Rendering map is slower with leaflet then ajaxmaps

Post by broadhorizon »

This year we made the step of using Leaflet instead of ajaxmaps.

All is working is fine but we notice that when are zooming out in the map, we see a lot of gray parts.

We are using xServer version 1.32 on premise.

I'm using the code below to initialize the map:

Code: Select all

  var baseProfile = 'ajax';
  var xMapWmsUrl = 'http://localhost:50010/WMS/WMS';
  var xMapTileUrl = 'http://localhost:50010/WMS/GetTile/{profile}/{x}/{y}/{z}.png';

  var xMapAttribution = '<a href="http://www.ptvgroup.com">PTV<\/a>, HERE';

  map = new L.Map('mapDiv', {
                center: new L.LatLng(lat, lon),
                zoom: zoom,
                crs: L.CRS.PTVMercator
            });


  var bgLayer = L.tileLayer(xMapTileUrl, {
                maxZoom: 19,
                minZoom: 0,
                opacity: 1.0,
                noWrap: false,
                profile: 'xmap-' + baseProfile + 'bg',
                attribution: xMapAttribution
            }).addTo(map);

  var fgLayer = L.tileLayer(xMapTileUrl, {
                maxZoom: 19,
                minZoom: 0,
                opacity: 1.0,
                noWrap: false,
                transparent: true,
                profile: 'xmap-' + baseProfile + 'fg',
                attribution: xMapAttribution
            }).addTo(map);

What can I do to increase the performance of the rendering? So less gray parts are shown.

Hello Lanzo,

my first question regarding this topic: how many backend mapping modules are in use?
Are you aware of this post: https://xserver.ptvgroup.com/forum/view ... f=15&t=972
