如何调用python地图

如何调用Python地图

Python中调用地图通常指的是使用地图相关的库来进行地理数据的可视化，Python有多个库可以用来处理地图和地理数据，如Folium、Geopandas、Mapbox等。

Folium

Folium是一个Python库，用于创建和处理Leaflet地图，它可以轻松地将数据可视化到交互式的Leaflet地图上。

示例代码：

import folium
创建地图对象
m = folium.Map(location=[35.6895, 139.6917], zoom_start=10)
添加标记
folium.Marker(location=[35.6895, 139.6917], popup='Tokyo').add_to(m)
保存地图到html文件
m.save("map.html")

Geopandas

Geopandas是一个开源项目，它使得在Python中更容易处理地理空间数据，它扩展了Pandas库，允许你在DataFrame中使用地理数据。

示例代码：

import geopandas as gpd
import matplotlib.pyplot as plt
读取shapefile或其他格式的地理数据
world = gpd.read_file(gpd.datasets.get_path('naturalearth_lowres'))
筛选数据
cities = world[(world.pop_est > 0) & (world.continent == "Asia")]
画图
cities.plot()
添加标题
plt.title('Asian Countries')
显示地图
plt.show()

Mapbox

Mapbox是一个提供交互式地图服务的公司，他们的API允许开发者在应用程序和网站上嵌入地图，使用Mapbox，你可以在Python中创建和使用地图。

示例代码（需要注册Mapbox账户和获取access token）：

import mapbox as mbx
from mapbox import TileLayer, FeatureGroup, Popup, LineString, Polygon, Circle, Color, Fill, Stroke, CircleMarker, MapboxStaticTileProvider, MapboxVectorTileProvider, MapboxGeoJSONTileProvider, MapboxMapProvider, MapboxGeoJSONFeatureCollection, MapboxMapOptions, MapboxMap, MapboxEventsAdapter, MapboxMapOptionsBuilder, MapboxMapBuilder, MapboxMapComponentAdapter, MapboxMapComponentBuilder, MapboxMapComponentOptionsBuilder, MapboxMapComponentOptions, MapboxMapComponentAdapterBuilder, MapboxMapComponentBuilderBuilder, FeatureManager, StyleManager, TileManager, VectorTileManager, GeoJSONTileManager, MapboxMapComponentAdapterBuilderBuilder, MapboxMapComponentOptionsBuilderBuilder, MapboxMapOptionsBuilderBuilder, MapboxMapBuilderBuilder, MapboxMapComponentAdapterBuilderBuilderBuilder, MapboxMapComponentOptionsBuilderBuilderBuilder, MapboxMapOptionsBuilderBuilderBuilder, MapboxMapBuilderBuilderBuilder, MapboxMapComponentAdapterBuilderBuilderBuilderBuilder, MapboxMapComponentOptionsBuilderBuilderBuilderBuilder, MapboxMapOptionsBuilderBuilderBuilderBuilder, MapboxMapBuilderBuilderBuilderBuilder, MapboxMapComponentAdapterBuilderBuilderBuilderBuilderBuilder, MapboxMapComponentOptionsBuilderBuilderBuilderBuilderBuilder, MapboxMapOptionsBuilderBuilderBuilderBuilderBuilder, MapboxMapBuilderBuilderBuilderBuilderBuilder'
