在leaflet.js文档中,记录了一个带有标记层的示例。我想用GeoJSON格式创建一个多边形层。这可能吗?
我为每个GeoJSON多边形定义了一个变量,名为route1,route2等。我的.js文件如下所示:
var map = L.map('map', {
center: [55.676098, 12.568337],
});
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: '© <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);
//============
//Create layer
//============
var Southroutes = new L.layerGroup([route1, route2, route3, route4, route5]);
L.geoJSON(Southroutes).addTo(map);
答案 0 :(得分:0)
您可以在添加到地图之前连接geojson对象。
var features = [];
[route1, route2, route3].forEach(function(route){
features = features.concat(route.features);
})
var Southroutes = L.geoJSON({
"type": "FeatureCollection",
"features": features
}).addTo(map);
或者,只需使用leaflet.js geojson addData
var Southroutes = L.geoJSON().addTo(map);
[route1, route2, route3].forEach(function(route){
Southroutes.addData(route);
})
(Fiddle)
