一、创建Draw实例const draw = new Draw({ view: view});二、绑定绘制按钮的点击事件let action = draw.create("polygon");// PolygonDrawAction.vertex-add// Fires when user clicks, or presses the "F" key.// Can also be triggered when the "R" key is pressed to redo.action.

一、缘由最近项目中用到了画圆和画扇形，所以写出来二、PolygonThe first and last points of a ring must be the same环的第一点和最后一点必须相同A polygon contains an array of rings and a spatialReference.边形包含环数组和空间引用//3D polygon rings with m-values (note that the second ring does not have

1，执行命令npm init @vitejs/app vue-arcgisvue-arcgis是文件名选择框架，vue，回车选择JavaScript或者TypeScript,我选择的JavaScript2，按照提示命令执行查找项目目录：cd vue-arcgisnpm installnpm run dev3，新建集成终端、安装处理arcgis找到项目目录：\vue-arcgis>运行：npm install @arcgis/core将项目目录中node_modul

一、概述import FeatureLayer from “@arcgis/core/layers/FeatureLayer”;ES模块最新的引入方式，对vue这鸡儿很友好支持Map Service or Feature Servicelayer = new FeatureLayer({ id: layerid, //图层唯一ID title: layerItem.name, //图层名称 url: layerItem.url, //REST地图服务的URL visible: l

1. Map1、存储，管理和覆盖 2D和3D查看共同的图层的属性和方法; 2、地图实例仅仅只是容器，进行渲染还是靠MapView或者SceneView3、单个地图实例可以被多个视图引用即MapView和SceneView同时存在，因此地图图层交互发生在view上而并不是map//先创建地图实例const myMap = new Map({ basemap: "streets-vector"});//渲染const view = new MapView({ map: myMa

一、引用使用Vue+arcgis4.18怎么使用map我就不多说了，自己去官网看import Point from "@arcgis/core/geometry/Point";import GraphicsLayer from "@arcgis/core/layers/GraphicsLayer";二、Graphics为什么先写Graphics，因为Graphics可以挂（个人的理解）在GraphicsLayer上1，属性其实不搞那些花里胡哨的只需要var polylineGr

一、下载arcgisAPI二、将api放入项目public文件夹下类似三、安装esri-loader并引用cssimport{loadModules}from'esri-loader'import '../public/api/esri/themes/light/main.css'四、设置全局变量Vue.prototype.$loadModules=loadModules;Vue.prototype.$option={url:"./a...
