DEA Tech Alerts and Changelog
Find out about the latest updates to Digital Earth Australia’s products and services, planned maintenance, and any outages that may occur.
DEA System Status
All DEA systems are working as expected. There are no outstanding incidents or errors to report.
See the DEA monitoring dashboard to check the current status of DEA’s services.
2024-04-23: It’s now easier to cite DEA products
A new ‘Cite this product’ section has been added to each product page to make it easier to cite the product in your academic paper, article, or presentation. A citation may been provided for the data itself, and where relevant, to the published methods paper.
See this feature on the DEA Waterbodies product page.
2024-04-18: New Validation reports section
The Knowledge Hub contains a new Validation reports section. This is where you will find reports of Geoscience Australia’s validation data, published periodically. This data can be used to validate Geoscience Australia’s other datasets.
See the latest Daily Validation Summary Report: 2023-11-27: Transect NSW Site 1, Sentinel-2B overpass
2024-04-10: DEA Intertidal 1.0.0 released
The DEA Intertidal product suite maps the changing elevation, exposure and tidal characteristics of Australia’s exposed intertidal zone, the complex zone that defines the interface between land and sea.
This new product suite expands upon the DEA Intertidal Elevation (Landsat) product which has now been deprecated.
See DEA Intertidal for more information.
2024-04-03: Terra-derived DEA Hotspots have been restored
Direct Broadcast satellite downloads from the Terra satellite have been restored and have been successfully processed into DEA Hotspots.
2024-03-28: DEA Sandbox outage (Resolved)
Users may have encountered an unplanned outage on the Digital Earth Australia Sandbox.
DEA has implemented a solution as we continue to investigate the cause of the problem.
DEA Sandbox users are warned to expect intermittent issues over the next 12 hours.
Users may be unable to log in to or access their DEA Sandbox account while the incident is being investigated. Users may also notice reduced performance on other DEA systems during this outage.
You can monitor the status of DEA’s systems on the DEA monitoring dashboard. If you would like to contact DEA, please email earth.observation@ga.gov.au
2024-03-25: DEA Waterbodies version 3.0.0 released
Improvements include additional supporting data for the most recent observations made available through web mapping services (WMS) and DEA Maps, more metadata, Landsat 9 data, and pipeline upgrades. Version 3.0.0 of DEA Waterbodies uses the same underlying polygon set as DEA Waterbodies version 2.0.0. Learn more
2024-03-21: DEA OWS services restored
Outages affecting DEA Open Web Services (OWS) have been resolved. Work will be continuing over the coming months to further improve performance and reliability of these services.
See the DEA monitoring dashboard to check the current status of DEA’s services.
2024-02-26: Sentinel-2 contiguity fix reprocessing complete
Learn more in the Sentinel-2A Surface Reflectance NBART and Sentinel-2B Surface Reflectance NBART changelogs.
2024-02-20: DEA Notebooks update
A minor update to the DEA Tools package that includes updates to tide modelling and parallel processing functions. It also adds a new load_reproject function to the datahandling module which allows reading and reprojecting external raster data. For more detail, see the dea-notebooks 0.3.1 release notes.
2024-02-20: New external land use and bathymetry datasets added to DEA Sandbox
Two new external datasets have been added to the DEA Sandbox: the 2020 ABARES Catchment Scale Land Use of Australia 50m dataset, and the recently released 2023 Geoscience Australia AusBathyTopo 250m high-resolution depth model for Australia. These datasets provide valuable insights into land use patterns and the physical shape of Australia’s mainland, our coasts and deep ocean regions.
These datasets can be loaded on the DEA Sandbox using the product names abares_clum_2020 and ga_ausbathytopo250m_2023.
2024-02-15: Upcoming changes to DEA Geomedian, Median Absolute Deviation and other derivative products
The Geoscience Australia Landsat Geometric Median and Median Absolute Deviation Collection 3 products v3.1.0 are undergoing a major upgrade which will be released shortly as v4.0.0.
Find out the details here.
2024-01-24: Water Observations and Fractional Cover Percentiles 2023 annual summaries released
See DEA Water Observations Statistics (Landsat) and DEA Fractional Cover Percentiles (Landsat) for more information.
2024-01-10: Sentinel-2 contiguity fix - Reprocessing commenced
Reprocessing to fix the Sentinel-2 contiguity issue has commenced with expected completion in early 2024. The issue was caused by anomalies in ESA Level 1 source data.
A known Sentinel-2 contiguity issue created by ESA Level 1 anomalies (“Striping due to lost source packets”) is impacting approximately 0.5% of our Sentinel-2 Analysis Ready Data (S2 ARD) between 2015 and 2023.
Affected products:
ARD Sentinel-2 products (ga_s2am_ard_3, ga_s2bm_ard_3)
