On 10/10, DJI announced the Zenmuse L2. We believe the new L2 will offer exceptional technical improvements over both the L1 and the current mid-tier sensor market. We’re excited to share what we know about the delivery timeline, and how we view the technical specs.
DJI’s long-anticipated L1 sensor is finally here, and we’ve been doing dozens of test flights and spending hundreds of hours flying and analyzing data to create a real-world, field-tested review of the newest DJI L1 sensor.
DJI states that “The P1 supports 24mm, 35mm, and 50mm lenses with industry-specific DL mounts. Only use lenses engraved with the "DJI Enterprise" logo to produce survey-grade accurate results.” But, there is more to the story.
There are numerous ways to process GNSS data from the DJI M300 RTK and the Phantom 4 RTK. This article will discuss the five most common methods for processing data from DJI RTK drones and weigh their strengths and weaknesses.
Read the article to get answers to these common questions:
Can I use my Trimble, Leica, or Topcon base with the Phantom 4 RTK?
Is it possible to use my NTRIP correction service without a base station?
Will the DJI D-RTK 2 work as a standalone base or rover?
Terrain awareness, or terrain-following as some like to call it, eliminates the variance in above-ground flight height and thus eliminates the discrepancies in overlap throughout sites with high topographic relief. Consistent overlap leads to more reliable data overall, and Terrain Awareness guarantees more consistent overlap.
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.
