C#遥感数据头文件批量生成器

1、长时间序列中国NDVI数据GIMMS（下载地址：寒区旱区科学数据中心）,提供Albers投影的tif格式数据集。

2、长时间序列全球NDVI数据GIMMS 3g（下载地址：Ecocast），元数据无投影，格式为VI3g，IE浏览器下载的为.txt格式。GIS软件无法直接打开，Envi
5.1打开，参照：ENVI5.1中快速打开及处理GIMMS数据。

Envi5.1中打开二进制（Binary）数据是，需要提供头文件，考虑到该数据集的大小范围都一致，可以共用一个头文件，只需要将头文件的名称与数据文件一致，由于Python和IDL知识的欠缺，最终考虑使用C#批量生成，思想是：每读到一个数据文件，按名称生成一个头文件（.hdr）,而头文件的内容是在Envi5.1中打开第一个数据是生成的。
