Ground Penetrating Radar
Ground Penetrating Radar (GPR) is a non-intrusive subsurface investigation method used to map structures buried in the ground – in short, it’s a way to understand the world under your feet.
GPR is not a new technology, in fact it has been used for decades as a tried and tested method to probe the ground’s internal structure. Beginning in the 1970s as a method to understand the thickness of ice sheets and glaciers, applications of the technology have grown to include the mapping of ground structures, and non-destructive testing of non-metal structures.
Today, GPR has applications across a wide range of industries providing an even wider range of potential applications. From searching for buried utilities in the Power and Oil & Gas industries, to locating buried landmines and unexploded ordinance for Public Safety and Disaster Management, to supporting Archeological digs – the potential applications of GPR are nearly limitless.
Fugitive Emissions Detection
The Oil & Gas, Energy, Industrial, and Government sectors are all under increasing pressure and public scrutiny to reduce emissions that impact ambient air quality.
The majority of leaks or irregular releases from pressurized containment are difficult to detect. These fugitive emissions are most often small releases that provide no immediate impact to human health and the environment. However, rapidly expanding activity across a number of industries has lead to gasses like methane reaching a measurable increase on the global scale.
In response, governments have placed an increased pressure and awareness on fugitive emissions detection – and specifically the identification, quantification, and reduction of methane emissions.
Drone Based Photogrammetry
Photogrammetry refers to the process of using overlapping photographs to create a map, drawing, or 3D model of a real-world object or location.
Photogrammetry is perhaps the oldest form of visual surveying, with initial uses appearing alongside the advent of photography in the mid 19th century. Photogrammetry has evolved in tandem with technologies to both capture and analyze data, leading to its continued use and relevance as a method for developing 2D and 3D models.
Photogrammetry is best used where there is a need to capture the visual details of a site, as its key benefit is that it can be used to verify what is being seen. Photogrammetry’s visual capability provides a number of potential uses. From more traditional site survey and management applications, to its emerging use as a rapid deployment tool in disaster management and public safety – the use of photogrammetry is still evolving today.
LiDAR refers to the process of using laser light reflection to collect massive quantities of data to create a 3D representation of a real-world object or location.
Perhaps one of the most powerful modeling tools on the market, LiDAR has been in use for decades as a proven technology to record precise 3D modeling data. Technological evolution has seen usage in the commercial industry increase in recent years, as LiDAR systems have become smaller and more affordable while continuing to provide increased quality and quantities of data.
The quantity and quality of data LiDAR produce make it the best choice where there is a need to capture a large volume of data with a high amount of detail. For example, where there is a need to capture data where buildings or vegetation should be excluded since the number of pulses fired allow closer data groupings than other modeling technologies – allowing LiDAR to see around surface structures to the bare earth below.
Thermal cameras translate thermal energy (heat) into visible light – providing a wide range of possible applications.
Originally developed for military use as a night vision instrument, thermal imaging cameras have quickly migrated to other industries in a wide range of uses. Like standard digital cameras, thermal cameras produce and display a digital copy of what the lens sees. The difference is that thermal cameras use infrared radiation (or heat) to generate the image – resulting in the ability to see beyond the range of visible light and view things that were previously invisible to the naked eye.
By creating the ability to see in low or zero-light situations, peer through obscuring smoke or fog, and detect imperceptible variances in temperature thermal imaging has sparked applications in a wide range of commercial use – including Public Safety, Wildlife Management, Building and Asset Management, and Healthcare.
Confined Space Inspections
Often, onsite inspections require access to areas with restricted or limited means of entry and exit.
Regardless of the purpose for an inspection in a confined space, one constant holds true – Confined space inspections require more planning, specialized skills, equipment, as well as additional labor and time to access or dismantle the system. Depending on the nature and location of the inspection, a confined space could also pose significant risks.
First, there are the physical challenges. Gaining access, limited mobility, ease of using equipment within the space, communication, and regulating the body temperature of inspectors create an environment of constant and significant risks throughout the inspection.
While drones can also be equipped with Bathymetric sensors, GPR Magnetometry is the science of measuring the strength and direction of magnetic fields – providing a valuable tool in Archeology, Mineral Exploration, and public safety.
Originally developed in the 1800’s by Carl Friedrich Gauss to formulate his law of magnetism, the application and use of Magnetometry has grown over its decades of use to become one of the most widely used geospatial survey techniques in the world.
In delivering these types of surveys, a Magnetometer is used to measure the strength and direction of magnetism in a specific area. Measuring magnetism allows for the detection and identification of any magnetic metals or materials, and allows an operator to deliver inspections that may include Unexploded Ordinance (UXO) searches, locating buried infrastructure, archelological inspections, or any survey searching for metal objects weighing a few hundred grams or heavier underground.
Bathymetric sensors translate sound into images – allowing you to see into the depths of rivers, lakes, and oceans.
Bathymetry is the measurement of the depth of water in oceans, rivers, or lakes. Bathymetric maps look similar to topographic maps, but use lines to show the shape and elevation of underwater features as opposed to land. The data collected through Bathymetric survey techniques is used to monitor climate change; develop hydrodynamic models to predict tides, currents, and hazards; or study the habitat of benthic organisms to aid in conservation and monitoring.
While high-resolution methods have yet to be perfected for deep ocean bathymetry, its provides a high degree of accuracy where used in relatively shallow water. Traditionally, these methods rely on ship based sonar to collect and compile data for studies. However, this method has some limitations.ks – you’ll see what you need to.
