GeographicMap - map tiles don't display when setting WorldRect
posted

I am using a geographic map with a static geotiff image that I converted to tiles.

If I don't specify the world rect, my map and symbol series both show, but my symbol series is in the wrong location. When I set the world rect to the parameters of my image, then the symbol series shows accurately but the map does not appear at all.

It seems to be a similar problem to this post which had no answer given: https://es.infragistics.com/community/forums/f/ultimate-ui-for-wpf/72598/setting-worldrect-of-xamgographicmap-no-calls-to-gettilelayers-of-custom-maptilesource

Some code:

    public class LocalMapTileSource : Maps.XamMultiScaleTileSource
    {
        public LocalMapTileSource() : base(3033, 3033, 256, 256, 0) { }
        private const string TileOriginalPath = @"C:\ProgramData\SmartSnow7\Tiles\{Z}\{X}\{Y}.png";

        protected override void GetTileLayers(int tileLevel, int tilePositionX, int tilePositionY, System.Collections.Generic.IList<object> tileImageLayerSources)
        {
            var zoom = tileLevel - 8;
            var invY = (int)Math.Pow(2.0, zoom) - tilePositionY - 1;
            if (zoom > 0)
            {
                var uriString = TileOriginalPath;
                uriString = uriString.Replace("{Z}", zoom.ToString());
                uriString = uriString.Replace("{X}", tilePositionX.ToString());
                uriString = uriString.Replace("{Y}", invY.ToString());
                tileImageLayerSources.Add(new Uri(uriString));
            }
        }
    }

        public InfragisticsMap()
        {
            InitializeComponent();
            GeoMap.BackgroundContent = new LocalMapImagery();
            GeoMap.WorldRect = new Rect(8.3713675, 46.7982968, 0.0119369, 0.0081759);
        }
