JavaScript ArcGIS AreaMeasurementAnalysis用法及代碼示例

AMD: require(["esri/analysis/AreaMeasurementAnalysis"], (AreaMeasurementAnalysis) => { /* code goes here */ });

ESM: import AreaMeasurementAnalysis from "@arcgis/core/analysis/AreaMeasurementAnalysis";

類： esri/analysis/AreaMeasurementAnalysis

自從：用於 JavaScript 4.23 的 ArcGIS API

AreaMeasurementAnalysis 計算多邊形區域的麵積並以 3D SceneView 顯示測量值。

要顯示 polygon 的麵積測量，請創建 AreaMeasurementAnalysis 的新實例，將其添加到 SceneView.analyses 並設置幾何屬性。

使用AreaMeasurementAnalysisView3D 檢索分析結果。

// create analysis
const areaMeasurement = new AreaMeasurementAnalysis({
  geometry: polygon
});

// add to scene view
sceneView.analyses.add(areaMeasurement);

// retrieve measured results from analysis view
const analysisView = await sceneView.whenAnalysisView(areaMeasurement);
await watchUtils.whenFalse(analysisView, "updating");

const result = analysisView.result;

使用AreaMeasurement3D 小部件添加交互性並允許用戶更改分析的幾何形狀。
