When working with signal processing, I use zeros to pad signals: # Original signal signal = np.array([1, 2, 3, 4, 5]) # Pad with zeros (zero padding is common in signal processing) padded_signal = np.zeros(10) padded_signal[:len(signal)] = signal ...
省去了寻找shape文件的麻烦2.使用maskout.py这个模块,其中的函数shp2clip_new(originfig, ax, shpfile, clabel=None,vcplot=None)可帮助我们绘制想要的shape3.salem库,这个方法比较简单,通过.salem.roi(shape= )这个方法可以更具shape文件来筛选数据4.polygon_to_mask,可生成掩膜数组,为布尔值,可根据该布尔数组...
