Rugged tablets have become crucial tools in many industries ranging from the military and government work to hospitality, healthcare, and construction. Purpose-built rugged tablets can save time and money, while driving outcomes that surpass traditional methods and usher in a new era of digitization.
Forensic mapping is being revolutionized by GNSS (Global Navigation Satellite System) RTK (Real-Time Kinematic) rugged tablets. Non-land surveying work is now possible at a higher level of accuracy, delivering scientific-grade results more quickly and easily than conventional surveying equipment can and at a smaller cost. First responders to collisions, natural disasters and crime scenes can benefit by this technology, which provides them with additional safety on site while delivering exceptional results.
Law enforcement personnel can now deploy GNSS-RTK rugged tablets with drones to obtain the necessary measurements for crime scene re-creation and deliver pinpoint accuracy that is able to meet legal requirements for evidence. The centimeter-level measurement accuracies of forensic mapping with rugged tablets is aided by the incorporation of aerial photogrammetry software, allowing multiple photos of scenes to be taken and processed to create a point cloud. The data points can then be used to reconstruct a 3D version of the scene.
Rugged tablets contain the storage, computing power, and software to quickly complete these processes, and produce survey grade accuracy for documentation that will stand up in court if required. Comparable methods relying on laser scanners can be exorbitantly expensive but using RTK-GNSS enabled rugged tablets gets the job done at a fifth of the cost.
Likewise, conventional total station equipment can take several hours to complete when relying on GPS systems alone. The same task could be completed in 20-30 minutes by combining GNSS-RTK rugged tablets with drones.
When reconstructing crashes close to major roads or in rugged terrain, drone/tablet pairing allows data to be obtained swiftly so the scene can be cleared and traffic congestion relieved. Many states can qualify for grants for this equipment as it can improve incident management and first responder safety. Secondary crashes occur in one out of five accidents and are responsible for the deaths of hundreds of civilians, law enforcement officers, EMTs and rescue personnel. Clearing highway crash sites swiftly reduces the risk of such fatalities.
Conducting forensic mapping with GNSS-RTK rugged tablets and drones can improve not only the accuracy of data collected at non-land survey sites, but can mitigate negative downstream effects as well.
