By default, the lessons are installed to ―C:\HECRAS Training‖ subdirectory. You can find the required files to plete this lesson in the subdirectory, SNET\Lesson 1\initial. In this subdirectory you will find the following files: 本課中，我們在 HECRAS Training CDROM上提供了一些 HECRAS程序訓(xùn)練中只讀存儲器的數(shù)據(jù)。在這個子目錄中你可以找到下列文件： ? Excel spreadsheet that holds the cross section data. 橫截面數(shù)據(jù) 電子表格保存了橫截面的數(shù)據(jù) ? This JPG image is an image of cross section 3090 that will be added to the river model. 此 JPG圖是即將增設(shè)在河道模型上的橫截面 3090的圖。 ? This TIFF image will be used to help us create the river reach in this lesson. This file is not required. 在這一課中，此 TIFF圖將被用來幫助我們新建河段。 16 We found this DOQ image from the USGS Earth Explorer web site: 在 USGS Earth Explorer網(wǎng)站我們發(fā)現(xiàn)了 DOQ圖 You can find many other sources of DOQ images by searching for DOQ on any of the major inter search engines. 通過在任何一個主要的網(wǎng)絡(luò)搜索引擎中搜索“ DOQ”，都能找到許多其他 DOQ的資料。將打開本課的方案。 . 17 39 14 HECRAS Figure Add/Edit background picture for the schematic button 圖 增加 /編輯示意背景圖片按紐 HECRAS will then display the Background Pictures on Schematic dialog as shown in Figure . Next click the button labeled Add, and select the image in the Lesson 1\initial subdirectory and click Open. After you open the image, HECRAS will prompt you to find out if you want to extend the schematic extents to match the extents of the image. Click Yes to the message. HECRAS 顯示如圖 Background Pictures on Schematic對話框，然后點擊Add按紐，并在 Lesson 1\initial子目錄中選擇 ，點擊 Open。從幾何數(shù)據(jù)編輯器中選擇 View | Full Plot（視圖 /全屏顯示）。 使用放大鏡指針，畫出需要研究的區(qū)域。選擇 Set to Current View。 In the georeferenced image that we imported, we had previously shifted the reference coordinates so that the lower left reference point was at 0,0. However, when importing other georeferenced images, such as orthophotos that use state plane coordinates or UTM coordinates, the lower left coordinate will be in the millions for X,Y. HECRAS will not realize that the image coordinates start at such a high value. Therefore, you will have to manually set the lower left coordinates using the View | Set Schematic Plot Extents mand as we just previously did. 在我們輸入的以地理意義上的圖象中，我們先前跳過參考物，因此左邊的參考點是0,0。點擊 River Reach按紐并且連接背景圖象的斑點。 19 Note: There are two things that you should be aware of when creating a river reach. First, to undo the last point you created, right click the mouse. Secondly, to finalize the river reach, doubleclick the last point of the river reach. 注釋 ：在創(chuàng)建一個河流流程的時候有兩點值
