概要

cesiumで現在地取得してみた。

サンプルコード

var viewer = new Cesium.Viewer('cesiumContainer');
viewer.canvas.addEventListener('click', function(e){
    var mousePosition = new Cesium.Cartesian2(e.clientX, e.clientY); 
    var ellipsoid = viewer.scene.globe.ellipsoid;
    var cartesian = viewer.camera.pickEllipsoid(mousePosition, ellipsoid);
    if (cartesian) 
    {
        var cartographic = ellipsoid.cartesianToCartographic(cartesian);
        var lon = Cesium.Math.toDegrees(cartographic.longitude).toFixed(5);
        var lat = Cesium.Math.toDegrees(cartographic.latitude).toFixed(5); 
        alert(lon + ', ' + lat);
    }
    else
    {
        alert('Globe was not picked');
    }   
}, false);
viewer.camera.flyTo({
    destination: Cesium.Cartesian3.fromDegrees(139.60, 35.60, 100000.0),
});
