标准摘要
[中文适用范围]： 本文件规定了网格方格统计的基本原则，并包括以下内容：——定义或规定一套可推荐作为标准方法的统计方法，以便基于不同国家和地区使用不同地理编码系统和不同几何形状的网格方格参考系统所产生的网格统计结果，达成普遍共识，从而支持政策决策。——标准化方法，以实现不同几何形状的网格方格参考系统之间网格统计数据的转换计算，通过基于网格面积的按比例分配方法，以及计算近似误差的方法，以交换转换后的网格统计数据。除了网格方格外，还存在其他空间表达方式，但本文件不适用于这些其他空间表达方式。注：第4条和第5条定义了网格方格统计，并规定了一些生成网格方格统计的方法。第6条推荐了基于不同网格方格参考系统生成的网格方格统计之间的转换方法。 [外文原描述]： This document specifies a fundamental principle on grid square statistics and includes the following: — To define or specify a set of methods that can be recommended as the standard method to enable policy decisions based on common recognition from grid statistics produced with different grid square reference system standards in different countries and areas that can have different geographic coding systems with different geometric shapes. — To standardize methods to accommodate the conversion calculation among grid statistics with different grid square reference systems having different geometric shapes by employing prorating method based on the grid areas as well as the method to calculate the approximation errors, for exchanging the converted grid statistics. Spatial expressions other than grid square also exist, but this document does not apply to the spatial expressions other than grid square. NOTE Clause 4 and Clause 5 define grid square statistics and specify some methods to generate grid square statistics. Claus e 6 recommends conversion methods between grid square statistics generated based on different grid square reference systems.
