如何在 Python 中通过 GeoDataFrame 绘制自定义国家地图

Question

我有一个关于通过 Python 中的 GeoDataFrame 绘制我的国家的问题。

完成基本过程后，我得到了一个在我的国家/地区显示的数据框。

代码段引发有关数据帧大小的错误。

我该如何解决它？

这是我的数据帧

index   Longitude   Latitude    geometry
0   0   27.000  41.000  POINT (27.00000 41.00000)
1   1   27.400  37.800  POINT (27.40000 37.80000)
2   2   27.300  37.850  POINT (27.30000 37.85000)
3   3   28.900  40.500  POINT (28.90000 40.50000)
4   4   36.100  36.100  POINT (36.10000 36.10000)
... ... ... ... ...
317 317 27.414  36.929  POINT (27.41400 36.92900)
318 318 38.514  37.596  POINT (38.51400 37.59600)
319 319 29.697  37.948  POINT (29.69700 37.94800)
320 320 28.173  40.890  POINT (28.17300 40.89000)
321 321 39.081  38.390  POINT (39.08100 38.39000)

这是我的代码片段

df_point_TURKEY = df_point[df_point["Country"] == "TURKEY"]
df_point_TURKEY = df_point_TURKEY.drop("Country", axis=1)
df_point_TURKEY.reset_index(drop=True, inplace=True)
df_point_TURKEY["index"] = np.arange(0,len(df_point_TURKEY))
geometry = [Point(xy) for xy in zip(df_point_TURKEY['Longitude'], df_point_TURKEY['Latitude'])]
gdf = GeoDataFrame(df_point, geometry=geometry)   
#this is a simple map that goes with geopandas
world = gpd.read_file(gpd.datasets.get_path('naturalearth_lowres'))
gdf.plot(ax=world[world["name"] == "Turkey"].plot(figsize=(16, 8)), 
marker='o', 
color='red', 
markersize=15
);
plt.title('Earthquakes occurred from 2100 BC in Turkey',fontsize = 25)
plt.savefig('images/image12.png')
plt.show()

错误：ValueError: Length of values does not match length of index

Answer 1

我忘了更改代码

取代

gdf = GeoDataFrame(df_point, geometry=geometry)   

跟

gdf = GeoDataFrame(df_point_TURKEY, geometry=geometry)
