Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO)
The occasion was on CALIPSO's 9,491st orbit of Earth. Since its launch, on April 23, 2006, the satellite has traveled 260,198,685.3 miles. It has generated data that would fill almost 3,500 DVDs or more than 24,000 CDs, delighting scientists and researchers from 35 countries who are using the information to prove any number of theories about the atmosphere, about weather, about the past and how it will relate to the future.

GDAL C#封装还是没有解决中文字符的问题。C# 采用Unicode,GDAL的Dll采用多字节字符。所以只能在C++的代码中做些工作,将Unicode转换为多字节字符或者是Utf8。准备测试一下。
