1. Using the iPAQ Pocket PC to Record Measurement Metadata For Field Instruments June 28, 2004 by Kenneth Smith

2. Introduction The model of pocket PC being used is the Compaq iPAQ H3670. Has a touch screen and a stylus to write with. Expansion pack includes a 256 MB compact flash card and an external battery. Software includes pocketWord, pocketExcel, and ArcPad 6.03.

3. Introduction ArcPad is the GIS software for the handheld device. It operates like a stripped down version of ArcView. Allows you to use a base map or aerial photo of your location, and take waypoints by either selecting a location on the map, or by using a GPS unit. The ArcPad software has been customized to allow the user to easily enter metadata information for each ASD and the D&P.

4. Basic Theory Information that will be recorded will pertain to both the subject being measured as well as the actual measurement itself (including instrument specifications). The information in ArcPad is stored in a shapefile. This is a vector file that includes geographic feature information and metadata for the measurements 1. The shapefile has associated.SHP,.SHX, and.DBF files. 1 Clarke, Shane, Craig Greenwald, and Valerie Spalding. 2000. Using ArcPad: ArcPad 6. ESRI. Redlands, CA

5. GPS Use By connecting a GPS unit to the iPAQ, you are able to see where you are on the map. Waypoints are saved to the shapefile, so that the points do not have to be saved to the GPS unit. The GPS acts as an antennae.

6. Creating a Shapefile Create a new layer under the file menu Choose to create a point shapefile You can either manually add data fields, or import the from a template spreadsheet The shapefile should be named based on the date such as 20040614.shp

7. Using ArcPad Open Instrument Form Takes a GPS Waypoint Takes a Map Point Metadata Form Adds Layer to Map Subject Location Points

8. Using ArcPad After filling out the information for the measurement subject, you are given the choice of which instrument you are using. The rest of the metadata is specific to the instrument being used.

9. Removing Data from the Storage Card The shapefile and DBF files of subject and mesurement information are transferred to a PC via a card reader The information on the DBF files can than be uploaded to the Measurements Website after it is reviewed
