标签: openlayers tms

我在使用我的瓷砖项目时遇到了麻烦 到我的网络服务器并使用OpenLayers绘制 我的地图。

我们正在使用tilemill来设计地图样式> mbtiles 出口> mbutil到目录> openlayers.tms

我附上了我们正在使用的代码, 这是对OpenLayers.TMS的修改 示例

这是我的地图的链接,你会看到 问题,第一手:

建议?

使用以下代码修复它: http://wiki.openstreetmap.org/wiki/Talk:Openlayers_POI_layer_example

以下是MAP的代码:

<head>
<title>Markieta</title>
<script src="http://www.openlayers.org/api/OpenLayers.js"></script>
<script src="http://www.openstreetmap.org/openlayers/OpenStreetMap.js"></script>
<script type="text/javascript">

    var map;

            function osm_getTileURL(bounds) {

            var res = this.map.getResolution();

            var x = Math.round((bounds.left - this.maxExtent.left) / (res * this.tileSize.w));
            var y = Math.round((this.maxExtent.top - bounds.top) / (res * this.tileSize.h));
            var z = this.map.getZoom();
            var limit = Math.pow(2, z);

            // ----

            if (y < 0 || y >= limit) {
                    return OpenLayers.Util.getImagesLocation() + "404.png";
                } else {
                    x = ((x % limit) + limit) % limit;
                //alert(this.url + z + "/" + x + "/" + y + "." + this.type);
                    return this.url + z + "/" + x + "/" + y + "." + this.type;
                }
    }

    function init() {
            var options = {
            projection: new OpenLayers.Projection("EPSG:900913"),
            displayProjection: new OpenLayers.Projection("EPSG:4326"),
            units: "m",
            numZoomLevels: 18,
            maxResolution: 156543.0339,
            maxExtent: new OpenLayers.Bounds(-20037508, -20037508,
                                             20037508, 20037508.34)
        };
        var navigation_control = new OpenLayers.Control.Navigation({});
        var controls_array = [
        navigation_control,
        new OpenLayers.Control.PanZoomBar({}),
        new OpenLayers.Control.LayerSwitcher({}),
        new OpenLayers.Control.Permalink(),
        new OpenLayers.Control.MousePosition({})
    ];

        OpenLayers.ImgPath = "http://js.mapbox.com/theme/dark/";

        map = new OpenLayers.Map('map', options, {
        controls: controls_array
    });

        var layer = new OpenLayers.Layer.TMS(
            "Markieta",
            "http://markieta.nfshost.com/ttctiles7/", {layername: 'ttc7', type: 'png'}
        );

        map.addLayer(layer);

        if(!map.getCenter()){
        map.setCenter(new OpenLayers.LonLat(-8835000,5427500),11);
    }
}

</script>
</head>
<body onload="init();">
<div id="map"></div>
<style type="text/css">
        body {
            margin: 0;
        }
        #map {
            width: 100%;
            height: 100%;
        }

        #text {
            position: absolute;
            bottom: 1em;
            left: 1em;
            width: 512px;
        }
</style>
</div>
</body>
</html>

但是,我仍然遇到OpenLayers.Controls课程的问题......我会把它留给另一天。 (正如你所看到的,没有创建panzoombar,layerswitcher,permalink和mouseposition ..)
