. The historical Sentinel-2A data will still be provided as public data. A new ga_s2cm_ard_3 product will begin receiving data for both our NRT and definitive offerings within the coming weeks.
8 Jan 2025: DEA Maps data not up-to-date (Resolved)
DEA Maps and OWS layers are not currently up-to-date with the data available on DEA AWS. We are investigating the cause of this issue.
The affected services will be updated once the issue is resolved.
2 Sep 2024: Expanded extents data processing is currently paused, with data available to May 2024
This year, we expanded the processing extents for our Surface Reflectance products and derivative products.
Unfortunately, due to unanticipated issues with an external network connection, we have needed to pause the back-processing of this expanded extent data since May 2024. You may have noticed this issue, for example, if you attempted to access ARD from the Heard Island and McDonald Islands and found that there are no images more recent than May 2024.
