Hawaii Pacific GIS Conference 2012: Survey and Positioning - GNSS (GPS) Workflows with Integrations to GIS

  1. 1. MODULE 1GNSS (GPS) Workflow and Integration into GIS Karyn Nolan
  2. 2. Top 3 Questions What is the accuracy of the equipment? How do I have a picture as an attribute? Why is my data in the ocean? ….other tips along the way
  3. 3. Differential CorrectionsReal Time Accuracy Autonomous – 10 m with uncorrected GPS Satellite Based Augmentation System (SBAS) – 1-5 m – WAAS - US – EGNOS - Europe – MSAS – Japan – GAGAN - India
  4. 4. VRS - Difference in Accuracybetween traditional RTK and VRS
  5. 5. Future Trend Real Time Accuracy VRS subscription or Single Base broadcast – cell phone or radio – http://www.trimble.com/infrastructure/services.aspx 100cm VBS/WAAS/EGNOS 15cm XP/G2 10cm HP 4cm CenterPoint RTX 2cm RTK/VRS 0cm
