作者您好!

最近仔细阅读了您的论文,您提出的方法在学习spatio-temporal方面有非常多值得学习的地方。在阅读您的代码的过程中遇到了一些疑惑的地方想向您请教。

  1. 代码中有altitude.npy文件用于存储中国范围各像素点的海拔高度信息,想请问这个npy文件是如何获得/生成的?因为中国的经度最右能到131左右,维度最高能到50左右,但是文章中比这个范围小,我应该如何能够拓展范围?

  2. 如果我的理解没有错的话,代码中有经纬度向xy坐标转化的步骤,若is_altit=True可以正确获得altitude.npy中的值。但是这个放缩和转换是如何实现的?我没能很好地理解这个步骤。以及若is_altit=False会发生什么?

  3. is_altit=True/False分别对应了两套不同的lon、lat、res值,请问这些值为什么需要设置不同?

辛苦作者抽时间解答疑惑!
