  • InSAR digital terrain models for mining areas based on Sentinel-1 imagery. A case study in Căliman area

    Author: Mihaela GHEORGHE, Andrei-Ioan VODĂ MARC

    Abstract: Although not intended at first, SAR satellite technology has been used for digital terrain
    models (DTM) generation and displacement monitoring for the last 30 years starting with the launch
    of the first RADAR imaging satellite by the European Spatial Agency (ESA), ERS-1. Currently, there
    is a suite of satellites available for these applications, with ESA’s Sentinel-1 being one of the most
    accessible and exploited by scientists due to its wide and free of costs availability. The C-band repeatpass
    interferometer is considered unsuitable for DTM generation due to its acquisition geometry. In
    this study, a DTM based on Sentinel-1 imagery for the former sulphur quarry mine in Căliman
    Mountains is derived in order to demonstrate the potential of the dataset for time and cost effective
    monitoring of large areas.
