Joining Pointwise Geological Data to Interpolation Grids if the Data Search Area is a Circle

Abstract – Pointwise geological data in are used as initial information for creating hydrogeological models (HM). Interpolation methods are applied to create -maps on (xy)grids of HM. The maps represent geometrical and physical features of geological layers. If solutions of boundary field problems are used as interpolation results then in represent boundary conditions. They must be joined to nodes of the interpolation grid. In this paper the case is considered when the local data search region presents a circle. Features of this approach are investigated if the circle radius changes from zero to two plane steps of a uniform (xy)grid
