Analysis of sinking incidence in the San Luis Potosí Valley, México Conference Paper uri icon

abstract

  • This research focused on the geospatial method application called Synthetic Aperture Radar Interferometry (InSAR) using Sentinel 1-A satellite images to determine the sinking incidence in the San Luis Potosí - Soledad de Graciano Sánchez conurbation area. In this study was carried out the processing and comparison of the sinking values resulting from the period 2014 to 2019, where the procedures showed that the sinking incidence that occurred in some areas of San Luis Potosí Valley was 13.4 cm, which means that a sinking of approximately 2.6 cm would be generated per year in the specific areas determined, as well as, with the results of the InSAR method was made a profiles graphic of the 5 years analyzed, with the aim of observing the behavior of soil sinking in the area studied. Likewise, 72 GNSS vertices were interpolated, which served to know the ground elevations in 2014, in order to correlate their differences according to the results of the interferometry process in the images using SNAP software. © Published under licence by IOP Publishing Ltd.
