Drone Mapping Accuracy – Part II – Real Time Kinematics (RTK)

January 16, 2017 by Mark Paulson

In an earlier post, we discussed Ground Control Points as a primary method of obtaining survey grade accuracy from drone mapping. The photogrammetry/mapping software (such as Pix4d Pro Mapper) uses these GCP to make adjustments to the project to obtain survey grade accuracy. However, this method requires laying out and precisely geolocating numerous control points (approximately every 1000 to 1500 feet). Depending on the terrain and/or the size of the project, the GCP method could be very impractical, difficult and time consuming. Another, arguably more advanced method, is referred to …

Components for Drone Mapping

January 2, 2017 by Mark Paulson

In this article we cover what’s actually needed – both in terms of hardware and software products, as well as the training and other items necessary to generate UAV mapping products. 1. Drone (UAV) – Fixed Wing or Multirotor Multirotors are a great initial platform – they’re less expensive, easier to fly and the smaller datasets (due to the smaller area covered) are faster to process. A DJI Phantom 3 Advanced or Pro makes a great low-cost starter platform, while a Phantom 4 Pro is not significantly more expensive and …
