Aerotas has been successfully processing data collected with the Phantom 4 RTK since October of 2018. When working with Aerotas, this is the recommended workflow for PPK processing.
Airborne RTK for land surveyors has been a technology with an enormous amount of promise for quite a few years now, but was being held back by extremely expensive, complicated, and unreliable technology. However, with the recent announcement of the DJI Phantom 4 RTK, it seems as if this is about to change. Overall, the Phantom 4 RTK is a great piece of technology that will improve both accuracy and efficiency for most surveyors, but it is not a magic bullet. Good operations are required both in the field and in post-processing the data.
When the American Society of Photogrammetry and Remote Sensing (ASPRS) launched their Certified Mapping Scientist-UAS certification, Aerotas Founder Logan Campbell was among the first people to sit for the test. The intensive experience of studying, preparing, and taking the strenuous exam highlighted how challenging a verifiable understanding of photogrammetry is. However, the real-world experiences that Logan and the Aerotas team have with processing drone data for surveyors reveal the importance of this understanding in the real world.
With Aerotas' position as the preeminent provider of drone solutions for land surveyors, we constantly field questions from surveyors about various components of drone technology. This is the third in a three-part series of articles in Point of Beginning magazine, summarizing our current analysis on key components of drone survey technology. This article focuses on the georeferencing options we most commonly get questions about -- particularly high-accuracy RTK, PPK, or Direct Georeferencing systems.

Last week, the California Land Surveyors Association invited Aerotas co-founder Daniel Katz to present a webinar to their members on best practices in drone surveying. With the experience from training and equipping several hundred surveyors nationwide to get best-in-class accuracy and ROI from drone technology, and completing thousands of drone photogrammetry and linework drafting projects, the Aerotas team has learned a great deal about what it takes to benefit from drone technology.
Point of Beginning magazine asked Aerotas co-founders Daniel Katz and Logan Campbell to analyze the various components of drone technology that go into an effective drone survey program. They evaluated three key technologies across three articles: drone airframes, sensors, and georeferencing options. In each article they take an independent and analytical approach to evaluate which drone technology option is best for land surveyors. The first article focuses on drone airframes.
