Two of the leading players in the monitoring industry, Geopraevent and IDS GeoRadar, both Hexagon companies, have introduced SLYX Slow Movement Analysis, a solution that goes beyond standard analysis of tailing dams.

IDS GeoRadar launches SLYX for slow movement analysis on tailing dams

To reliably monitor slow movements over several months or even years is very challenging especially on fixed, but vegetated slopes such as tailing dams, where the smallest movement can be a precursor of a slope failure. SLYX measures very slow displacements with an unprecedented coherence in the resulting data.

The algorithm is based on an automatic selection of the most suitable measurements from the IBIS radar data and on a tailored evaluation for slow movements. This procedure gets even closer to the detection limits, accurately determining millimetre movements over extended time periods.

SLYX is integrated in IBIS Guardian with a dedicated interface for easier application. The analysis period and the measurement window for analysis are flexible and can be selected by each user.

“The reliable and accurate measurement of small, slow movements is difficult. With SLYX Slow Movement Analysis, we launch a powerful tool that allows us to do just that. The SLYX algorithms make it possible to detect large-scale mm movements over several days to months that would normally be lost in instrumental noise,” says Lorenz Meier, Geopraevent CEO.

Francesco Coppi, IDS GeoRadar director of Monitoring Radar Product Management, comments: “Slow movements play an important role as early precursors for potentially catastrophic slope failures, as it could happen for tailing dams. SLYX represents a game changer in this field.”
