Webinar Replay: Little-Known Nuances of Drone Mapping & Recommended Workflow, Importance of GCP's and Pros & Cons of Different Types of GPS

Originally Aired: Tuesday, Sep 9, 2019, at 6 pm EST In today's webinar, Angad and Eric join Paul to reveal some little known nuances of drone mapping. We talk at length about the different types of GPS - RTK, PPK, NRTK, and PPP and recommend the best option for you. Further, we also talk about best practices for marking GCP's to get the most accurate mapping data possible. We also answer questions from our listeners and attempt to address some common paints. Whether you are an established mapping professional or aspiring to be one, this is a webinar that you do not want to miss. Tune in now!

  • [11:33] Can you mark GCP's with your cellphone?
  • [12:50] What are the different types of GPS?
  • [13:16] I am curious about your choice of Leica vs. Trimble as I am ready to buy a Rover and want one that is industry standard. Can you talk about that?
  • [14:25] Are there any reliable Chinese made GPS units?
  • [16:28] What is a static receiver?
  • [17:42] Angad explains how you can eliminate error using a GPS unit
  • [18:26] Is a static receiver a PPK receiver? Why do surveyors avoid using PPK technology?
  • [19:25] Single frequency vs. multi-frequency GPS Understanding the difference
  • [20:32] What is GPS L5 frequency?
