| Abstract: | Interpolation procedure is broadly used in sciences that are concerned with spatial data and continuous phenomena that can be depicted on a spatial surface. Interpolation makes use of sampling data, which is accurate and qualitative, in order to produce a continuous representation of the phenomenon in question. The data's accuracy is transferred by the procedure to its results and should be known. This paper examines error propagation by the interpolation procedure, using the Inverse Distance Weighted (IDW) method in the case of the Earth's relief. |
