[2] 矢量（中国、北京五环路、Download free geographic (GIS) data for any country in the world）.

[3] 海量数据（两个矩阵）依据单一字段关联属性。此时，万万不可逐条循环匹配，时间过久。参考思路如下：

1 2 3 4

% A & B have two or more fields, maybe they both are cell matrices, using the funtion 'intersect' % n or m means some numerical, such as 2, 3, etc. [C, ia, ib]=intersect(A(:, n), B(:, m))); otmat=[A(ia, :), B(ib, 2)];

[4] SQL Language.

[5] 原始下载文件转换为可正常读写的文件，并将这些分块导出的文件归纳为单一文件。注意尽量减少原始下载文件的字段，避免意外的异常.Vrsn2.0.Vrsn3.0.Vrsn4.0. Vrsn5.0.Vrsn6.0.

[6] 时间序列文件归一，输出时间序列数据列表，第一列是匹配字段.第二版.

[7] INDEX List.
