Computation of a precise local gravimetric geoid model with sparse and limited data is a difficult task. This research investigates the procedure for gathering evaluating data and combining them with grid data in order to determinate an optimum gravimetric geoid model. We compiled a new geoid model at the computation area of Latvia using the method developed at the Royal Institute of Technology (KTH) in Stockholm. This method utilizes the least-squares modification of the Stokes integral for the biased, unbiased, and optimum stochastic solutions. The modified Bruns-Stokes integral combines the regional terrestrial gravity data with a global geopotential model (GGM).
