数据准备
我想往做好的地图上标注下所需的一些地点，而且之前我也已经整理好了对应地点的经纬度数据，并已经成功导入，数据结构长这样：
City Lon Lat
A *** ***
B *** ***
C *** ***
D *** ***
我之前尝试了用Basemap来插入这些点，但是一直在报错，我前面的地图已经做好，代码及地图如下：
import pandas as pd
import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.ticker as mpt
import matplotlib.colors as mcl
import cartopy.crs as ccrs
import cartopy.feature as cft
from cartopy.mpl.gridliner import LATITUDE_FORMATTER, LONGITUDE_FORMATTER
import cartopy.io.shapereader as shapereader
from cartopy.io.shapereader import natural_earth
proj = ccrs.PlateCarree(central_longitude=130) # 将地图中心移至我国
fig = plt.figure(figsize=(3,2),dpi=1200)
ax = fig.subplots(1, 1, subplot_kw={'projection': proj})
# 从文件中加载中国国界、省界和十段线数据，
with open(r'F:\Pycharm Project\First\Data\Data re-analysis\Map\Shapefiles\CN-border-La.dat') as src:
context = ''.join([line for line in src if not line.startswith('#')])
blocks = [cnt for cnt in context.split('>') if len(cnt) > 0]
borders = [np.fromstring(block, dtype=float, sep=' ') for block in blocks]
#从文件中加载中国区域shp
shpfile = shapereader.Reader(r'F:\Pycharm Project\First\Data\Data re-analysis\Map\Shapefiles\china_country.shp')
# 设置中国国土区域
shape_feature = cft.ShapelyFeature(shpfile.geometries(),
ccrs.PlateCarree())
ax.add_feature(shape_feature, color='w')
# 绘制边界及十段线
for line in borders:
ax.plot(line[0::2], line[1::2], '-', lw=0.3, color='k',transform=ccrs.Geodetic())
extent=[109,118,20,26] # 经纬度范围
ax.set_extent(extent)
gl = ax.gridlines(
crs=ccrs.PlateCarree(),
draw_labels=True,
linewidth=0.2,
color='k',
alpha=0.5,
linestyle='--'
)
gl.top_labels = False # 关闭顶端的经纬度标签
gl.right_labels = False # 关闭右侧的经纬度标签
gl.xformatter = LONGITUDE_FORMATTER # x轴设为经度的格式
gl.yformatter = LATITUDE_FORMATTER # y轴设为纬度的格式
gl.xlocator = mpt.FixedLocator(np.arange(110, 120 + 5, 1))
gl.ylocator = mpt.FixedLocator(np.arange(20, 30 + 5, 1))
gl.xlabel_style={'size':5}
gl.ylabel_style={'size':5}
ax.add_feature(cft.LAND.with_scale('10m'),color='w') # 添加陆地，颜色为白色
ax.add_feature(cft.RIVERS.with_scale('10m'),lw=0.5,color='royalblue') # 添加河流
ax.add_feature(cft.LAKES.with_scale('10m'),color='cornflowerblue') # 添加湖泊，颜色为蓝色
ax.add_feature(cft.OCEAN.with_scale('10m'),color='cornflowerblue') # 添加海洋
这是做出来的图片：
麻烦各位大佬指点一下下一步应该怎么按经纬度往上面标注点，我是想同时标出地点和对应的地点名
谢谢！
