How Aerotas Processes Drone Data
Aerotas provides human-in-the-loop data processing services for professional land surveyors and civil engineers throughout the United States. 800+ high-performing surveyors use Aerotas to process drone-collected data.
With Aerotas, you get to skip the photogrammetry and data extraction steps and go straight from flying the drone to finishing up in CAD.
You choose the right deliverable for your project
Aerotas pricing is quote-based for each project, and you can request a quote for free.
Proprietary workflow and the right high-performance computing architecture
Aerotas has invested in infrastructure – including high-performance computing architecture and a first-class team of ASPRS Certified Photogrammetrists and CAD Technicians – enabling us to deliver survey-grade deliverables in days, not weeks.
Aerotas has developed a proprietary workflow to process data in the most accurate way possible. The key to our workflow is our trained professionals involved at every step.
Human-in-the-loop at every step
ASPRS certified photogrammetrists
Multiple steps of quality assurance
Data team based in the U.S.
Once you upload your data, our ASPRS Certified Photogrammetrists produce a rich 3D model of your project and develop a preliminary accuracy profile. At Aerotas, every project goes through multiple rounds of processing to properly manage camera calibration, ground control, project cohesion, and a host of other things.
If the Aerotas Data Team identifies an error, we reach out to you immediately to ensure that you only receive the highest quality data. If the error is greater than 0.1' vertical, then we do not deliver without speaking with you first.
Examples of errors addressed in photogrammetry
Movement of ground targets
Variable altitude projects
Malfunctioning ground equipment
Coordinate system mismatch
Professionally drafted linework created from your drone data
Once our photogrammetrists have finished creating the rich 3D model, our team of CAD drafters and technicians get to work extracting only the data you need. We use a suite of different 3D modeling and CAD programs to deliver on-time and on-budget, in the most accurate and efficient way possible.
Linework drafting is necessary because the outputs of photogrammetry are too big for CAD. There is just too much data that you do not need, and not enough data that you do need. Plus, automated contours face challenges, and Aerotas likes to perform an intentional selection of the critical points and lines that we export to CAD. This method is preferable to a “dumb” decimation of the point cloud.
Photogrammetry and drafting services grounded in end-to-end quality
No matter which service you choose, you’ll always get the same convenience, accuracy, and quality from Aerotas’ deliverables. When you upload data to Aerotas, you can rest assured that your data is being handled by ASPRS Certified Photogrammetrists and CAD Technicians here in the U.S.
We hold ourselves to the highest photogrammetry industry standards. In this case, our guiding document is the ASPRS Positional Accuracy Standards for Digital Geospatial Data; the same standards that are used for manned aerial photogrammetry with larger, metrically calibrated cameras.
No need to trust cloud-based automated services or software quality reports, with Aerotas you can be confident in the data because there is a human-in-the-loop correcting error and performing quality assurance checks at each step in the data processing workflow.

What you get from Aerotas
Aerotas can deliver your basic photogrammetry deliverables (Orthophoto, DSM, and a Point Cloud), a manually drafted clean TIN surface with spot elevation points, breaklines, and 1’ contours, or full linework that includes all planimetric features that are visible from the air.
Linework Deliverables (DWG):
Spot Elevation Points
World File (TFW)
Point Cloud (LAS)
Flexible pay-as-you-go pricing
Aerotas creates quotes for each project based on that individual project’s size, complexity, and the features requested.
