  1. NSF DUE-0903270 Introduction to ArcPad Prepared by: Jennifer McKee With support from: in partnership with: Geospatial Technician Education Through Virginia’s Community Colleges (GTEVCC)

  2. Mobile GIS • Allows field staff to capture, update, analyze spatial data • 3 Types of Mobile GIS currently • ArcGIS Mobile • For enterprise field-workers, medium to large organizations, deployed from ArcGIS Server, taskcentric workflow • ArcPad • For GIS managers and field-workers, small to medium organizations, deployed from ArcGIS Desktop, mapcentric workflow • ArcGIS for iPhone

  3. ArcPad • A Mobile GIS product allowing for field data collection & mapping, GPS integration, and database access using wireless technology • Can be run on any mobile device that runs Windows Mobile OS

  4. Windows Mobile • ArcPad is only compatible with the following Windows Mobile operating systems: • ArcPad 8 - WM OS 5.0, 6.0, 6.1, or 6.5 • ArcPad 7.x - WM 2003, 5.0, 6.0, 6.1, or 6.5 • Windows Mobile supports • Microsoft Office mobile (Excel, Word, PowerPoint) • Microsoft Office Outlook Mobile • Internet Explorer Mobile • Microsoft Office Communicator Mobile & more • Most mobile devices come with either Windows Mobile or Palm O.S.

  5. Microsoft ActiveSync • Synchronization software for PDAs • Easy way to connect PDA to computer and transfer information, settings, & files • Synchronization software depends on OS of computer • Windows XP or earlier – ActiveSync 4.5 • Windows Vista or Windows 7 – Windows Mobile Device Center • If not currently installed, is a free download from Microsoft http://www.microsoft.com/windowsmobile/en-us/downloads/microsoft/activesync-download.mspx

  6. ArcPad Benefits • Collect & validate field data • Incorporate rangefinders, GPS, digital cameras & barcode readers into data collection • Enterprise data can be shared with field workers & updated • Increase efficiency of field data collection

  7. Example Applications • Health and Human Services • Mosquito Control Field Inspection template • Infrastructure & Utilities • Storm water management • Natural Resources • Agriculture and Natural Resources tools • Public Safety • Fire perimeter mapping • State & Local government • Equipment & inventory maintenance • Urban & Regional Planning • Parks Inventory Templates available from ESRI at http://resources.arcgis.com/content/mobile-gis

  8. ArcPad files • Usual shapefile & raster extensions (not all raster types supported, i.e. .img) • .dbf, .shp, .sbx, .prj, .sbn, .shx, etc • Uses additional files: • .apm – map document • .apl – layer definition file • Can customize creating forms associated with a specific shapefile • .apx – configuration file • Used to alter the basic ArcPad configuration • .apa – applets that can run within ArcPad Typical files you will see/use Seen more often with custom applications

  9. Interface Main toolbar Browse toolbar Edit toolbar Scalebar Status bar Command bar

  10. Drop down menus Any icon with a has a drop down menu 1 2 3 4 1 2 3 4 5 6 7 8 9 10 5 6 7 8 9 10

  11. Explore Data - Table of Contents • Select (TOC button) • Check under • allows you to see layer • allows you to ID the layer • makes layer editable • Highlight layer & select to see layer properties

  12. Explore Data - Table of Contents • Choose map projection definition file • Map properties • Add data • Layer properties • Rearrange layers • Remove layer 1 2 3 4 5 6

  13. Layer Properties • Tabs: Information, Labels, Symbology, Scale, Hyperlink, Attributes, Transparency, Geography • What can be changed/set: • Labels • Symbology • Scale • Hyperlink fields • Transparency To Close ArcPad – File menu > Exit *** if you use the X in the upper right corner, ArcPad is STILL running

  14. Exercise Overview • We will export data from ArcMap to ArcPad • Build custom form in ArcPad Studio • Transfer data to PDA • Create new shapefile in field • Collect data • Transfer collected data to desktop

  15. Exercise Details • We will be collecting data 2 ways • Using a customized form • Create shapefile in ArcPad • Use infrastrature.shp with form to collect information on location, type, condition, and maintenance needs • Type = Benches, Lamp, Sign, Trash Can • Condition = Good, Fair, Poor • Maintenance needs = free text field • Create shapefile to collect tree size • Size = Small, Medium, Large

