Exercise 1: Getting to know ArcGIS

The Scenario You are working for the California Visitor s Commission. You have been asked to prepare a map of California for several dignitaries from out of the country. Your map will need to include enough information to help them understand the size and diversity of the state. Exercise 1: Getting to know ArcGIS Earth System Research Institute (ESRI) is the leading GIS software developer. Their software is used throughout the world in every type of industry. ESRI has also worked to develop a network of users. This includes regional and international conferences as well as their web site. The basic GIS software developed by ESRI is called ArcGIS. However, they offer several levels of licences, namely ArcView, ArcEditor and ArcInfo. The appearance and basic tools found in each licence level are virtually the same. The only variation is an increasing number of advanced tools available. The software is also available with a variety of extensions used to perform specific types of geoprocessing tasks. In this exercise you will: access GIS data preview data in ArcCatalog begin an ArcMap document use common tools in ArcMap select features in ArcMap export and save a map

Exercise 1: Getting to know ArcGIS Connecting to folders in ArcCatalog and copying data 2 1. Begin by opening ArcCatalog. You will find a shortcut to this software on the desktop or via the Start button under All Programs. By default, ArcCatalog is only connected to a limited number of folders. You need to connect to other folders and files you want to be able to use in ArcCatalog. 2. Click the Connect to folder button. This will open the Connect to Folder dialog box. 3. Navigate to the folder you want to connect to ArcCatalog. Select that folder and click OK. This will include the location where data for this exercise is stored as well as your portable memory device. Your instructor will let you know where the data for this exercise is stored. For this exercise, we will use the California data folder. You will need to copy the data onto your own computer or personal memory device. 4. In ArcCatalog, navigate to the folder that contains the exercise data, right click the California data folder and select Copy. 5. Navigate to your portable memory device or to the C drive, right click in the white portion of the folder contents window, and select Paste. 3 4 Page 2

Exercise 1: Getting to know ArcGIS Exploring data in ArcCatalog Now that you have copied the data to your own personal computer, you will use several tools available in ArcCatalog to explore the data available. ArcCatalog is organized much like you would find in Windows Explorer. On the left side you find a catalog tree pane which displays available files. These include the default files as well as the files that you have connected to in the previous step. On the right is the data frame pane. You will explore these tabs. The contents tab again, looks like what you would find in windows Explorer with one exception. This tab will only display file folders and spatial data usable in ArcGIS. 1. Explore the folders found in the California data file. You will notice that each sub-folder has at least one file. These are all spatial data files referred to as Shapefiles. 2. In the catalog tree pane, select the California File Folder. 3. Click the Preview tab. You will be given a message that states that the selection cannot be previewed. The Preview tab is used to preview spatial data. 4. In the catalog tree, navigate to, and select a Shapefile. You will notice several changes. First, you can see a preview of your Shapefile. Also, you notice that the tools in the Geography toolbar are now active. Finally, you will notice at the bottom of the pane a drop down menu to modify the preview format. You will explore the tools on the Geography toolbar as well as some of the preview options. Catalog Tree Pane 4 Data View Pane 3 Geography toolbar active Preview of data Preview drop down options Page 3

To the right, you will see the function of each of the tools on the Geography toolbar. 5. Click and use the Zoom In, Zoom Out and Pan tools to navigate around the Shapefile preview. 6. Click the Full Extent button to return to viewing the full extent of the Shapefile in the data view pane. 7. Click the Identify tool to use that tool and then click on one of the features in the Shapefile. The Identify results dialog box will open. This dialog box displays all of the information stored in the attribute table for that particular feature. Now, you will preview the attribute table in ArcCatalog. 8. Close the Identify Results dialog box by clicking the red X in the upper right hand corner. 9. Click the drop down menu at the bottom of the data view pane and select Table. This will change the data view window to a tabular display. Each row in the table corresponds to a feature in the shapefile. You will now be using this data in ArcMap. Return to the Content tab.

