代码说明:

  该程序用于读取GTOPO30. GTOPO30 是一个全球的数字高程模型,它覆盖西经180度至东经180度,南纬90至北纬90度的所有区域。它的分辨率为30秒(即0.00833333度),生成 一个21,600(行)×43,200(列)的DEM。其高程值范围在-407至8752米。在数字高程模型中,海洋地区被指定为-9999 。 低地沿海一带,海拔至少有1米。(GTOPO30 is a digital elevation model for the world, developed by USGS. It has a 30-arc second resolution (approximately 1 km) and is split into 33 tiles stored in the USGS DEM file format.)
