  1. July 14, 2011 GeoCollector for ArcPad A High Accuracy Field Mapping Solution Andrei Link (Trimble) Rui Ge (Esri)

  2. Overview • Why accuracy matters • What is GeoCollector • GeoCollector workflows • Steps in a typical project • Field data collection – best practices • Real-time and post-processed differential correction • Demo using ArcGIS and GPS Analyst • Returning data to the enterprise - best practices

  3. Why high accuracy matters • Pipeline integrity management • Water network modeling • Weed management • Delineation mapping • Transmission line optimization • Corridor mapping • Land valuation

  4. GeoCollector – High Accuracy GPS solution GPS correct GPS Analyst • Trimble GeoExplorer 6000 series device • High productivity hardware platform • High accuracy GPS data: 10 cm (XH) or 50 cm (XT) • Esri ArcPad data collection software • Seamless integration with other Esri products • Trimble GPSCorrect for ArcPad software • GNSS receiver control; data collection for postprocessing • Trimble GPS Analyst extension (option) • Differential correction directly in ArcGIS for Desktop • Support through Esri, hardware+software warranty

  5. GeoCollector Workflow (Full) Mobile Server Desktop Desktop Server Export to Personal Geodatabase GPS Analyst Check out Copy to device Copy to Desktop GPS Analyst Check In Post process Import to Enterprise Data validation ArcPad GPScorrect Enterprise Geodatabase

  6. GeoCollector Workflow (local data only) Mobile Desktop Desktop Copy to Desktop GPS Analyst Check In Post process GPS Analyst Check out Copy to device ArcPad GPScorrect

  7. GeoCollector Workflow (no prepared data) Mobile Desktop Copy to Desktop Post process with Toolbox QuickProject GPScorrect

  8. Seven steps of a successful project • Define project goals • Prepare your data • Send data to the device • Configure field settings • Collect or update data • Receive the data • Process the data

  9. Real-time differential correction Accuracy in the field Good for navigation/in-field verification Up to 10cm in real-time with GeoXH Saves time in the office Correction broadcast WAAS DGPS Beacon Virtual reference station (VRS) Correction receiver Integrated WAAS in GeoCollector

  10. Post-processed differential correction Accuracy in the GIS Up to 10cm with GeoXH and H-Star technology Overcomes broadcast outage in the field Can alter processing settings to improve data Base station logging data Internet access List maintained in GPS Analyst GPS Analyst Post processing engine

  11. Check in and GPS Differential Correction Demo

  12. Returning data to Enterprise • You return your processed data to the enterprise • If you have topology rules in enterprise, run data validation on returned data • Only the features with their corrected GPS coordinates are returned. NOT all the raw GPS data.

  13. Summary GPS correct • ArcPad is interface for collecting features • GPScorrect sets up real-time GPS and quality settings andstores the GPS measurement information used to collect the feature geometry • GPS Analyst provides differential correction and GDB integration provided by tools in GPS Analyst • Differential correction enables the accuracy specification for the GeoExplorer! GPS Analyst