Exercise 1: Getting to know ArcGIS Creating a new ArcMap Document 1. Open ArcMap. This can be done several ways. You can access the shortcut via the desktop or Start command button. Also, if you have ArcCatalog open, you can click the Launch ArcMap button on the Standard tool bar on ArcCatalog. As ArcMap opens, a dialog box will appear, asking what Map document you want to open. 2. Select A new empty map and click OK. This will close the beginning ArcMap dialog box and open an empty ArcMap document. 1 2 Page 5

Exercise 1: Getting to know ArcGIS Adding data to an ArcMap Document 1 There are two ways to add data to an ArcMap document. We will explore both. 1. Click the Add Data button found on the Standard toolbar. This will open the Add Data dialog box. 2. Navigate to the file folder where you stored the California data. Navigate into the Outline folder and select cal_ base.shp. The Add Data dialog box will navigate to connected folders. The Connect to Folder button is available on the toolbar in this dialog box. 3. Click Add to add the cal-base Shapefile to the map document. The other method to add data to an ArcMap document is to drag and drop the data directly from ArcCatalog. 4. Arrange both the ArcMap interface and the ArcCatalog interface so you can see both applications on your screen. 5. In ArcCatalog catalog tree, Navigate to the folder where you stored the California data and navigate directly into one of the data folders so the Shapefile appears in the Data View pane. 6. Left Click on the Shapefile icon and hold the left mouse button down. 3 2 Page 7

7. While holding the mouse button down, drag your mouse over to the Table of Contents on ArcMap. A thick black line will appear in the Table of Contents. 8. Move your mouse up and down so the thick black line is in the correct level where you would like to place your data. 9. Release the mouse button. The Shapefile will be placed in the ArcMap Document. 10. Continue to add other data from the California data folder to the ArcMap document using either method. Exercise 1: Getting to know ArcGIS Thick black line appears 8 Helpful Hints The data frame will use the same measurement units and projection (known as the spatial reference) as the first layer you add. If you add a layer that had a different spatial reference, a dialog box will let you know. ArcMap will automatically re-project the data to match the spatial reference of the data frame. As data is added to an ArcMap Document, the data will be stacked on top of each other. This will make it difficult to see the bottom layer if the top layer covers the entire area. To rearrange the data in the table of contents, you can left click the layer name and drag it higher or lower in the table of contents. Page 8

Changing Basic Symbology In the task, you will modify the basic symbology of the Shapefiles in ArcMap. Later in the manual, you will learn more advanced symbology methods. Before we begin, be sure you have added the Earthquakes, Populated Places, Lakes, Rivers, and Counties Shapefiles to your ArcMap document. 1. Left click the layer symbol you wish to modify. This will open the Symbol Selector dialog box. You may choose one of the preset symbols or modify the fill and outline properties. 2. If you choose to use one of the preset symbols, click on the preset symbol and jump to step 6 below. 3. Click the drop down menu to the right of the fill color and select the color you wish for the fill color. 4. Click the drop down menu to the right of the outline color and select the color you wish for the outline color. 5. Modify the thickness of the outline using the Outline Width value. You may use the up and down arrows or type in a value. Your symbol settings will be shown in the Preview box. 6. Click OK to close the Symbol Selector dialog box and apply the changes you made. Expand or Collapse Symbology View or Hide Layer Exercise 1: Getting to know ArcGIS Data Frame Name Layer Name Layer Symbol 3 5 4 Symbol Preview Helpful Hints The Symbol Selector dialog box will give options applicable to point, line or (as shown to the right) polygon features depending on the type of feature you are using. When working with polygons, you can choose No Color for the fill if you would like to have hollow symbols. You can also choose No Color for the outline if you would like to eliminate the boundary lines. Preset Symbols 6 Page 9

Explore the other tools. Later in the manual you will learn more about the Hyperlink tool. 10 Page 13

Exercise 1: Getting to know ArcGIS Save and export an ArcMap document In this task you will save you map document and learn to export your map in a variety of formats. 1. Modify your map including the extent shown in the data frame, layers turned on or off, and the symbology of the layers. 2. Click Clear Selected Features on the Tools toolbar. 3. Click File on the Main menu and select Save. This will open the Save As dialog box. 4. Navigate to the folder where you stored the other California data. 5. Specify a name for your map document. 4 Helpful Hints Remember that the ArcMap document does not save a copy of the data, it only saves the file path to the data. If you move or modify your data, you will loose that data in your ArcMap document. An ArcMap document will save the symbology, spatial extent, and other many settings. 5 6 Page 14

6. Click Save to save your map document. 7. Click File on the Main menu and select Export Map. This will open the Export Map dialog box. 8. Navigate to the folder where you would like to export a copy of your map. 9. Specify a name for your exported copy of your map. 10. Using the drop down menu, choose the format in which you would like to export your map. 11. Click Save to export a copy of your map. Exercise 1: Getting to know ArcGIS 8 Want More? When you export and are viewing the Data View you export just what is in that Data View. What happens if you are Layout View?
