I am working with leaflet. I am wondering, if it is possible to animate points on the leaflet map like cartoDB is doing it with torque.js. I basically need a timeslider for manual display and a play-button for automatic display of the data. I cannot use torque.js because my data depends on the user input and may change during a session various times. Uploading it to cartoDB is therefore no option. I am aware that there is the possibility to create torque-tiles from a postGIS database. But: loading the data which the user requests into a postGIS database, running the .py from cartoDB to create torque-tiles on it and then feeding it to the torque framework sounds hacky.

I am further interested in applying the solution - if possible - to polygons. I need to change a choropleth map over time.

You could try using d3js.

This example seems to match what you want : http://stat4701-edav-d3.github.io/viz/cities/cities.html

  • Yes, I am working with d3.js. Is there the commented code somewhere? It looks like what I need... – Stophface Feb 20 '17 at 12:59
  • The (non-commented..) code is available here : view-source:stat4701-edav-d3.github.io/viz/cities/js/main.js. I am working on an adaptation of this script and the code is not too hard to get in especially if you already work with d3js. You basically need to use and adapt the createSlider,() animate() and drawMonth() functions. – ConstanceL Feb 20 '17 at 13:08
  • Thanks. I found the sourcecode already. I thought there might be a commented version that I overlooked. I will have a look at it! – Stophface Feb 20 '17 at 13:35
