1、ArcGIS Engine基礎(chǔ)介紹,Esri西安分公司 姚嘯,介紹內(nèi)容,ArcGIS Engine簡(jiǎn)介 創(chuàng)建第一個(gè)ArcGIS Engine程序 練習(xí)DEMO,ArcGIS Engeine簡(jiǎn)介,ArcGIS Engine Developer Kit,開發(fā)包是組件, APIs 和工具的集合 開發(fā)人員可以用來創(chuàng)建高級(jí)的 GIS 應(yīng)用 組件 Engine 庫 制圖、繪制、選擇、編輯等 Control 庫 地圖控件、布局控件、工具條等 APIs COM、.NET、Java、C+ 工具 文檔、開發(fā)工具,ArcGIS Engine功能框架,基本服務(wù) 應(yīng)用層需要用到的 ArcObjects 核心對(duì)象 幾何圖

2、形的操作與顯示 數(shù)據(jù)訪問 地理數(shù)據(jù)集，矢量，柵格數(shù)據(jù) 地圖分析 屬性、空間查詢，地理數(shù)據(jù)處理 地圖顯示 渲染、標(biāo)注、制圖表達(dá) 開發(fā)組件 各種應(yīng)用層面上的 Control 及 Commands layer.ShowTips = true;,ToolTip tootip1 = new ToolTip; tootip1.SetToolTip(axMapControl1,這是一個(gè)提示);,PageLayoutControl控件,PageLayoutControl 封裝PageLayout coclass 繪制地圖元素 創(chuàng)建版面視圖 打印 設(shè)置當(dāng)前工具 加載地圖文檔 庫 PageLayoutContro

3、l.ocx,PageLayoutControl控件,使用PageLayout 來訪問其它對(duì)象 Elements(例子代碼 MapElements) FrameElements MapFrame MapSurroundFrame GraphicElements PictureElements,使用elements,關(guān)于elements有很多高級(jí)的成員函數(shù) IPageLayoutControl AddElement FindElementByName LocateFrontElement GraphicsContainer,地圖上顯示查詢結(jié)果element,查詢結(jié)果的渲染,ISimpleMarke

4、rSymbol simpleMarkerSymbol = new SimpleMarkerSymbolClass(); simpleMarkerSymbol.Color = rgb; simpleMarkerSymbol.Size = 30; IMarkerElement markerElement = new MarkerElementClass(); markerElement.Symbol = simpleMarkerSymbol; element = (IElement)markerElement; element.Geometry = point; graphicsContainer

5、 = (IGraphicsContainer)map; graphicsContainer.AddElement(element, 0);,使用地圖文檔,MXD 文件是結(jié)構(gòu)化的存儲(chǔ)文檔(保存路徑) 通常由ArcMap創(chuàng)建 包含持久對(duì)象 Maps, Layers, PageLayout, MapDocument 使以下成為可能 讀取 mxd, lyr, mxt, and pmf files 寫新的 mxd files 訪問map document的內(nèi)容,IMapDocument與mxd,讀取和寫地圖文檔的成員函數(shù) Open: 打開已經(jīng)存在的地圖文檔 (mxd, mxt, lyr, pmf) Sa

6、veAs: 保存當(dāng)前文檔到新的文件 CheckMxFile：檢查mxd是否存在 LoadMxFile：加載mxd文檔 ReadMxMaps：讀mxd文檔 New:新建mxd文檔 Save:保存mxd文檔,加載mxd,LoadMxFile,if (openFileDialog2.ShowDialog() = DialogResult.OK) string FilePath = openFileDialog2.FileName; if (axMapControl1.CheckMxFile(FilePath) axMapControl1.MousePointer = ESRI.ArcGIS.Cont

7、rols.esriControlsMousePointer.esriPointerHourglass; axMapControl1.LoadMxFile(FilePath, 0, Type.Missing); axMapControl1.MousePointer = ESRI.ArcGIS.Controls.esriControlsMousePointer.esriPointerDefault; else MessageBox.Show(FilePath + is not a vaild ArcMap document); return; ,訪問地圖文檔中的對(duì)象,控件可以直接引用對(duì)象 (Map

8、 and PageLayout) 或訪問自己的拷貝 Reference 直接 Copy 使用ObjectCopy 避免共享引用 深度復(fù)制,IMapDocument mapdoc = new MapDocument(); axMapControl1.Map = mapdoc.get_Map(0) ;,IObjectCopy objectcopy = new ObjectCopyClass(); IPageLayout pagelayout = objectcopy.Copy(mapdoc.PageLayout) as IPageLayout;,框架控件,ToolbarControl 和 TOCC

9、ontrol 被設(shè)計(jì)成和其它控件協(xié)同工作 通過一個(gè)buddy控件自動(dòng)捆綁在一起 根據(jù)彼此的狀態(tài)通信和同步 例子: active tool, layer visibility,Buddy Control,Toolbar,TOC,命令和工具,提供超過 100 個(gè)工具和命令,TocControl,顯示所有的圖層和符號(hào) Simple symbols, renderers Group layers 控制圖層可視性 必須調(diào)用SetBuddyControl 庫 TOCControl.ocx,ToolbarControl,自定義 commands, tools 和 menus的容器 允許命令和以下控件對(duì)象進(jìn)行

10、交互 Map, PageLayout, Scene, 和 Globe 必須調(diào)用 SetBuddyControl 庫 ToolbarControl.ocx,制圖控件命令,系統(tǒng)提供的控件命令, 工具, 工具條, 和菜單 命令和工具 漫游, 縮放, 打開地圖, 圖形繪制, 工具條 要素選擇, 繪圖, 地圖導(dǎo)航, 和 pagelayout 菜單 要素選擇和地圖瀏覽 庫 esriCommandControls.olb 參考 對(duì)象模型圖或技術(shù)文檔,創(chuàng)建第一個(gè)ArcGIS Engeine應(yīng)用程序,創(chuàng)建一個(gè)控件應(yīng)用程序 使用控件成員 使用工具條和TOC控件 加載 MXD 文檔 保存mxd文檔 打開shp,開發(fā)
