Comparative Analysis of Methods to Estimate Geodetic Strain Rates from GNSS Data in Italy
收藏资源简介:
This dataset comprises GNSS velocity field and strain rate maps for Italy. List of Files: velocity_dataset.dat GNSS velocity field of stations with time series longer than 4.5 years. Columns: Longitude (degrees), Latitude (degrees), East component of velocity (mm/yr), North component of velocity (mm/yr), Uncertainty on the East component (mm/yr), Uncertainty on the North component (mm/yr), Station Name. velocity_dataset_filtr.dat Filtered velocity field. Columns: Longitude (degrees), Latitude (degrees), East component of velocity (mm/yr), North component of velocity (mm/yr), Uncertainty on the East component (mm/yr), Uncertainty on the North component (mm/yr), Station Name. Stations ending with 'GPM' represent velocity values obtained by merging neighboring stations. strain_rate_nn.dat (strain_rate_visr.dat, strain_rate_wav.dat) Strain rate computed on cells spaced by 0.025°. Suffixes in the file names: 'nn' refers to the Nearest Neighbor method, 'visr' refers to the VISR method, and 'wav' refers to the Wavelet-based method Columns: Longitude (degrees), Latitude (degrees), exx (east) component of the strain rate tensor (nstr/yr), exy (east, north) component of the strain rate tensor (nstr/yr), eyy (north) component of the strain rate tensor, second invariant of the strain rate (nstr/yr), most extensive eigenvalue (nstr/yr), most compressive eigenvalue (nstr/yr), angle between north and the direction of the eigenvector corresponding to the most compressive eigenvalue (degrees, positive clockwise).
