Lidar technology for Land Surveying has been around for decades, but technological advancements have now made lidar more accurate, reliable, and affordable than ever before. At Aerotas, we've been processing aerial lidar data for years. In this article, we go through all of the different capabilities and processes necessary to get high quality survey deliverables from your lidar data.
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.
We have processed thousands of drone survey projects for our customers, and we have learned the hard way why photogrammetry is a Ph.D. level science. We have banged our heads against every wall there is, and learned some valuable lessons that we now apply to every project we complete for our customers.
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.
