Question

调用代码

	url = mapParm.mapNames.mapUrl;
	url = host+url;
	lonlat_x = mapParm.mapNames.longitude;	//经度
	lonlat_y = mapParm.mapNames.latitude;	//纬度
	map_zoom = mapParm.mapNames.zoom;
	level = "1";
	vecotrLayer = new SuperMap.Layer.Vector("vectorLayer");
	map = L.map('map', {
	    center:[ lonlat_y,lonlat_x ],
	    dragging:true,
        doubleClickZoom:true,
        logoControl:false,
        attributionControl:false,
        scrollWheelZoom : true, // 滚轮缩放
        zoomControl : true, // 缩放控件
        zoom:0,
	    maxZoom:5
	});
	L.supermap.tiledMapLayer(url, {
	    transparent: true
	}).addTo(map);

调用后 只显示字 没有地图

地图信息

添加转换代码后可以显示别的地图

url = mapParm.mapNames.mapUrl;
	url = host+url;
	lonlat_x = mapParm.mapNames.longitude;	//经度
	lonlat_y = mapParm.mapNames.latitude;	//纬度
	map_zoom = mapParm.mapNames.zoom;
	level = "1";
	vecotrLayer = new SuperMap.Layer.Vector("vectorLayer");
	var crs = L.Proj.CRS("EPSG:4326", {
		origin: [120.08,36.37],
	    scaleDenominators: [6000,3000,1500,500,200,100,50],
	    bounds:[120.08, 36.35,120.1, 36.37]
	});
	map = L.map('map', {
	    crs: crs,
	    center:[ lonlat_y,lonlat_x ],
	    dragging:true,
        doubleClickZoom:true,
        logoControl:false,
        attributionControl:false,
        scrollWheelZoom : true, // 滚轮缩放
        zoomControl : true, // 缩放控件
        zoom:0,
	    maxZoom:5
	});
	L.supermap.tiledMapLayer(url, {
	    transparent: true
	}).addTo(map);

但是显示哪张原坐标系地图会报错

Answer 1

您好，这个32651的坐标系需要在前端加载的时候自定义，可以参考https://blog.csdn.net/qq_35833374/article/details/97798345

通过proj4自定义坐标系信息加载rest地图服务

我使用proj4转换可以显示地图了 可以设置地图使用经纬度吗

Proj4js.defs("EPSG:32651","+proj=utm +zone=51 +datum=WGS84 +units=m +no_defs");
	var crs = L.Proj.CRS("WGS84", {
		origin: [238354.12,4028108.24 ],
	    bounds: L.bounds([234119.7 , 4022197.83] ,  [243282.63 , 4033298.93])
	});
	map = L.map('map', {
	    crs: crs,
	    center:[ lonlat_y,lonlat_x ],
	    dragging:true,
        doubleClickZoom:true,
        logoControl:false,
        attributionControl:false,
        scrollWheelZoom : true, // 滚轮缩放
        zoomControl : true, // 缩放控件
        zoom:3,
	    maxZoom:5
	});
	L.supermap.tiledMapLayer(url, {
	    transparent: true
	}).addTo(map);
