0.引言
ArcGIS For JS 是一种用于创建和编辑地理信息的 JavaScript 库,它允许用户在线编辑 ArcGIS Server 发布的几何要素。本文从ArcGIS创建几何要素、编辑要素,然后发布要素到ArcGIS Server,最后由ArcgisForJS访问A如此GIS Server发布的几何要素。
1.ArcGIS创建几何要素
(1)新建一个mxd地图文档,命名geoedit。
(2)新建点、线、面要素
创建要素时,添加字段,名称:va,类型:文本。
创建结果如下:
(3)注册要素
(4)编辑点、线、面要素
设置各要素的值,以下以点为例:
再设置线要素和面要素的va值。
(5)设置点、线、面样式
(6)可以保存要素为模板
2.ArcGIS Server发布几何要素
在ArcGIS Server中查看发布的几何要素。
REST URL:http://localhost:6080/arcgis/rest/services/geoedit/FeatureServer
3.ArcgisForJS在线编辑ArcGIS Server发布的几何要素

map: map, // References the map object created in step 3
zoom: 3,

});
// Editor widget
const editor = new Editor({
view: view
});
// Add widget to the view
view.ui.add(editor, "top-right");
});
