Advanced aerial surveying solutions for accurate, efficient, and comprehensive data collection.
What is Aerial Surveying?
We provide aerial surveying and mapping services across Melbourne and Victoria, with survey-grade accuracy.
Aerial surveying encompasses the process of gathering data from airborne platforms like unmanned aerial vehicles (UAVs). This data collection utilises a range of high-definition instruments, including photogrammetry.
UAVs are transforming the field of professional surveying by making what was once a time-consuming, expensive, and challenging task more efficient. These advanced aerial devices are specifically designed to produce high-resolution survey data. They can capture detailed aerial imagery and, through photogrammetry, convert it into accurate 3D models and Aerial Mapping deliverables with centimeter-level precision.
From Melbourne CBD road projects to rural Victoria subdivisions, our drone surveys deliver accurate orthophotos and terrain models.

FAQs
FREQUENTLY ASKED QUESTIONS
Answer:
Weather Dependence: Aerial surveys are highly dependent on weather conditions. Cloud cover, rain, fog, and high winds can all interfere with data collection, leading to delays or inaccurate results.
Resolution Limitations: While aerial surveys can cover large areas, the resolution of the data might not be as high as ground-based surveys. This can be a limitation for projects requiring extremely detailed measurements.
Regulatory Restrictions: There are various regulations governing airspace, particularly in urban areas, near airports, or over sensitive sites. These regulations can limit where and when aerial surveys can be conducted.
Interference from Obstacles: Tall buildings, trees, or other structures can obstruct the view, leading to incomplete data capture or the need for additional flights to cover the area effectively.
Answer:
Advanced Sensors: Utilising high-resolution cameras to capture detailed and accurate data.
Reference Points: Placing accurately surveyed ground control points (GCPs) in the survey area. These points serve as references for georeferencing aerial images, helping to correct any positional inaccuracies.
Forward Overlap and Side Overlap: Ensuring adequate forward overlap and side overlap between images to facilitate accurate stitching and reduce errors.
Answer: The Ground Control Points (GCPs) are marked and surveyed with high accuracy, often using GPS or other geodetic methods. In aerial surveying, GCPs play a critical role in ensuring the accuracy and reliability of the data collected.
Answer:
Photogrammetry
- Photogrammetry involves capturing a series of overlapping photographs from an aerial platform (such as a drone, airplane, or satellite) and using software to analyse and interpret the images.
- The process relies on identifying common points in multiple images taken from different angles to create 3D models and maps. These points are used to calculate distances and elevations, essentially using geometry to reconstruct the 3D space.
LiDAR (Light Detection and Ranging)
- LiDAR uses laser pulses emitted from a sensor on an aerial platform to measure distances to the Earth's surface. The sensor measures the time it takes for each pulse to bounce back, calculating the distance based on the speed of light.
- The result is a dense 3D point cloud representing the surface and objects, including buildings, vegetation, and terrain.
Answer: Weather conditions significantly impact the quality and feasibility of aerial surveying. Factors like cloud cover, rain, wind, fog, and lighting can all influence the data collected.
Cloud Cover: Clouds can obstruct the view of the ground, leading to incomplete or unusable images. Shadows from clouds can create inconsistencies in the data, making it difficult to stitch images together accurately.
Rain: Rain can blur images, distort colors, and create reflections or glare on surfaces, all of which reduce the quality of the photogrammetric data. It can also damage cameras and other equipment.
Wind: Wind can cause the aerial platform (e.g., drone) to move, leading to motion blur in the captured images. This can reduce the sharpness and alignment of images, making it challenging to create accurate 3D models or maps.
