Working in point clouds is difficult for three main reasons. This article will help you avoid these common pitfalls and provide a few tips for successfully integrating point clouds into your drone surveying workflow.
Survey conferences from all over the country tend to cluster in the winter months. So, Aerotas bundles up and heads out into the cold to share lessons learned from processing thousands of drone survey projects. While the number of surveyors who use drones continues to grow, there are still a handful of questions that keep cropping up at almost every survey conference. In this article, we will answer the most common questions about drone surveying from this year’s conference season.
The newest version of our checklist is smaller, laminated, and designed to always stay with your drone kit. The checklist will be used along side a paper companion flight log that is now longer so that it can record information about more of your flights. The old checklist was a single piece of paper that combined both the checklist and the flight log; you used a single checklist for each flight. Now, one checklist can be used across multiple flights, and the flight log can hold more information.
Trey Swann from Aerotas presented at The Oklahoma Society of Land Surveyors (OSLS) Convention on Friday, March 1st, 2019. Trey covered the complete field workflow and the complete office workflow for drone surveying. Use this page to download the content from that presentation.

When you use Aerotas to process your drone data, you immediately get access to our Flight Ops team. The sole responsibility of Flight Ops is to guide your mission planning and data collection process. This will ensure that you are successfully planning missions, setting UAS-specific ground control, and getting the most accurate results possible from your drone-collected 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.
