python地理地图可视化:folium把百度地图各个城市经纬度解析出来并在地图上展示（三）

上一篇（https://zhangphil./article/details/110264421）把百度地图各个城市的经纬度解析出来了，现在通过folium把各个经纬度点在地图上绘制出来，代码如下：

import jsonimport webbrowser as wbimport foliumNAME = 'n'GEO = 'g'CITY = 'city'CITIES = 'cities'PROVINCE = 'province'PROVINCES = 'provinces'LAT = 'latitude'LNG = 'longitude'# 把百度地图文件装入字符串def load_origin_bd_file_to_str():f = open(file='BaiduMap_cityCenter.txt', mode='r', encoding='gbk')sss = f.read()f.close()return sssdef clean_data(sss):target = ('municipalities:', 'provinces:', 'cities:', 'n:', 'g:', 'other:')for old in target:news = '\"' + old.replace(':', '') + '\":'newsss = sss.replace(old, news)sss = newssssss = sss.replace(';', '')return sssdef get_city_lnglat(provin, cities):lnglats = []for c in cities:city_name = c[NAME]city_geo = c[GEO]lnglat = city_geo.split(',')lng = lnglat[0]lat = lnglat[1].split('|')[0]geo_dict = {}geo_dict.__setitem__(PROVINCE, provin)geo_dict.__setitem__(CITY, city_name)geo_dict.__setitem__(LNG, lng)geo_dict.__setitem__(LAT, lat)lnglats.append(geo_dict)return lnglats# 根据传入的各个城市经纬度绘制地图点def draw_map(city_lnglats):map = folium.Map(location=[35.3, 100.6],zoom_start=4,zoom_control=True,tiles='OpenStreetMap') # 默认OpenStreetMapfor city in city_lnglats:for c in city:folium.Marker(location=[c[LAT], c[LNG]],opacity=0.8,popup='<i>{0}\n{1}\n{2}\n{3}</i>'.format(c[CITY], c[LAT], c[LNG], c[PROVINCE]),icon=folium.Icon(color="red",# icon='cloud) # 默认的icon=info_sign,cloud样式也不错).add_to(map)map.save('map.html')wb.open('map.html') # 浏览器打开if __name__ == '__main__':origin_s = load_origin_bd_file_to_str()res = clean_data(origin_s)json_result = json.loads(res) # 到这里已经是标准的json格式数据provinces = json_result[PROVINCES]city_lnglats = []for pro in provinces:city_lnglats.append(get_city_lnglat(provin=pro[NAME], cities=pro[CITIES]))draw_map(city_lnglats)

最终输出，如图所示：
