javascript - Best way to import coordinates from .gpx file and display using Google Maps API -


i mountain biker , track rides on samsung s3 galaxy using programs such endomondo , strava. regarding ride saved on these 2 websites.

i have own personal website display mountain routes in various areas stay. route data recorded via gps using endomondo , strava have exported .gpx file. need data in .gpx file display on own personal website. started solution using google maps api , importing .gpx file without using external tool.

i struggled find answer. came across post guy uses jquery extract data in xml file , display data on google map: http://www.jacquet80.eu/blog/post/2011/02/display-gpx-tracks-using-google-maps-api

this how implemented html markup:

<script>      function initialize() {           var route1latlng = new google.maps.latlng(-33.7610590,18.9616790);           var mapoptions = {                center: route1latlng,                zoom: 11,                maptypeid: google.maps.maptypeid.roadmap           };           var map = new google.maps.map(document.getelementbyid("map_canvas"), mapoptions);            $.ajax({                type: "get",                url: "gpx/my_route.gpx",                datatype: "xml",                success: function (xml) {                     var points = [];                     var bounds = new google.maps.latlngbounds();                     $(xml).find("trkpt").each(function () {                          var lat = $(this).attr("lat");                          var lon = $(this).attr("lon");                          var p = new google.maps.latlng(lat, lon);                          points.push(p);                          bounds.extend(p);                     });                     var poly = new google.maps.polyline({                          // use own style here                          path: points,                          strokecolor: "#ff00aa",                          strokeopacity: .7,                          strokeweight: 4                     });                     poly.setmap(map);                     // fit bounds track                     map.fitbounds(bounds);                }           });      }      google.maps.event.adddomlistener(window, 'load', initialize); </script>

it works. correct way it? there better way implement this?

if use postgresql database, i'd suggest use postgis , import records database. can generate kml files (st_askml) , display them on google map. if gpx huge, can use st_simplify on database query page loaded faster , still have full detailed route in database.

you have lot of possibilities:

  • search rides in specified area
  • measure total distance in month
  • and more
