一种实用的等值线型数据网格化方法

摘要

数据网格化通常包括三大类：测线型数据网格化、等值线型数据网格化和离散点型数据网格化。文中研究的等值线型数据分块存储、网格点八方位搜索插值的网格化方法较好地解决了平面等值线型数字化数据的网格化计算问题，其计算数据量大，实用性强，精度高，计算速度快。%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.
