在本範例中,我們將示範如何設定飛行路徑,點擊圖面取得圖徵查詢結果,說明如下:
<範例>
var earth_ = null; var VLayer = null;
function documentLoad() { document.body.style.overflow = "hidden"; SuperGIS.Initialize("/ServerGate/", function () { SuperGIS.ServerEarth.Initialize(InitEarth); }); }
function InitEarth() { var pBody = new SuperGIS.Windows.HTMLContainer(document.getElementById("example"));
var sHost = location.href; var idx = sHost.indexOf("/", 8); if (idx >= 0) sHost = sHost.substring(0, idx); CreateHTML5Earth(pBody, function (pEarth) { EarthLoaded(pEarth); });
function EarthLoaded(pEarth) { earth_ = pEarth; pEarth.Scene.BackgroundColor = pEarth.CreateColor(0, 0, 0, 1); pEarth.SetupSystem(true, s_WGS84); pEarth.SetupSkin(pEarth.CreateEnvelope(-180, 180, -90, 90, s_WGS84), sHost + "/ServerGate/Skin1.jpg"); pEarth.MajorGraticule.Visible = false; pEarth.MinorGraticule.Visible = false;
// 指定向量磚服務的 WMTS 網址, 欲加入的圖層名稱, 及 callback function 名稱 VLayer = new SuperGIS.VectorLayer(getDataServicePath() + 'project_block/SimpleWMTS.aspx', pEarth, { layer: '土地使用分區' }, LanduseFinish);
pEarth.SetViewpoint(120.656, 24.160, 500, 0, 50, true); }
// 在 callback 中設定每個 feature 的符號樣式 function LanduseFinish(array) { var rv = 128, gv = 255, bv = 128; for (var i = 0; i < array.length; i++) { var mark = array[i]; var fc = earth_.CreateColor(rv / 255.0, gv / 255.0, bv / 255.0, 128 / 255.0); mark.ReplaceZ = 0.5; // 設定高程 (公尺) mark.DDDSymbol = earth_.CreateSimpleDDDFillSymbol(earth_.CreateModelMaterial(0, fc), null); mark.Queryable = true; // 設定為可查詢 } } } function QueryClick() { var invalue = document.getElementById("invalue").value; var exp = "[分區簡稱]=" + invalue;
array = VLayer.ExpQuery(exp); // 對此向量磚圖層進行屬性查詢, 格式 "[FIELD]=value", 回傳查詢到的結果陣列 if (array.length > 0) { var mark = array[0]; // 取第一個結果 var geo = mark.Geometry;
var cx = (geo.getMinX() + geo.getMaxX()) / 2; var cy = (geo.getMinY() + geo.getMaxY()) / 2; earth_.SetViewpoint(cx, cy, 300, 0, 0, false); // Camera 移至此 Feature 中心 } }
