Drones have transformed how we capture the world from above. But there’s a key difference between taking a great aerial photo and collecting aerial survey data that can be measured, mapped, and modelled.

In this guide, we’ll explain what aerial photography is, what aerial photogrammetry means, and how to choose the right approach for your project — whether you’re filming content or producing accurate mapping outputs.

Key takeaways

• Aerial photography is about capturing images for visual use (marketing, media, documentation).

• Aerial photogrammetry uses overlapping images to create measurable data like maps, models, and volumes.

• Photogrammetry requires flight planning, consistent overlap, and processing software.

Aerial photography vs aerial photogrammetry: At a glance

Before we delve into the detail, let's take an at-a-glance look at the key differences between aerial photography and aerial photogrammetry.

What is aerial photography with a drone?

Aerial photography is the process of taking photos from above ground level, usually using drones equipped with stabilised cameras.

Most aerial photography is produced for visual impact rather than measurements, meaning the priority is image quality, composition, lighting, and clarity.

Aerial photography has become popular across industries because it delivers a 'big picture' view quickly. Businesses can show locations, properties, and projects in a way that standard ground-level photos cannot.

It’s also one of the fastest ways to capture content for websites, social media, and promotional campaigns.

What is aerial photogrammetry with a drone?

Aerial photogrammetry is a method of capturing many overlapping drone images and converting them into measurable mapping outputs.

Instead of taking one photo designed to look good, photogrammetry captures hundreds of photos designed to be processed by software.

This matters because photogrammetry produces deliverables that support engineering, construction, surveying, and inspection workflows — where accuracy and repeatability are more important than visual creativity.

Photogrammetry is commonly used to create outputs such as:

• Orthomosaic maps.

• Point clouds.

• 3D meshes/models.

• Measurement datasets.

Turning overlapping images into 3D data

Photogrammetry works by identifying common features between overlapping images. When the drone captures a series of images with high overlap, software can match tie points between the photos and reconstruct the 3D structure of the scene.

In simple terms:

• You capture planned images with overlap.

• Software aligns the images.

• The system reconstructs the geometry.

• Outputs are generated for mapping and modelling.

The quality of the final output depends heavily on the quality of the image capture — poor overlap, motion blur, or inconsistent lighting can reduce the accuracy of results.

Drone photogrammetry vs traditional ground surveying

Traditional surveying remains essential for many high-accuracy projects, particularly where legal boundaries or precise control are required.

However, drone photogrammetry adds major value because it can cover large areas quickly and safely.

Compared to ground survey methods, photogrammetry can:

• Reduce time spent walking hazardous sites.

• Minimise disruption to active projects.

• Create visual proof as well as measurements.

• Allow rapid repeat surveys for change detection.

Many professional teams use photogrammetry as a complement to ground surveying, not necessarily a replacement.

When to use aerial photography vs aerial photogrammetry

Choosing the right method depends on your deliverable needs.

If your client wants content that 'looks great', aerial photography is usually the best fit.

If they want data they can measure, compare, and use in planning, photogrammetry is the better option.

Understanding this difference helps drone operators sell the right service — and helps clients get the best outcome for their project.

Visual storytelling and media projects

Aerial photography is the best choice when the job is focused on visuals, storytelling, or marketing.

These projects usually benefit from cinematic camera angles, dynamic movement, and careful editing.

Common aerial photography projects include:

• Property marketing.

• Tourism and hospitality visuals.

• Branded drone reels and ads.

• Event venue promo content.

• Before-and-after visuals for renovations.

For these clients, the value is in the look and feel of the imagery, not measurements.

At this point, and as an aside, XGRIDS reality capture solutions offer a perfect balance: Offering photo-realistic assets, with the ability to conduct measurements.

Measurement and mapping projects

Photogrammetry should be used when you need accurate, repeatable outputs that support decision-making.

Drone photogrammetry is ideal for professional industries where teams need to quantify areas, distances, and changes.

Common photogrammetry projects include:

• Construction site progress mapping

• Land and environmental surveys

• Stockpile measurements

• Infrastructure planning

• Topographic modelling

If the client says 'we need a map we can measure', photogrammetry is likely the correct workflow.

Core concepts for drone photogrammetry surveys

Drone surveys rely on consistent capture and clear technical understanding. Even if you use automated mission tools, it’s important to know what impacts quality and accuracy.

The two biggest concepts most pilots must understand early are GSD (Ground Sample Distance) and image overlap.

Ground Sample Distance and image resolution

GSD describes the real-world size represented by each pixel in an image — usually expressed as a value like cm/pixel.

A lower (smaller) GSD means:

• Higher detail.

• Higher accuracy potential.

• More images required.

• Larger file sizes.

• Longer processing time.

Higher GSD (less detail) can still work for progress tracking or large-scale mapping, but it may not be suitable for projects needing fine measurements.

For more information on GSD, read our detailed Guide to GSD blog.

To calculate optimal GSD, use our GSD calculator tool.

Image overlap and flight planning

Photogrammetry relies on overlap because it needs multiple viewpoints of the same features. Without overlap, software can’t align images reliably.

Overlap planning affects:

• Dataset quality.

• Processing success rate.

• Model completeness.

• Edge sharpness and distortion control.

Even small mistakes like flying too fast, using the wrong shutter speed, or capturing inconsistent lighting can cause issues — which is why survey planning is a major part of professional drone workflows.

Drones and payloads for aerial imaging

Not every drone is built for the same job. Photography drones prioritise image aesthetics and cinematic movement, while survey drones prioritise stable capture, repeatability, and consistent flight planning.

Selecting the right drone depends on your industry and deliverables.

Camera drones for photography

Camera drones are designed to produce visually appealing images and smooth video. They’re ideal for marketing, content creation, and documentation.

Benefits of photography drones include:

• Stabilised gimbals for clean footage.

• Strong video modes and profiles.

• Fast setup and deployment.

• Easy workflow from flight to edit.

For most 'visual content' businesses, a strong camera drone is enough to start earning quickly.
