Geofem applies state of the art technologies and analysis of satellite radar data (InSAR) using specialised software (SARMAP SARScape) to measure ground movements due to mining activities.
Our combination of geotechnical and satellite radar expertise provides optimal solutions for our clients. We measure ground and structural movement and estimate the affected areas caused by mining activities.
Douglas Park New South Wales, Australia
Geofem conducted a Synthetic Aperture Radar (SAR) Interferometric survey for the greater area surrounding Douglas Park for ground stability monitoring purposes during mining activity. Ground displacement was identified (areas in red) coinciding with the mining operations. Ground displacement estimates from satellite radar analyses were in agreement with in situ surveying data.
Illawarra Coal Mining
Geofem performed an SBAS analysis using a dataset of Sentinel-1 SLC images for the period between December 2016 and July 2018. Results showed the distribution of displacements and the extent of area affected.
