Aerial Surveys

Aerial surveys have played a significant role in the field of surveying and cartography for many years. The origins of capturing images from the sky can be traced back to 1858 when French photographer Gaspard-Felix Tournachon took aerial photographs of Paris using a hot air balloon. In 1882, British meteorologist E.D. Archibald pioneered the concept of unmanned aerial surveying by capturing aerial images with a camera attached to a kite.

The 20th century marked a turning point in using aerial imagery for mapping purposes. Technological advancements allowed for the capture of high-resolution images and videos, which could be stitched together and analyzed using Photogrammetry to extract elevation data. However, the complexity and cost of this technology limited its use to large corporations, entities, and governments. This situation changed with the introduction of more powerful and portable computers, digital photogrammetry techniques, and drone technology. These technological leaps made aerial surveying and mapping accessible to a broader audience at an affordable price.

At Strydom and Associates, we have been conducting our own aerial surveys since 2010 when our founder, Herman Strydom, witnessed the technology on display at a surveying conference in Europe. Our initial drones were locally manufactured in Namibia and served us well for three years before we upgraded to more advanced models to keep up with evolving technology. During this time, we also expanded our aerial survey operations by acquiring manned aircraft, starting with the Jabiru J430 and later adding the Sling 4, both of which allowed us to conduct larger-scale surveys
To effectively meet the diverse needs of our clients, we now possess a range of aerial surveying platforms, including:
