Mining & Minerals
Mining & Minerals
AAM has been providing spatial information services to the mining and minerals sectors for over 50 years. AAM pioneered the use of aerial photogrammetry for planning and route location at the birth of the iron ore mining industry in Western Australia in the 1960s.
We have stayed at the forefront of technological change, adapting each new advance in imaging and analysis for the benefit of our clients. As leaders in our field we have built comprehensive expertise in providing solutions to the challenges faced by mining and mineral companies throughout all stages of the extraction process – from exploration to rehabilitation.
Shallow Water Acoustics
Radio Controlled Unmanned Surface Vehicles (USVs) offer a method of collecting information in difficult areas such as Tailing Dams and impounded ponds.
AAM can provide the data and analysis you need to minimise the time and cost of exploration programs.
We make remote areas accessible to exploration and analysis and help with rapid assessment of wide areas to find the prime site candidates.
When you are ready to narrow in on a prospect we can assist with detailed seismic surveys and planning drilling programs through the provision of accurate and detailed multi-spectral geospatial data.
Once a site is chosen high resolution digital terrain models of the target and surrounding areas help in planning construction and development of mines and supporting infrastructure like route location and design of rail lines, pipelines, power lines and conveyors.
Airborne LiDAR can capture ground cover as well as terrain, providing baseline data and ongoing site monitoring to meet environmental reporting and management requirements.
Current computing power in combination with our dedicated fleet of aircraft fitted for aerial survey allows for quick data capture turn-around. The result is that the regular and timely monitoring of broad areas has become incredibly cost effective.
One particular open-cut mine site in Australia is imaged every month by AAM. The primary deliverable is an update of the pit model to enable mine site survey staff to calculate end of month volumes. The geospatial data we provide can also be used for monitoring earthwork contractors, pre- and post-blast volumes, ship and train loading, environmental reporting and asset management. And it can be delivered safely, accurately and efficiently within a short time frame. For our open-cut mine client we consistently deliver a three day turn-around between imaging and data provision.
"Bare earth" terrain models
The ability for airborne LiDAR to penetrate ground cover makes it possible to capture digital terrain models in environments with heavy vegetation. The terrain models are highly accurate and can be used to determine detailed drainage patterns, amongst other uses.
Contours with simultaneous imagery
By combining "Bare earth" terrain models with satellite or aerial survey imagery a realistic model of the environment incorporating accurate topographic model can be created and used for planning purposes.
Historical data - AAM Geospatial Archive
For projects that require historical multi-date imagery, foundation datasets for baseline studies, or severe time constraints, AAM has an extensive geospatial archive that may meet requirements as well as reduce time and costs. This archive includes a massive 42,600 square kilometre area covering most of the active mining and exploration region of the Pilbara in WA.
AAM partners with different satellite imagery providers in order to give our clients access to the highest quality data available for their projects. We can acquire imagery with accuracy down to 50cm and across 8 spectral bands, allowing us to perform advanced segmentation and classification of land and aquatic features. Stereo satellite images for the rapid creation of digital elevation models across large areas are also available.
We have our own fleet of aircraft fitted with high resolution multi-spectral digital cameras. Accuracy upwards of +/- 1cm (vertical height) at 1 sigma and spatial resolution starting at 5cm can be achieved. This allows for the creation of highly detailed digital terrain models. From these models our analysts can extract and quantify a broad range of data including feature categorisations and measurements of environmental details and built assets. The official term for the process is photogrammetry.
Airborne LiDAR (Light Detection And Ranging) consists of a high frequency laser scanner that records the time differential between the emission of the laser pulses and the reception of the reflected signal from the environment. By combining this data with the position and orientation of the scanner (determined by differential kinematic GPS and an Inertial Measurement Unit) LiDAR creates highly accurate and detailed models of the earth's surface with a height accuracy down to +/- 10cm.
LiDAR can pierce dense canopy, making it able to capture bare earth structure as well as its ground cover in enough detail to allow categorisation and change monitoring.
TLS uses the same technology as airborne LiDAR in a portable, ground based format. It can be used in a traditional ground survey style to capture broad site features and for the modelling of the interiors and exteriors of as-built assets like industrial plants, offshore platforms and other complicated structures. TLS can also capture individual pieces of plant equipment. This is often done to check for deformation and to monitor wear.
Our geospatial analysts are experts in extracting the most value from geospatial data for our clients. Much of our data provision powers come from careful planning and execution: combining the right imaging technologies, managing data capture for integrity and accuracy, and the selection of post-processing methodologies to give clean data.
At this stage we can supply your data in any number of custom and industry standard formats for your in-house geospatial team. Or our analysts can perform the feature analysis and categorisation your project requires, delivering GIS compliant layer data for use in your GIS system or through one of our hosted services.
Analysis and presentation
For data presentation, or further analysis, AAM offers Geocortex. Geocortex is designed for the rapid creation of web mapping and web GIS applications. The system enables enterprise-wide access to the spatial data we capture for you, in raw and presentation-ready formats. With Geocortex you can integrate the data we supply with your existing corporate data as well as with public datasets available from other services.
Enterprise-wide access to geospatial data improves overall situational awareness and the quality and rapidity of decision making.
