Aerial Photogrammetry Surveying

What is Aerial Photogrammetry?

Aerial photogrammetry surveying is a method of capturing images from drones or aircraft to create accurate maps, 3D models, and measurements of the Earth’s surface. It uses overlapping photos and software to generate detailed spatial data without physical contact.

In Malaysia, this technique is widely used in construction, land development, agriculture, mining, and environmental monitoring. It provides fast and cost-effective data collection, especially in large or hard-to-reach areas.

At Geotechnica, we offer professional aerial photogrammetry services using high-resolution drone cameras and mapping software—helping clients make better decisions with clear visuals and precise ground information.

FAQ

Aerial Photogrammetry FAQ

What is aerial photogrammetry surveying?

It’s a method of using drones or aircraft to capture overlapping images and generate accurate maps, 3D models, and measurements of the ground surface.

How does drone photogrammetry work?

A drone flies over the site, takes high-resolution photos from above, and specialized software stitches the images into orthophotos and 3D models.

What are the benefits of aerial photogrammetry in Malaysia?

It’s fast, cost-effective, and ideal for large or hard-to-access areas—especially useful in construction, agriculture, disaster zones, and land planning.

What industries use aerial photogrammetry services?

Industries like construction, mining, agriculture, forestry, urban planning, and environmental monitoring benefit from drone-based mapping.

Can aerial photogrammetry be used for topographic mapping?

Yes. It can generate detailed topographic data including contours, Digital Elevation Models (DEM), and surface profiles for engineering projects.

What’s the difference between LiDAR and photogrammetry?

LiDAR uses laser pulses for mapping, while photogrammetry uses images. Photogrammetry is more cost-effective for visible features, but LiDAR performs better in dense vegetation.

Is aerial photogrammetry accurate enough for surveying?

Yes. When properly planned with ground control points, it can achieve high accuracy suitable for engineering, planning, and boundary mapping.

Can drone mapping help with agriculture monitoring?

Absolutely. Aerial surveys can detect crop health, irrigation issues, and growth variations using vegetation indices like NDVI.

Is aerial photogrammetry useful during disasters?

Yes. It allows rapid post-disaster assessment by mapping damage areas, monitoring landslides, and helping emergency teams visualize the situation.

Why choose Geotechnica for aerial photogrammetry in Malaysia?

Geotechnica combines drone technology, expert analysis, and GIS integration to deliver accurate aerial mapping services tailored for Malaysian terrain and projects.
