Geoscience Australia has released the latest version its DynAdjust least squares adjustment software tool.
Version 1.4 is said to be faster, more efficient and better aligned with modern geodetic workflows.
DynAdjust is used to calculate highly accurate co-ordinates from survey and GNSS data, and can be and has been used for:
- Small survey control networks;
- Engineering surveys;
- Deformation monitoring surveys;
- National and state geodetic networks; and
- Digital cadastral database upgrade initiatives.
According to the software’s GitHub page, the software “has been designed to estimate 3D station coordinates and uncertainties for both small and extremely large geodetic networks, and can be used for the adjustment of a large array of Global Navigation Satellite System (GNSS) and conventional terrestrial survey measurement types”.
“On account of the phased adjustment approach used by DynAdjust, the maximum network size which can be adjusted is effectively unlimited, other than by the limitations imposed by a computer’s processor, physical memory and operating system memory model.”
Better, faster, future-focused
The version 1.4 upgrade brings with it:
- Speedier performance: Processing speeds were found to be around 1.5 times faster during testing, which should enable users to get through large datasets more efficiently.
- Lower memory use: Large adjustments can be run on more modest computing resources.
- Clearer and more consistent outputs that help users better understand processing and adjustment performance.
- Improved interoperability: New JSONL support makes it easier to connect with modern data workflows and automated processing.
- Future-ready updates: Foundational support is provided for additional reference frames and observation epochs.
DynAdjust is widely used by agencies across Australian state and territory governments, as well as the federal government, and has also been employed internationally.
