Deliverables
Drone surveys can provide a variety of deliverables depending on the specific needs and goals of the project
- Orthomosaic Maps – detailed and geo-referenced map of the surveyed area, providing an accurate representation of the ground.
- Digital Elevation Models (DEM) – 3D representations of the terrain, created by capturing elevation data during the survey. This is valuable for analysing the topography and elevation changes in the surveyed area.
- Digital Surface Models (DSM) – A DSM represents the surface of the Earth, including all natural and man-made features.
- 3D Point Clouds – detailed, three-dimensional representations of the surveyed environment. They are created by collecting data on the location of individual points, allowing for precise measurements and analysis.
- Contour Maps – Contour maps display lines connecting points of equal elevation, providing a visual representation of the landscape’s shape and gradients. This is crucial for construction, land development, and environmental assessments.
- Thermal Imagery – Our drones are equipped with thermal cameras can capture thermal imagery, which is useful for applications such as building inspections, agriculture, and search and rescue operations.
- Vegetation Health Analysis – Multispectral sensors on drones can capture data to assess the health of vegetation. This is commonly used in agriculture for crop health monitoring.
- Volume Calculations – Drones can be employed to calculate volumes of stockpiles, excavations, or other topographical features, providing valuable information for construction and earthwork projects.
- Customised Reporting & Analysis – Customised reports can be generated based on specific project requirements. This may include detailed analysis, comparisons, and recommendations based on the survey data.
- Interactive 3D Models – In addition to static 3D models, some projects may benefit from interactive 3D models that allow users to explore and interact with the surveyed environment in an online virtual space. Measurements and volumes and other analytical capabilities can be recorded in the software. These online models can also be easily shared between team members.

Why Choose Us
How Aerial Surveys are Changing the Industry
Jump on board with the forward thinking companies embracing new technology to obtain meaningful data more efficiently than ever
Safety
Rather than having surveyors on site in dangerous or hazardous areas, we can undertake the operation with zero risk to human life
Due to the lower cost of drone inspections, assets can be inspected more frequently and with higher volume of data is able to be captured minimising the chance of missing something. This leads to identification of dangerous terrain or structures early before they can become a hazard to people
Frequent general aerial surveys on construction sites can spot issues quickly to ensure the safety of people onsite
Cost Efficient
Often what takes days with traditional methods can take hours with drones using less people to conduct the survey.
The equipment used is cheaper than traditional methods and therefore cheaper to hire.
Manned inspections are often associated with enormous insurance costs which are greatly reduced.
Potential work cover claims are also reduced due to the safety of using drones for surveying and 3D Model mapping.
Save Time
A drone can be set up within minutes of being on location and easily navigate around the asset.
No need to set up harnesses,ladders or organise a team to cover large areas.
Also no need to shutdown systems resulting in zero service downtime.
Access
Using rope access , EWP’s or scaffolding has its limits. We can position aerial cameras in the ideal position to enable a high resolution survey of your site or asset.
This gives you a higher quality of data than what would ordinarily be available.
Being able to place drones in these areas so easily without human presence can prevent the need for service interruptions to assets
Survey Data Capture - Trust the Process
High Exposure employs a meticulous step-by-step process for drone survey data acquisition, processing, and visualisation to ensure optimal results and valuable insights for our clients.
Project Planning and Pre-flight Analysis: Before deploying drones, our team conducts thorough project planning, defining survey objectives, and assessing the specific requirements of the area to be surveyed. Pre-flight analysis involves evaluating airspace regulations, weather conditions, and potential obstacles.
Flight Mission Execution: Trained and certified drone pilots execute the flight mission, precisely navigating the drone to capture high-resolution images or videos of the survey area. Advanced sensors and cameras on the drone ensure accurate data collection.
Data Collection: During the flight, the drone collects georeferenced images or videos, capturing the desired data points. The drone’s ability to access hard-to-reach or hazardous areas enhances the comprehensiveness of the survey.
Data Processing and Stitching: Post-flight, acquired data undergoes meticulous processing. Image stitching and georeferencing techniques are applied to create seamless and accurate maps or 3D models. This step ensures the precision of the collected data.
Data Analysis: Processed data is subjected to in-depth analysis, extracting relevant information based on project requirements. This may include topographic features, volumetric measurements, or other specific parameters tailored to the client’s needs.
Integration with GIS (Geographic Information System): The survey data is integrated into GIS platforms, enhancing its spatial context and allowing for a more comprehensive understanding of the surveyed area. GIS integration facilitates effective decision-making by providing a geospatial perspective.
Visualisation and Reporting: High Exposure focuses on delivering insights in a user-friendly format. We create visualisations such as maps, 3D models, and interactive reports, ensuring that our clients can easily interpret and derive meaningful conclusions from the surveyed data.
