摘要: 数据网格化是图形绘制、科学计算和空间模型实现的基础工作。文章提出了空间数据从行政单元向网格单元转化的技术方法,在ARC/INFO软件的支持下,以人口数据为例,实现了这一方法。结果表明:利用网格单元表达社会、经济数据的空间分布,比用行政单元本身更接近于实际。如果提高网格单元的分辨率和行政单元数据的空间尺度,网格化的结果就会达到更加令人满意的效果。而且这种方法也可以用于其它统计单元数据(包括遥感数据)向网格单元的转化。

Abstract: Data gridding is a fundamental work to plot map, calculate for science and realize the spatial model. In this paper, a new method of spatial data transform from administration cell to gridding cell is presented and realized with a case of population data, supporting with ARC/INFO software. As a result, the spatial distribution of social and economic data what gridding cells express is closer to fact than what administration cells do. With the spatial resolution of gridding cells improved and the spatial scale of administration cell increased, this method of data gridding will have a more satisfied effect. Furthermore, it can be applied for data gridding from other statistics cell including remote sensing data to gridding cell.
