ArcToolbox基础,2023/11/7,62,脚本和模型,脚本可以通过一个工具或多个工具实现一个简单或复杂的处理。因为数据不是特定的，所以脚本可以重复使用。在ArcToolbox中，用户可以通过把数据和工具拖放到模型中，来建立一个固定有序的处理复杂GIS任务的过程。脚本可以脱离ArcGIS的环境独立运行，模型不可以。,2023/11/7,63,ArcToolbox基本操作,激活扩展工具（参见Task 2-10）创建新的Toolbox管理工具,2023/11/7,64,Task 2:Introduction to ArcMap(1),1.You can start ArcMap by clicking the Launch ArcMap button in ArcCatalog or from the Programs menu.ArcMap is the main application for data display,data query,data analysis,and data output.ArcMap organizes data sets into data frames(also called maps).You open a new data frame called Layers when you launch ArcMap.Right-click Layers and select Properties.On the General tab,change the name Layers to Task 2 and click OK.,2023/11/7,65,2.Next add emidalat and emidastrm.shp to Task 2.Click the Add Data button in ArcMap,navigate to the Chapter 1 database,and select emidalat and emidastrm.shp.To select more than one data set to add,click the first data set and then click other data sets while holding down the Ctrl key.An alternative to the Add Data button is the drag-and-drop method.You can add a data set in ArcMap by dragging it from the Catalog tree and dropping it in ArcMaps view window.,Task 2:Introduction to ArcMap(2),2023/11/7,66,3.A warning message states that one or more layers are missing spatial reference information.Click OK to dismiss the dialog.emidastrm.shp does not have the projection information,although it is based on the UTM coordinate system,same as emidalat.You will learn in Chapter 2 how to define a coordinate system.,Task 2:Introduction to ArcMap(3),2023/11/7,67,4.Both emidastrm and emidalat are highlighted in the table of contents,meaning that they are both active.You can deactivate by clicking on the empty space.The table of contents has three tabs:Display,Source,and Selection.On the Display tab,you can change the drawing order of the layers by dragging and dropping a layer up or down.The Source tab shows the data source of each layer.(The Source tab also lists tables that have been added.)The Selection tab lets you choose the selectable layer.Q3.Does ArcMap draw the top layer in the table of contents first?,Task 2:Introduction to ArcMap(4),2023/11/7,68,5.The standard toolbar in ArcMap has such tools as Zoom In,Zoom Out,Pan,Select Elements,and Identify.When you hold the mouse point over a tool,a ToolTip appears in a floating box to tell you the name of the tool and a short message about the use of the tool appears at the bottom of the ArcMap window.,Task 2:Introduction to ArcMap(5),2023/11/7,69,6.ArcMap has two views:Data View and Layout View.(The buttons for the two views are located at the bottom of the view window.)Data View is for viewing data,whereas Layout View is for viewing the map product for printing and plotting.For this task,you will stay with Data View.,Task 2:Introduction to ArcMap(6),2023/11/7,70,7.This step is to change the symbol for emidastrm.Click the symbol for emidastrm in the table of contents to open the Symbol Selector dialog.You can either select a preset symbol(e.g.,river)or make up your own symbol for emidastrm by specifying the color,width,and properties of the symbol.Choose the preset symbol for river.,Task 2:Introduction to ArcMap(7),2023/11/7,71,8.Next classify emidalat into the elevation zones of 1300 meters.Right-click emidalat,and select Properties.Click the Symbology tab.Click Classified in the Show frame.Change the number of classes to 6,and click the Classify button.The Method dropdown list shows six methods.Select Manual.There are two ways to set the break values for the elevation zones manually.To use the first method,you will check the box to snap breaks to data values and then click the first break line and drag it to the intended value of 900.Then set the other break lines at 1000,1100,1200,1300,and 1337.To use the second method,you will click the first cell in the Break Values frame and enter 900.Then enter 1000,1100,1200,and 1300 for the next four ceils.(If the break value you entered is changed to a different value,reenter it.)Click OK to dismiss the Classification dialog.,2023/11/7,72,9.You can change the color scheme for emidalat by using the Color Ramp dropdown list in the Layer Properties dialog.Sometimes it is easier to select a color scheme using words instead of graphic views.In that case,you can right-click inside the Color Ramp box and uncheck Graphic View.The Color Ramp dropdown list now shows White to Black,Yellow to Red,etc.Select Elevation#1.Click OK to dismiss the dialog.,Task 2:Introduction to ArcMap(9),2023/11/7,73,颜色梯度（1）,2023/11/7,74,颜色梯度（2）,2023/11/7,75,10.ArcMap has access to several extensions including Spatial Analyst.Select Extensions from the Tools menu and check Spatial Analyst.Then select Toolbars from the View menu and check Spatial Analyst.The Spatial Analyst toolbar should now appear in ArcMap.Click the Spatial Analyst dropdown arrow,point to Surface Analysis,and select Slope.In the Slope dialog,select emidalat for the input surface and click OK to run the command.Slope of emidalat is the slope layer of emidalat.An alternative for Arclnfo users is to use ArcToolbox in ArcMap.The Slope tool in the Spatial Analyst Tools/Surface toolset can perform the same operation except that you have to save the output on disk.Spatial Analyst Tools are not available for ArcView users,2023/11/7,76,扩展模块的启动,2023/11/7,77,11.You can save Task 2 as a map document before exiting ArcMap.Select Save As from the File menu in ArcMap.Navigate to the Chapter 1 database,enter chap1 for the file name,and click Save.ArcMap automatically adds the extension.mxd to chapl.Data sets displayed in Task 2 are now saved with chapl.mxd.To re-open chapl.mxd,chapl.mxd must reside in the same folder as the data sets it references.You can save a map document with the relative path name option(e.g.,without the drive name).Select Map Properties from ArcMaps File menu.In the next dialog,click on Data Source Options.The Data Source Options dialog has the options of full path names and relative path names.,2023/11/7,78,空间分析工具栏,2023/11/7,79,存储路径,2023/11/7,80,12.To make sure that
