python - 有木有轻量级的地图框架或者库? GIS感觉强大了点.

Question

例如我有一些数据,表示某些地区的用户量.现在想找个地图,在相应的位置画一些柱状图,或者标记一些颜色,有什么好的工具或者库么?最好是python或java的

或者结合房间的定位信息(uwb或rfid之类的),然后在一个局部地图中显示实时位置,这该怎么做呢?

Answer 1

You can consider js libraries, such as openlayers and polymaps. This should be the most lightweight GIS library.

Answer 2

Just keep your feet on the ground... You need to use the map that others have already made, and then call the related functions of the map through the API provided by it... Google Baidu Aliyun can be used...
As for your first question... This is how I walked... You can use the cube map api of Alibaba Cloud Maps...
As for your second question... what I understand is that you want to do real-time positioning? In fact, you need to implement a comet... let the server transmit the real-time latitude and longitude to the front-end... and then the front-end calls the map api to show the effect of real-time positioning...

D3 library is the most widely used js data visualization library. Tutorials and demos are also quite abundant. And the open source is on github, and you can use it with a browser (chrome, firefox).
