Question

我正在尝试使用传单API来显示有关全球珊瑚礁位置的数据。我最初下载了shapefile（.shp），然后使用QGIS将其转换为GeoJSON。我将数据放在项目文件夹中，但是当我尝试通过Ajax请求在传单上显示此数据时，浏览器花费了很长时间加载并最终返回了无响应的消息。但是，我可以看到标记会出现在地图上，尽管速度很慢。是否可以创建较小的文件或更有效地加载数据，从而不会使整个站点无法使用？

我的Ajax请求看起来像这样：

$.ajax({
        type: 'GET',
        url: './coldwater.geojson',
        dataType: 'json',
        data: data,
        success: function (data) {
            L.geoJSON(data).addTo(mymap);
        }, error: function(){
            console.log('Couldn\'t load data');
        }
    });

这是geoJSON的代码段

使用Google Maps API会更好吗？还是有更好的方法将shapefile插入传单地图中？
