 MAPPING, MINING & ENVIRONMENTAL SURVEYS 

Utilising specialised UAV's, we are able to provide a revolutionary way to map out locations for our clients in a safe and accurate manner in the provision of a high-resolution aerial survey and spatial solutions. Working as a seamlessly integrated team, we understand the need for reliable, timely survey data to enhance productivity or for determining precise geographical location.

 

Capital Remote Aviation Pty Ltd Surveys are a cost-effective alternative to conventional aerial surveys as well as mapping, so whether it be simple oblique photography, complete or more complex 3D modelling required, we will capture and process your data accurately, efficiently and cost-effectively.

 

UAV’s with collision protection, active camera stabilisation that are GPS assisted are proving themselves invaluable tools in allowing surveyors to collect accurate spatial data from above means fewer man-hours are required to produce large, accurate data sets, boosting productivity. Surveying projects that once took days or weeks using traditional surveying techniques are now possible in just a few hours.

 

Our Pilots and UAV’s ability to collect data from above, the downtime associated with surveyors moving around, using terrestrial surveying instruments is eliminated. Drone-based data collection improves safety by vastly reducing the time specialist workers spend on site.

 

During and post-flight, footage can be processed through specialist software tools to produce Ortho-mosaics, digital surface models and three-dimensional representations of the area to be surveyed, which can then be viewed and annotated, without the need for specialist software on the customer side.

Engineers can use this data to measure distances (m), areas (m2), stockpile volumes (m3), create polygons, place identifying markers, identify latent machinery and add annotations using a standard browser, that can then easily be shared and commented on.

 

Drone thermal imaging cameras also present opportunities to operators to track and monitor equipment movements, inspect machinery and identify equipment that is overheating, detect groundwater inflow and even conduct search and rescue operations.

 

With dozens of potential uses and applications covering long-term and short-term planning; There are literally countless opportunities to explore the time and cost saving opportunities & benefits of UAVs.

Using one of Capital Remote Aviation Pty Ltd's  fully insured, licensed and experienced UAV operators to conduct these operations means mine sites can start to immediately realise the benefits to cut costs, deliver efficiencies and save time, without having to procure their own equipment, or submit an application for an Operator Certificate from the Civil Aviation Safety Authority (CASA).

drones can capture on-demand maps usually at lower cost than using a plane or helicopter and at a higher resolution than satellites. Unlike satellite data, drones operate on an on-demand basis and fly relatively low and so they aren’t typically affected by cloud.

Collecting imagery using satellite or manned aircraft usually requires at least a few days depending on the area covered. The production of elevation data and Orthomosaics, as well as its quality control, will often take a few weeks. With drones, it’s quite normal for a project to be flown in the morning, processed in the afternoon, and delivered by the end of the day.

After the drone has landed and the data is taken out of it, various platforms such as Propeller and Arc GIS can be used to stitch the images and process the data to deliver 3D terrain models. Outputs are geo-referenced and ortho-rectified, meaning measurements and calculations can be taken directly from them. This can be anything from a basic distance, area and slope calculations right up to stockpile volume analysis, sight-lines or watershed runoff simulations.

PropellerRed Bird and 4D Mapper also make our final models visible via your browser so our clients can easily view them without needing to download expensive software. These platforms basically allow you to manage to share your geospatial data in a browser – be it LiDAR, point-clouds, imagery, Orthomosaics, 3D terrain models (DSM/DTM), GIS data or metadata. You can even do some simple interactive functions such as overlay, digitize, measure points, lines, areas, profiles and volumes.

Resolution wise, 3cm-5cm per pixel (3-5cm GSD), is quite the norm for drone acquired data in 2017 (enough to see a small flower for example). Drones do have limitations, the cameras for instance, can’t penetrate the heavy tree cover to reveal the land below. Also, it can be tricky on a windy day if the drone is not large enough to handle wind, and there needs to be a clear space to land the drone - if it is a fixed wing machine.

SOME REASONS WHY DRONES ARE USEFUL FOR ENVIRONMENTAL EXPERTS


The terrain they can cover
Wanting to survey difficult terrain with little to no established vehicle access? Hiring a drone operator to fly across areas such as this, rather than putting people on the ground, can reduce the exposure of those people to potential hazards. For example to evaluate vegetation health along rivers or drainage channels, do inspections of elevated cave entrances or to search for rare flora along ridge lines. 

The sensors they can carry Multispectral sensors are much smaller these days, enabling a drone to carry them and map natural phenomena that could not be possible with just the human eye. 


LiDAR capability — which measures the distance from a target using a laser — can see through a forest canopy to determine the fuel density on the ground, as well as accurately plot coastal erosion.


A high-resolution camera on a drone is ideal for creating 3D photomosaic images for cultural heritage mapping and coastal erosion monitoring. Thermal and infra-red cameras, aside from detecting fires, can find wildlife in dense forests, survey solar farms hot spots, or inspect mine site machinery or wind turbines. 

They can take off from anywhere
Drones don't need a lot of aeronautical infrastructures, they launch with a catapult and land with a parachute – you don't need a runway. Manned planes need to either fly there expending a lot of fuel or can't get there at all. 

Example application 1: Planned Burns
Drones can be used to evaluate an area prior to a planned burn taking place in terms of topography, hazardous trees, nearby infrastructure, and vegetation types and densities that could lead to the crossing of containment lines. And later for monitoring the planned burns while they're taking place and post-process mapping. 


Drones also enable better communications for people on the ground, especially in remote areas, which in turn means increased safety for staff. 

Example application 2: Animal Counts
Wild pigs can get into shrubby areas, cause destruction and nest inside the scrub. They are difficult to spot during the day and from ground level. A drone with a visual or thermal camera can detect them and send a live video link to people in vehicles on the ground. 

Vertebrate pests impact both the environment and primary producers causing irreparable damage to native land, Flora and Fauna along with significant losses to the agricultural sector. Queensland based business Skies Eye Drone Services is now using thermal imaging equipment to identify animals in the darkness of night, plus the aerial advantage covers more ground cost effectively as opposed to being ground based. And the data and imagery they capture is non-invasive, keeps humans at distance and allows natural monitoring of even the most elusive native animals. 

Surveying animals such as koala population sizes at sites - drones are quieter than traditional aircraft, making the animals less likely to be disturbed and therefore easier to count. 

Example application 3: Mapping Emissions
One start-up in Finland, Aeromon, is mapping something less tangible than land: industrial emissions. It has built a drone and software platform capable of tracking invisible gases from above. 

And it’s not been easy. In order to accurately map gases as they enter the atmosphere, Aeromon team has developed a sophisticated sensor package, ‘BH-8’, which can be attached to a drone to capture data in the field. A connected analytics platform takes the information from these airborne sensors and lets plant operators and regulators map emissions in real-time. This can help governments and authorities keep factories and fossil fuel companies in check. 

Example application 4: Water Preservation
Equipped with infrared cameras, drones are being trialled in hot and remote locations, to detect leaks in underground water pipes in the desert. Research led by Professor Amin Al-Habaibeh at Nottingham Trent University in the UK aims to prevent water loss using infrared technology to spot leaks that are invisible to the naked eye. 

Example application 5: River Plain Flood Mapping
River Flood Plain Mapping can be carried out quickly, identifying developments at risk and highlighting ways to improve the problem. Both banks of a river can be mapped simultaneously and can be viewed in 3D. The software allows you to simulate different flood levels and the effect it has on the terrain. Cross sections at any point along the river can also be calculated. E.g. a simulation across shows the impact when the river level is raised 3m higher than current heights. It also highlights to flooding paths.
