1 WHAT S NEW IN ARC CGIS 10-5 THINGS YOU SHOUL LD KNOW! (OK, THERE S ACTUALLY MORE THAN 5 HERE) Stacey Maples GIS Specialist and Instruction Coordinator, Yale University Map Department stacey.maples@yale.edu USER INTERFACE 1. Open ArcMap by going to the ArcGIS Program Group and Selecting ArcMap 10. Notice that this interface is considerably different from the previous. The Standard Toolbar has a new set of buttons to the right of the Edit Toolbar Button. These new buttons provide direct access to a number of new Dockable panels in the new AcMap interface. From the left, these buttons launch: a. The Table of Contents The Table of Contents is open, by default, but if you lose it, here s how to find it! b. Catalog Window The new Arc Catalog Window, now integrated into ArcMap. This one is enabled (and tabbed) by default, too. c. Search Window A new Integrated Search Tool for the ArcMap Interface. This is where the eminently helpful ArcToolbox Search Tab has gone. d. ArcToolbox The traditional ArcToolbox Window, sans the Search Tab, which has been relocated to the Search Tab. e. Python Window An Python Script editing panel, now integrated into ArcMap. f. Model Builder Direct access to the Model Builder interface. ARCCATALOG INTEGRATION & THE HOME FOLDER 2. If it is not already open, Click on the Catalog Window button to open the Catalog Window, then use it s pushpin to pin it in the open position. Note the items available in the default view of the Catalog Window. In particular, note the Home Documents\ArcGIS item at the top of the Catalog Window. 3. Right-click on the Folder Connections item and create a new connection to the folder containing the workshop data (as directed by the presenter). 4. Expand the newly connected workshop folder and drag the Yale_Sports.mxd into the Data Frame of ArcMap.

2 Take another look at the changes at the top of the Catalog Window. Your Home folder should now be set to the workspace that contains the Yale_Sports.mxd, providing convenient access to the data and files relevant to the current project. DOCKABLE WINDOWS 5. Click on the Search Tab, at the right side of the Data Frame, or use the Search Window Button, on the Standard Toolbar, if it is not visible. Use the pushpin to pin the window open. 6. Click-Hold-Drag the Search Window (using its Title Bar) and hover over the Catalog Window until a cluster of four Dock Targets appear.. Drop the Search Window onto the bottom target to dock the Search Window below the Catalog Window. (Hover over the boundary between the two windows to resize them). GEOPROCESSING TOOLS ON THE MAIN MENU At ArcMap 10, a new Geoprocessing Menu has been added to the Main Menu, providing access to the most frequently used Geoprocessing Tools from the ArcToolbox. If the default list is not exactly what you need in your daily workflows, you can customize it (just as you can with any of the ArcGIS menus and toolbars) in Customize Mode. 7. Click on the Commands Tab and scroll through the available commands to find the Analysis Tools and drag the Create Thiessen Polygons command to your Geoprocessing menu. Add any other command to the menu. 8. Close the Customize Mode Dialog.

3 SEARCH IN ARCGIS 10 Search in ArcMap has been integrated into the Search Window. From this window, you can search tools and data on your own Desktop, within your Enterprise (if Search Services are implemented) as well as ArcGIS.com content. 1. Start with a local search on the term water and note that the Search Window returns items from the ArcToolbox. Clicking on the tool name will launch the ArcToolbox Tool, while clicking on the tool path (in green) will locate the tool in ArcToolbox the hierarchy. 2. Now click on the Index / Search Options Button to the left of the Search Type dropdown and Add the folder containing the data for this workshop to the Registered Folders and Server Connections list. Then click the Index New Items button and wait for indexing to finish. Click OK. 3. Now, use local search to search on the term sports. Indexing makes your data and maps searchable in ArcMap. 4. Now, change the Search Type to ArcGIS Online and search on the term water again. Click through the All, Maps, Data & Tools filters to see the different types of ArcGIS Online Content you can add directly to ArcMap. IMAGE ANALYSIS The Image Analysis Window brings basic image tools to the ArcMap application. Common Image enhancement tools and a few analysis tools, are aggregated into a single interface. The real andvance here is how ArcGIS implements enhancements and analysis using Image Layers. These layers, like Layer Files, contain the instructions for enhancing and transforming imagery data, without containing the data, itself and reducing the need for redundant storage of image geoprocessingg results. 1. On the Main Menu, go to Windows>Image Analysis. Pin the Image Analysis Window open. 2. Enable the Draw Toolbar, and place it at the bottom of the ArcMap Window. EDITING IMAGERY - CLIP 3. Click on the _NAIP_4_Color_Band_Orthophotography1 layer to select it. 4. Use the Draw Rectagle Tool to create an are of interest that encompasses the Yale Bowl, and the Baseball Field. 5. Click on the Clip Button and note that the Image Analysis Window will create a new Image Layer called Clip NAIP_4_Color_Band_Orthophotography1 6. Use the Select Elements tool to select and delete the graphic area of interest.

4 7. Uncheck the original _NAIP_4_Color_Band_Orthophotography1 _NAIP_4_Color_Band_Orthophotography1 layer to view the result of the Clip tool. ANALYZING IMAGERY -NDVI 1. Click the Image Analysis Options button, at the top left of the Image Analysis window. 2. In the NDVI Tab, set Red Band: 3 and Infrared Band: Click on the Clip_NAIP_4_Color_Band_Orthophotography1 _NAIP_4_Color_Band_Orthophotography1 layer to select it, then click on the NDVI Button, in the Processing Panel of the Image Analysis Window. 4. Close the Image Analysis Window. IMAGE LAYER FILES & FUNCTIONS The functions that define this Image Layer are the accumulation of the previous analysis and transformation steps we applied to our original dataset. This can be seen in the Functions Tab of the Properties Dialog for the Image Laye Layer. Suppose we decide that we want to apply the NDVI calculation to the original extent of our dataset. This is easily accomplished by simply deleting the Clip Function in our layer. 1. Right-click click and Copy the NDVI_Clip NAIP_4_Color_Band_Orthophotogra NDVI_Clip NAIP_4_Color_Band_Orthophotography1 layer, then Paste it back into the Table of Contents. 2. Right-click on the NDVI_Clip NAIP_4_Color_Band_Orthophotography1 NDVI_Clip NAIP_4_Color_Band_Orthophotography1 and open its Properties. 3. Select the Functions Tab and take a look at the items in this tab. 4. Right-Click Click on the Clip Function and Remove it. Remove the Colormap Function, as well. Note that your Pasted Layer is now Unclipped and using a Black to White, Stretched Symbology. 5. Right-click click on this Full Extent, Grayscale, NDVI Layer and select Save as Layer File. Save it to the Home Folder der as NDVI.lyr. 6. Remove all but the original NAIP_4_Color_Band_Orthophotogra NAIP_4_Color_Band_Orthophotography1 layer. 7. Return to the Catalog Window and click on the Home Folder to highlight it, and then hit the F5 key to refresh. Drag the NDVI.lyr NDVI.l back into the Map Document.