  16. Data Preparation • ALL data used for an ArcPad project MUST be in the same projection • ArcPad toolbar Get Data for ArcPad Undo Check Out Check in Edits

  17. Data Preparation • Open VT.mxd (located C:\data\Arcpad\) in ArcMap • Explore data • 1 imagery file (2005 Blacksburg ) • Roads • Zoom in/out until the parking lot southwest of Cheatham Hall is in view (10923006.311, 3610590.736 feet) and scale is 1:1500

  18. Let’s start the exercise! Exporting data for ArcPad • Click “Get Data for ArcPad” button • Select layers to be exported • Select spatial extent (current display), Specified features, Output folder name (ArcPad_VT), & Location (c:\data) • Review completed export report 2 3 4

  19. Creating a custom form • Open ArcPad Studio • Start> All Programs> ArcGIS> ArcPad 8.0> ArcPad Studio • When asked “Start using ArcPad Studio with a” • Choose – “New layer definition project” > Click OK • Navigate to ArcPad_VT folder & select Infrastructure.shp > click Open • When asked if you want to replace an existing form, click Yes

  20. ArcPad Studio: Form Wizard • Layout tab • Caption = Infrastructure • From drop down menu select “¼ VGA – 240x320 (Pocket PC)” • Check: Attributes Page

  21. ArcPad Studio: Form Wizard cont. • Fields tab • Make sure all fields are checked (ID, TYPE, CONDITION, & MAINT_NEED)

  22. ArcPad Studio: Form Wizard cont. • Controls tab • Required column • Check Id, Type, & Condition • Id row • Minimum = 1 • Type row • List values = Benches, Lamp, Sign, Trash Can • Condition row • List values = Good, Fair, Poor • Click OK

  23. More Form Alterations • Double click on <EDITFORM> Infrastructure • Double click on white box next to Id • When Control Properties window opens, select Values tab • Minimum Value = 1 • Check “Auto Increment” 2 1 3

  24. More Form Alterations • This is what your custom form will look like on the PDA • Click OK & SAVE the form – Close ArcPad Studio

  25. Transferring Data to PDA • Connect PDA to laptop • When asked the “Synchronization Setup Wizard” dialog opens, cancel out of it • Microsoft ActiveSync dialog will open • Click Explore on ActiveSync interface, a new window will open • Open a Windows Explorer on your desktop & navigate to C:\data\ • Copy ArcPad_VT folder to PDA • Close both windows when copy & convert is finished 4

  26. 1 Using the PDAs 2 • If not on, Turn PDA on by pressing down &holding the power button • Select Start > ArcPad 7.0.1 • Open ArcPad.apm within the ArcPad_VT folder • Click OK 3 4

  27. Create new shapefile 1 & 2 • Select drop down arrow next to the open button • Select New > Shapefile • Type = Point • Click + button • Name = Size • Select Text • Select OK 3 4

  28. Create new shapefile cont. • Click OK • When prompted enter the following • Name = Tree • Folder = ArcPad_VT • Type = Shapefiles • Location = Main memory • Click OK

  29. Creating QuickForm • Layout tab • Select Attributes Page • Controls tab • Required column • Check SIZE • List Values column • Small, Medium, Large • Click OK 1 2 3

  30. Collect data • Select the edit menu button & select either Tree or Infrastructure to edit • Collect at least 5 features for each shapefile

  31. Create a point • Zoom in • On the Edit toolbar, select the point feature tool • Touch the screen where you want to locate the point • Or Turn the GPS on, click (GPS drop down menu) & select GPS Active • When the GPS determines your locations, put a point where the GPS cursor is

  32. Transferring Data to Computer • Once all data points have been collected, select the Save button & shut down ArcPad (file menu > exit) • Connect PDA to computer • Cancel out of the “Synchronization Setup Wizard” dialog • Click Explore on ActiveSync window • Copy data in ArcPad_VT folder from PDA to C:\data\Arcpad\ • Now VT.mxd can be reopened & data examined • Add your Tree shapefile to the map document

  33. Any Questions? • Just remember.. • ArcPad can be put on ANY mobile device that runs Windows Mobile (field computer, PDA, tablet PC, etc) • Practice makes perfect Jennifer McKee Geospatial Project Developer jmckee@vt.edu (540) 231-9115 www.gep.frec.vt.edu
