Question

使用leaflet加载wmts服务的地图，地图不显示。代码如下：

 var scalesArr = [
	5.575667832355465E8,
	2.7878339161777323E8,
	1.3939169580888662E8,
	6.969584790444331E7,
	3.4847923952221654E7,
	1.7423961976110827E7,
	8711980.988055414,
	4355990.494027707,
	2177995.2470138534,
	1088997.6235069267,
	544498.8117534633,
	272249.4058767317,
	136124.70293836584,
	68062.35146918292,
	34031.17573459146,
	17015.58786729573,
	8507.793933647865
]
    var map = L.map('map', {
        center: [116.49 , 39.85],
        maxZoom: 16,
        zoom: 0,
        crs: new L.Proj.CRS("EPSG:4326",
            {
                origin: [-179.1909461364443,85.13041252989518 ],
                scaleDenominators: scalesArr,
               
            })
    });
    L.supermap.wmtsLayer("http://172.16.15.252:8090/iserver/services/map-beijing-2/wmts100",
        {
            layer: "beijingMap_Blue",
            style: "default",
            tilematrixSet: "Custom_beijingMap_Blue",
            format: "image/png",
           // requestEncoding: 'REST',
           transparent : true
        }
    ).addTo(map);

  参数来源说明如下图图片：

L.Proj.CRS中origin的参数是经纬度坐标系下地图的左上角值

报错信息：

        从报错信息看应该是L.Proj.CRS("EPSG:4326")系下原点origin错误，但不知道如何获取才对

你好，你的报错，应该是没有正确填写wmts对接参数，所以获取不到瓦片。参考技术博客https://blog.csdn.net/supermapsupport/article/details/70214054介绍了iClient 如何使用 WMTS 地图服务
