python和百度地图API实现数据地图标注
先上效果图：
在上海地区测试了下批量经纬度在百度地图上的标注
先用python进行数据处理
data_html = pd.DataFrame(columns=['content'])
for indexs in group.index:
data_html.loc[indexs,'content'] = '{' + \
'"lat":' + str(group.loc[indexs,'lat']) + ',' + \
'"lng":' + str(group.loc[indexs,'lon']) + ',' + \
'"quyu":' + '"' + str(group.loc[indexs,'cluster']) +'"' + \
'}' + ','
data_html.to_csv ("data_html.csv",encoding="gbk",index=False)
data_html
类似于如下格式：
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css">
body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;font-family:"微软雅黑";}
</style> <script type="text/javascript"
//ak填自己申请的ak
src="http://api.map.baidu.com/api?v=2.0& ak=3CNzed0LQ2W5PW2l0MQb9OFhfSjj9AfB">
</script> <title>百度地图api展示</title> </head> <body> <div id="allmap"></div> </body> </html> <script type="text/javascript">
