Abstract

In this paper considers the development of a project module "Mobile GIS", providing the possibility of building surfaces and contours on the basis of a set of information about the altitude in certain points. The variants of the acceleration of the operation of the double interpolation algorithm for the processing of heterogeneously distributed data are considered. The application of various interpolation functions of two variables is considered and the quality of recovery of the result is analyzed.
