  1. Trimble GeoXM A Platform For ArcPad and PedonCE Use of a PDA/GPS on the Spokane County Soil Survey

  2. Spokane Soil Survey • Update of 1968 Soil Survey • Mapping consists of range land, Ag land, and forested areas • All line work completed in ArcGIS • Entering final field season

  3. Trimble GeoXM • Mobile PC • Ruggedized PDA/GPS unit • Has Bluetooth capabilities • Supports ArcPad and PedonCE • Communicates with PC allowing for transfer of data from Trimble to PC

  4. ArcPad 7.0 • Mobile ArcGIS • Looks and acts similarly to ArcGIS • Has less functionality than ArcGIS • Allows for viewing of some raster files and all shapefiles in the field • Allows for editing of shapefiles in the field

  5. Use On Our Survey • ArcPad • Transfer shapefiles and some rasters from PC to PDA for viewing in the field • Common files we use: • DOQ imagery • Hillshades • 1968 soil lines • Update soil lines • GPS points • Road maps • Ownership maps

  6. Adding Data

  7. Viewing Editing

  8. Personalization

  9. Movement Data Manipulation Labeling Transparency

  10. ArcPad 7.0 cont. • In the field: • View exactly where you are on your map • Watch yourself walk across your map • Create new shapefiles • Polygons, polylines, and points • Edit new and existing files • Take GPS points • Add attribute information to GPS points

  11. Shapefile Delineation • In the field: • Delineate the landscape • Hand drawn • Add Vertices • Freehand line or polygon • Take points at set intervals while walking • Manually take points while walking • Shapefiles are easily transferred to ArcMap

  12. Draw by Hand on PDA screen

  13. Points At Staggered Intervals

  14. PedonCE • USDA-NRCS developed software • Uses Microsoft Access databases for domains • Allows for soil descriptions to be recorded on the PDA • Removes manual data entry into NASIS

  15. PedonCE cont. • Will use this coming field season • Will create two sets of databases • Dumbed down for field notes • Full for 232’s

  16. Positives • See where you are on your map • Ruggedized • Digitally delineate the landscape in the field • Take GPS points with attribute information • Record field notes and 232’s in the PDA/GPS.

  17. Drawbacks • Can struggle with taking GPS points in densely treed landscapes • Newer GeoXM units have Windows Mobile 5.0 • Access databases will not transfer from PC to PDA with 5.0 • PedonCE will not work

  18. Conclusions • Excellent tool for identifying exact location • Works well in range areas, agricultural, and thinly treed landscapes • We look forward to utilizing PedonCE this summer
