我想这就是你想要的——在三维坐标轴上画出等距线。我已经在评论中解释了每个部分的作用import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
import itertools
#read in data from csv organised in columns labelled 'lat','lon','elevation'
data = np.recfromcsv('elevation-sample.csv', delimiter=',')
# create a 3d axis on a figure
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
# Find unique (i.e. constant) latitude points
id_list = np.unique(data['lat'])
# stride is how many lines to miss. set to 1 to get every line
# higher to miss more
stride = 5
# Extract each line from the dataset and plot it on the axes
for id in id_list[::stride]:
this_line_data = data[np.where(data['lat'] == id)]
lat,lon,ele = zip(*this_line_data)
ax.plot(lon,lat,ele, color='black')
# set the viewpoint so we're looking straight at the longitude (x) axis
ax.view_init(elev=45., azim=90)
ax.set_xlabel('Longitude')
ax.set_ylabel('Latitude')
ax.set_zlabel('Elevation')
ax.set_zlim([0,1500])
plt.show()
我用来测试的数据集不是我的，但我在github here上找到了它。在
输出如下：
注意-如果我误解了你草图中的坐标轴标签，你可以交换经纬度。在
