How Photogrammetry Works

Photogrammetry utilizes the principal parallax to calculate locations and elevations of real-world features. Like our eyes, people can get a sense of distance because we are observing an object from two different locations (each of our two eyes). Spitfire Drone Survey capitalizes on this principle by mounting a camera on a drone and taking multiple overlapping photos of the region or features of interest. These photos can be imported into processing softwares, along with survey grade GPS observations to calculate accurate point clouds, models and orthomosaics.

A Complete Solution

Our Digital Toolkit

Photos are acquired such that there is sufficient overlap between photos. Required amount of overlap varies depending on characteristics of the site, but typical overlap for basic sites is 75% forward and side overlap. Once photos have been collected, they are inputted into an aerial triangulation software where images and ground control are tied together to calculate point clouds, orthophotos and DTMs.
The result of these technologies is an unbeatable combination of resolution, flexibility and usability. Our customers use this data to save money, improve quality and drive efficiency in their businesses. Ready to start working together?

Construction Project Management

Progress Monitoring at Area 6

Our Process

1

Preparation

We start by understanding your project needs and target output. We will review the location to ensure safe and legal flight and verify any regulatory requirements.

2

Scanning

We will arrange to be on site at the optimal times during your project to capture the initial scan and subsequent progress update. Our team of certified and insured pilots will ensure minimal disruption to site activity.  

3

Data Processing

After the flight, we process and data and prepare it for your use. We provide the appropriate file types and formatting to fit your workflow.

4

Quality Assessment

Independent measurements collected from traditional survey techniques are compared to our processed product to confirm our data is accurate.

5

Deliverable Generation

Using our product from the data processing, we generate deliverables catering to our clients’ individual needs, including digital terrain models, grading plans, earthworks reports, monitoring reports, various point cloud classifications, 3D design overlay and integration of high precision total station/survey grade GPS measurements with aerial survey data.

What Our Customers Say

"

"Spitfire delivers data that is responsive to our needs and catered to our workflow as an architecture firm, capturing what traditional surveys miss and enabling us to effectively site our projects to suit any given context."

“We recently chose to have Spitfire Drone Survey look after all of our project completion quantity verifications.We have been thrilled with the services they offer, they are fast, professional and provide quality end products that we are happy to share with our customers.To top it all off they provide their services at a very reasonable price. I would highly recommend their services, the finished results exceeded our expectations.”

"The data is absolutely fantastic. Comparing to the “original” high-altitude lidar, it’s now obvious that it was smoothed pretty aggressively, and your data gives us the real shape of that canyon."
