Ground Displacements

To record the data, we use a simple format of the form:

    Line 1: header information
    Line 2-Ns: site X(km) Y(km) UX(m) UY(m) UZ(m) dUX dUY dUZ
    

where site is the “station name” (like I14), Ns is total number of sites, X and Y are the station coordinates, UX, UY, UZ are the permanent ground displacements in X, Y, (in m) and the vertical direction, and dUX, dUY, dUZ are their corresponding uncertainties.

Following is an example of a .dsp file. Please note .dsp extenstion is not mandatory - you can use '.dat' but '.dsp' is used on the site.

    %   Name X(km)  Y(km)   UX(m)  UY(m) UZ(m) dUX(m) dUY(m) dUZ(m)
