MultiDEFusion: an open-source library dedicated for the integration of geodetic observations

07-05-2024

MultiDEFusion is an open-source library that enables the Fusion of Multi geodetic techniques ensuring long-term observations of ground DEFormation. The software, developed in a Python environment, enables the integration of permanent GNSS observations together with InSAR radar data.



The MultiDEFusion library expands the existing approach of integrating geodetic observations introduced in the article Tondaś et al., 2023, by allowing the simultaneous application of three InSAR computational methods: DInSAR, SBAS, and PSI. Furthermore, radar observations can be derived from three independent orbits with the possibility of implementing 9 elements (pixels or PS points) for each computational method.

The core of the MultiDEFusion library relies on the Kalman filter algorithm, which produces a time series of calculated parameters. Additionally, it provides an interactive graph feature, enabling users to perform a detailed evaluation of the obtained results. The library can be installed in the Python environment using the „pip install multidefusion” command.

Detailed software documentation, including references to the trial data set, is available at https://damiantondas.github.io/multidefusion. Future work on library functionality will focus on extending the algorithm's capabilities to include additional methods for geodetic monitoring of ground movements, such as levelling or GNSS campaign measurements.
