Purpose.Investigation to study quasigeoid computations based on the regional gravimetric data and different types of nonorthogonal basis functions was assessed to be important.When measurements from only restricted regions of the Earth surface are available, global spherical harmonics loose their orthogonality in a limited region, so the determination of the coefficients of the model, usually by using the least squares method, is numerically unstable.In spite of this fact, there is a specific solution for Laplace equation for the situation of a spherical cap when the boundary conditions are appropriate.Methods.Our solution uses the gravity anomalies in the Arctic area taken from the Arctic Gravity Project (AGP).The method applied on this data set is adjusted spherical harmonic analysis (ASHA).Computation of the quasigeoid heights was performed by the "Remove -Restore" procedure in three steps.On the first step the free air gravity anomalies of the EGM 2008 model up to degree/order 360 were substracted from the initial gravity anomalies of the AGP to get rid of the low frequency gravity field content.On the second step the approximation of the residual gravity anomalies was based on the ASHA method.The construction of the normal equations matrix may lead to the time consuming procedure.For this reason the discrete orthogonality property in longitude for the chosen basis system was taken into account and led to the significant decrease of the computational time of the residual coefficients , kmkm ab.On the last step the residual quasigeoid heights (high frequency components of the gravity field) were computed via the residual harmonic coefficients , kmkm ab and added to the global contribution of quasigeoid heights taken from the EGM2008 model up to degree/order 360 (low frequency components of the gravity field).Results.Hence the gravity field model was constructed and compared with AGP gravity anomalies.Also the obtained model of quasigeoid heights was compared with quasigeoid heights from 49 GNSS/leveling points.Scientific novelty and practical significance.In this paper the modification of ASHA method was developed, which makes it possible to significantly accelerate the process of computing the unknown coefficients in the construction of local gravitational fields.This allows to compute local gravitational fields of higher orders.It is well known that quasigeoid accuracy depends on the order of model.

The work purpose – on the basis of 3d-model of a relief in GIS to sort out orographic lineaments of the upland Opillya (Ukraine). A method. For construction 3d-models of a relief (scale 1:200 000) on terrain Opillya the data of American mission SRTM has been used. For construction of 3d-models (scale 1:50 000) have executed numbering of horizontals of a topographic map.
