Animated symbols on a map using Leaflet (open street map) and node.js
This project is under construction:
It uses Leaflet to handle map graphic layers and Stamen for the underlying map.
The data is provided via websockets using a node server
Temporary local files
internetsensors/mbtanode:
- tn.js (background node server: mbta api and websockets)
- leafredline1.html (handles leaflet code) and must be run on a web server.
After the map loads, scroll down and send the message “go” to open the websocket.
notes:
The animation of the train symbols is very primitive. It redraws the entire train line with each polling request.
There are better methods to move symbols on a leaflet map – to be used in subsequent versions.
