Gridding and contouring with inverse distance weight method

The general purpose of the contouring method that used in many areas is to make the data understandable by showing the data concentration from obtained data in scientific studies. In this study, a software has been developed to show raw data gathered from any field of studied area with contouring method after pre-processed. During the pre-processing of XYZ raw data, at first, a grid called a coordinate network or a data plane network has been created. The inverse distance weight method was used in the gridding process. Gridding is completed by assigning an XYZ data for each node of the grid area. After the pre-processing the data and the gridding, contour maps of the collected data were obtained by contouring of the generated grid. The results obtained with the proposed method were compared with the results obtained from Surfer software. At the end of the comparison, the same values and contour graphs were obtained. Considering the comparison results, it is thought that it can be used as an alternative to commercial products.
