Special Issue Information

Dear Colleagues,

The exploitation of Synthetic Aperture Radar (SAR) imaging is rising higher and higher on the agenda of researchers, professionals and stakeholders working in the field of geomatics, geodesy, surveying, Earth sciences, land management and monitoring.

Through their all-weather and day/night sensing capabilities, range of frequency bands, manifold spatial and temporal resolutions, like and cross polarizations, and looking modes and beams, SAR data can provide key geoinformation for a number of geoscience applications.

This Special Issue of Geomatics aims to gather research articles, reviews and short communications on all aspects of SAR for geosciences, including (but not limited to):

  • Sensor design, data calibration and validation, technology and platform development, including novel ground-based, UAV/drone and airborne setups, as well as spaceborne systems
  • Signal processing and advanced techniques for image analysis and enhancement, machine learning, deep learning and artificial intelligence, big data analytics, classification, segmentation, target detection and monitoring, data fusion, tomography, polarimetry
  • Cartography, surveying, geomorphological mapping, digital surface modeling through radargrammetry and Interferometric SAR (InSAR)
  • Land and environmental monitoring through change detection, offset tracking, Differential InSAR (DInSAR) and multi-interferogram approaches based on coherent, persistent and distributed scatterers (e.g., PS, SBAS, MT-InSAR, SqueeSAR), Multiple-Aperture Interferometry (MAI)
  • SAR applications for biophysical and geophysical parameters retrieval, meteorological applications, natural and anthropogenic hazards and risk mapping, urban and structural health monitoring, oceanography and maritime applications

Persistent Scatterer Interferometry (PSI) techniques are now well established and accepted for monitoring ground displacements. The presence of shallow-seated landslides, ubiquitous phenomena in the tropics, offers an opportunity to monitor and map these hazards using PSI at the regional scale. Thus, the Western Ghats of India, experiencing a tropical climate and in a topographically complex region of the world, provides an ideal study site to test the efficacy of landslide detection with PSI. The biggest challenge in using the PSI technique in tropical regions is the additional noise in data due to vegetation. In this study, we filtered these noises by utilizing the 95-percentile of the highest coherence data, which also reduced the redundancy of the PSI points. The study examined 12 landslides that occurred within one of the three temporal categories grouped as Group 1, Group 2, and Group 3, categorized in relation to PSI monitoring periods, which was also further classified into east- and west-facing landslides. The Synthetic Aperture Radar (SAR) data is in descending mode, and, therefore, the east-facing landslides are characterized by positive deformation velocity values, whereas the west-facing landslides have negative deformation values. Further, the landslide-prone areas, delineated using the conventional factor of safety (FS), were refined and mapped using PSI velocity values. The combination of PSI with the conventional FS approach helped to identify exclusive zones prone to landslides. The main aim of such an attempt is to identify critical areas in the unstable category in the map prepared using FS and prioritizing the mitigation measures, and to develop a road map for any developmental activities. The approach also helps to increase confidence in the susceptibility mapping and reduce false alarms. Full article
