Out of the Office and Into the Field: Introduction to ArcPad and ArcPad Application Builder A Yale Map Collection GIS Workshop Preparing For the Tutorial 1. Navigate to the C:\Temp folder on your harddrive. 2. Make a New Folder using your initials as the name of the New Folder. For example, if your name is John Jacob Jinglehymer-Smith, you would make a new folder called C:\Temp\JJJ 3. Open the web browser available on your machine and navigate to the Map Collection website at http://www.library.yale.edu/maps. Click on the Download GIS Workshop Materials link under Quicklinks and look for the Out of the Office and Into the Field: Introduction to ArcPad and ArcPad Application Builder materials. Download the Data file to your C:\Temp\intials folder. Unzip the dataset to your initials folder (You should be able to simply right-click on the file and select Extract Here ). This file contains the datasets we will use for the exercises that follow. Preparing the Data for Your ArcPad Application 1. Browse in to the folder that resulted from extracting the Zipfile you downloaded. 2. Double-Click the Yale_Map.mxd map document to Open it. This is the data that you will be exporting to put into your ArcPad Application. What you see now is the base data that provided you reference while performing the survey. This base dataset contains a simple line file which shows features of the built and natural environment on the Yale Campus. It does not, however, contain the information you are interested in, which is where the bike racks are located, and the attributes that apply to them. 1

6. Click OK on the Bike_Racks Form Editing window to apply the changes. 7. Click on the Save Button. 8. Close ArcPad Application Developer. Getting Familiar with ArcPad Now you will open your newly created ArcPad Application in ArcPad. Aside from the screensize, the application will look and operate in the same way it will look and operate on the Windows Handheld device you intend to use it on. One important difference, however, is that you are unlikely to have a GPS unit connected to the desktop that you are working on. This section will demonstrate the collection of data using the Drawing Tools (in this case you will place a point at the location of your bike racks), but the difference between capturing this data manually, or with a GPS point is really only a difference of pressing the capture GPS point button, rather than the Point Drawing button. 1. From the Windows Start menu, launch ArcPad. 2. When Prompted, Browse to the \DataForArcPad1\ Folder and open the arcpad.apm document. 3. Resize the Application Window so that it looks similar to that on the right 4. Use the Drop-Down Arrow on the Zoom Tool to activate the Pan Tool. 5. Pan around until you have duplicated the view in the image on the right. Review the diagram on the next page to quickly familiarize yourself with the tools in ArcPad. Most of the tools are duplicates of those found in ArcMap, so you will already be familiar with how they work. 10
GPS Settings Tools. For setting up GPS Activity in your Application. The Select Edit Layer menu. The Selected Layer will be editable Feature Attribute Tool. Opens the Custom Form, or Attribute Table of a selected feature for editing Capture GPS as Vertices, for creating lines & Polygons Capture GPS as Vertex, for creating Lines & Polygons The Feature Selection Tools, for selecting and editing existing features Capture GPS point, for capturing point data Drawing Tools for Creating New Features. Activate according to the data type of the selected Edit Layer 11
Creating New Features in Your ArcPad Application 1. Using the Select Edit Layer Drop-down, make the Bike_Racks layer the Active Layer. The Editing Toolbar & Drawing Tools should become visible. 2. Using the Drawing Tools Drop-down, make the Point Tool active. The mouse cursor will change to a crosshair. 3. Place a point in front of Sterling Library by clicking once on the map If you were using GPS to capture your features, in this case, you would have simply pressed the Capture GPS Point button. 4. The Bike_Racks form will pop up, ready for you to enter attributes. 5. Populate the attributes of the digitized feature as shown below: 6. Click on the OK icon at the bottom left of the screen. 12
Changing Attributes for a Feature 1. Activate the Select Tool. 2. Click on the feature that you just placed. 3. It will be selected (indicated by a nearly imperceptible dashed bounding box). 4. Click on the Feature Properties button and the form will be presented, with the attributes for the currently selected feature. 5. Alter the attributes as needed and click OK. Deleting Features The easiest means of editing the position of a newly placed feature in ArcPad is to simply delete the feature and replace it. Vertices can be edited for lines and polygons using the Select & Vertex Editing tool. 1. Activate the Select Tool. 2. Click on the Feature that you just placed. 3. Using the Feature Properties Drop-down, select Delete Feature. 13
