在地图上绘制图像

Question

我想在底图上的特定坐标处放置一幅小图像，我需要做哪些修改

def base_map(temp):
    fig = plt.figure(figsize=(360, 180), edgecolor='w')
    m = Basemap(projection='cyl', resolution='l',
                llcrnrlat=-90, urcrnrlat=90,
                llcrnrlon=-180, urcrnrlon=180, )
    draw_map(m)

    m.bluemarble()

    plt.show()

这是我想做的最终结果https://i.stack.imgur.com/XHLF6.jpg
