Geospatial has become omnipotent and omnipresentThe geospatial industry saw a huge boost with the rise of computing power. Modern technologies like LiDAR and photogrammetry have been widely adopted on economic platforms such as ordinary cars and remotely piloted vehicles like aerial drones and autonomous underwater vehicles. The technical breakthroughs have provided us with huge datasets collected from the field cost-effectively, frequently and in real time. These datasets are growing exponentially and modern data technologies like Big Data are being used instead of traditional data management systems. Deep learning technologies are now being used to analyse the datasets and provide reliable and timely solutions in urban planning, agriculture, infrastructure management, mining, disaster mitigation, etc. Empowering customers While many brands focus on delivering customer satisfaction, the concept of customer empowerment is sometimes overlooked. In the past, meeting customer expectations and delivering good services was sufficient. The modern consumer, however, has many more options to consider — from greater competition among brands to new technologies and channels at their disposal. To empower customers and make them confident in their choices, brands must make each experience seamless and meaningful, while listening closely to their feedback. At Roter Group of Companies, we believe in educating customers for informed decision-making. We go beyond regular sales model to a consulting model by focusing on an in-depth understanding of the customers’ requirements and assisting them in opting for the right product for the right job, even if we that product is not a part of our offerings.

Remember Lance Naik Hanamanthappa? The soldier who was buried under an avalanche in Siachen for six days before the rescue team pulled him out, alive. His miraculous survival had surprised everyone. And why not? Never before in history, had anyone been rescued alive, days after he was buried under about 25 feet of snow. But six days is a long time, and he eventually succumbed to his injuries. Now imagine a scenario where rescue teams were laden with technology that could penetrate through snow and provide the coordinates of a buried victim. These teams would have been able to locate and rescue Hanamanthappa within hours of the avalanche. He would have survived the disaster. Unfortunately, this wasn’t possible then, but can easily be done today in India… with Rescue Radar. What is Rescue Radar? As the name suggests, it’s a radar meant to rescue people. The radar uses Ultra-wideband (UWB) technology to locate live victims trapped under the debris of collapsed structures. It doesn’t matter whether the victims are moving or immobile, UWB radar’s powerful sensors can detect minor movements like shallow breathing and heartbeats. It can even help distinguish between an animal and a human being, thus making it one of the most advanced technologies used by disaster management agencies or Search and Rescue (SAR) organizations worldwide to locate people in critical situations. How does Rescue Radar work? The low-maintenance Rescue Radar case comes with two parts: A tablet and a Rescue Radar System. All that an operator is required to do is place the system at a fixed location in a disaster zone, and monitor changes on the tablet. This is how Rescue Radar works: Once the system is switched on, the radar sends Ground Penetrating Radar (GPR) signals into the subsurface to detect movement. GPR signals can penetrate snow, soil and building materials to varying depths. Its enhanced signal analysis can sense periodic motion such as breathing or heartbeats; and within seconds, the distance between the victim and the system is displayed on the tablet. A consistent life status symbol over a number of cycles (time lapses) confirms to an operator that the victim is alive, thus reducing false alarms and saving precious time and effort of the rescuers. Rescue Radar is designed for the harshest weather conditions, can operate from -400C to +500C and can detect survivors up to the depth of 30 meters. It comes in an All-in-one package, is handy and requires no additional setup. Why India need this technology? Climate change and India’s unique geo-climatic conditions make it one of the most disaster-prone countries in the world. In fact, it ranks 14th in the list of the most vulnerable countries in the world, as per the Global Climate Risk Index report 2019. According to the National Disaster Management Authority of India, nearly 12% of the country’s total land area is prone to floods, and more than 58% of the landmass is earthquake-prone. The hilly areas are vulnerable to landslides and avalanches. Moreover, out of 7,516-km long coastline, close to 5,700 km is exposed to cyclones and tsunamis. Disaster risks are further compounded by man-made calamities like building collapse, fires, mining accidents, bomb blasts etc. Given India’s population, any disaster is likely to cause loss of lives. For example, due to heavy rains in Mumbai in June last year, a building collapsed killing 14 people. In fact, as per the National Crime Records Bureau, an average of seven people die every day due to the collapse of various structures in India (data available between 2001 and 2015). Major disasters usually damage infrastructure, causing loss of life and injury as people get trapped under debris. The difference between life and death is a matter of hours in these calamities. Hence, the life-saving response needs to be quick. Who all can benefit from our technology? Rescue efforts are often coordinated efforts among various specialized SAR agencies. In India too, it is no different. Although the National Disaster Response Force (NDRF) is the specialized force for responding to all kinds of disasters, it is often supported by other agencies depending upon the nature and scale of the devastation. Some of these organizations are: • State Disaster Response Force (SDRF) – Raised by states, they are meant to quickly respond to disasters anywhere in their respective states. • State police – They are usually the first responders in any natural or man-made disasters. • Fire Services – Their role is not only restricted to firefighting but also to rescue operations during emergencies. • Indo Tibetan Border Police Force (ITBP) – It is a specialized mountain force and the first responder for natural disasters in the Himalayas. • Indian Armed Forces (Indian Army, Indian Air Force or Indian Navy) – Their role in disaster management is well-known. Their strength lies in their manpower and the ability to move quickly to any disaster-affected area. Conclusion In India, NDRF is the first agency which is using Rescue Radar to find and save buried people. But given the country’s vastness and vulnerability to disasters, it’s important that every agency dealing with SAR operations has types of equipment that can quickly detect people under debris. After all, time is the most important factor in SAR operations, and disasters can happen anytime, anywhere. Imagine if only India had Rescue Radar with it in June 2013 when Kedarnath floods occurred, how many more people could have been saved? ================

