Abstract Firstly, in the least square collocation, we get the preferable regional velocity field based on WGS-84 ellipsoid from the polynomial function, the Gaussian function, the homo-Gaussian function, the Hirvonen function, the space harmonic functions (two), and six different kinds of covariance function. Then, through the better method, we get the GPS strain field of the study area by using rotation in the entire block and homogeneous strain model (REHSM). Eventually, we analyzed the 19 GPS sites based on the “digital seismic network project’s” 2007-2010 GPS monitoring data in the Yuncheng basin.
