| Abstract: | The data gridding techniques can be divided into three types: traverse type data gridding, contour type data gridding and discrete point type data gridding. The gridding technique for contour type data block storage and mesh points eight directional searching interpolation discussed in this paper can quite satisfactorily solve the gridding calculation problem for planar contour type digitalized data. The technique is characterized by large quantities of calculated data, good feasibility, high precision and rapid calculation speed. |