FINDAR – GPR to detect buried forensic evidenceKnow moreFINDAR – GPR to detect buried forensic evidence Case 1: Year: June 2012 Place: Oklahoma, USA Samantha Weaver, a mother of two children, goes missing. After three years of intense investigation, police zero-in on a particular property outside Shawnee, Oklahoma. They need to examine closely the backyard of this property. Oklahoma State Bureau of Investigation (OSBI) decides to use FINDAR, a Ground Penetrating Radar (GPR) system, to quickly survey the backyard and identify areas of interest. Based on the GPR results, they discover a decomposed body under plywood and three-feet of soil. Case 2: Year: Early 1968 Place: Philadelphia, Pennsylvania, US Two teenagers go missing following a walk to a corner store. 46 years later, a relative comes across a report about two unidentified bodies of teenage girls, suspected to be related and murdered at the same time in 1968, buried in Cumru Township in Philadelphia. The relative offers police DNA samples to investigate the identity of the bodies. Police had old maps roughly indicating the location of the unmarked graves but they are hesitant to use heavy machinery as that will result infurther desecration of the bodies. Police decided to use FINDAR GPR to quickly and accurately locate the graves. In October 2013, the bodies are exhumed. DNA tests confirm that the remains are of the missing teens. And with this, a four-decade long case is solved. Things common in both these cases: Crime (Murder) Investigating Agencies Undiscovered dead body FINDAR Results – Body discovered, case solved FINDAR Is a Ground Penetrating Radar (GPR) system which is aiding law enforcement agencies worldwide in quickly detecting buried forensic evidence. Its ease of use and ability to locate evidence in real-time makes it a popular choice among police forces in several parts of the USA, Canada and Europe. How does it work? All that a user is supposed to do is identify the area which needs to be examined.

Underground 3D Scanning in BhutanSurveying cavities in underground excavation projects can be difficult and dangerous. The collapse of a roof inside the main access tunnel at a hydroelectric dam construction site in Bhutan resulted in a loss of life and a significant delay in progress. Project participants could not move forward with the tunnel work until they could ascertain the size and condition of the cavity that remained above the caved-in debris blocking the chamber. This article describes how an Indian technology application company deployed a laser scanner specially designed for cavity measurement to accurately determine the volume and dimension of the inaccessible space. In 2008, the governments of Bhutan and India committed to working jointly on the development of a multi-billion-dollar hydroelectric project in Bhutan’s Punatsangchhu region, along the river of the same name. With an original completion date of 2020, the entire endeavour would generate 10,000MW of power and supply electricity to millions of homes in Bhutan and India. The two governments set up the PHPA, an autonomous body involving organisations from both countries, to work on the massive undertaking. The centerpiece of the second phase of the project (called Punatsangchhu-II or ‘PHPA-II’) would be a dam of 86 metres high and 213.5 metres wide at the top. A series of tunnels, desilting chambers, surge and pressure shafts and an underground power station would be constructed, extending several kilometres from the dam site The two governments set up the PHPA, an autonomous body involving organisations from both countries, to work on the massive undertaking.
