I want to do something similar to this example: http://jsfiddle.net/3v7hd2vx/36/

But instead of creating a polyline between the two points, I want to display already digitalised routes all stored in a GeoJSON file between each point.

Is this possible?

Here is what the lines GeoJSON looks like:

yes that easy. for example

var paths = [geojsonArray];

var timeAnimation = 1500;
var next = 0;
var nextpnt = 0;

setInterval(function(){
  if(next<paths.length){
    var path = paths[next];
    nextpnt=0;
    var coords = path.geometry.coordinates;
    var littleTime =  parseInt(timeAnimation/coords.length);
    setInterval(function(){
     // split to coordinate array for every loop and setCoordinate polyline geometry
    nextpnt++;
    },littleTime);
  }else{
    //remove interval
  }
},timeAnimation )

  • Thanks, seems correct but somehow can't apply it to my data. I edited my question to show the two GeoJSONs I'm working with.
