The 2017 edition of The Submarine Cable Map by TeleGeography is out and it looks great!
Every year TeleGeography, a telecom data research firm, releases a stunning map related to global communications. Each and every of them is a piece of art. The 2015 edition was styled like old maps from the Age of Discovery. Last year it had a modern design and looked like an infographic.
The 2017 edition has a new theme. The map is designed in the Indiana Jones style with a collection of artifacts, journal entries, and hand-drawn sketches and it looks great! What I love about TeleGeography mapping projects is that the top-notch design is not the purpose on its own. The aim on the map is to visualize information, not the other way around, and these guys really get it!
2017 Submarine Cable Map shows a lot of interesting data. It visualizes 293 active and planned submarine telecommunication cables that are connecting the world under the ocean, changes to submarine cable capacity on major global routes in the last 20 years, aerial “photos” of major submarine cable landing stations as well as countries with the largest number of submarine cable connections, giving them higher resiliency.
The map is really stunning and it is great to know that there are still serious organizations that believe that making maps is an art. Thanks for that TeleGeography!
How badly can a drone falling on your head hurt you?
In November 2016, GoPro recalled approximately 2,500 units of its first-ever Karma drone. The company had discovered that some units were losing power during operation, and dropping out of the sky like hard rocks. Ouch!
While being hit by a drone isn’t a scenario desired by any of us, a new research released by the Federal Aviation Administration (FAA) finds that drones are relatively safer to operate around people than what was assumed earlier.
The research concludes that a UAV falling on a person’s head will cause less damage than a piece of metal or wood debris of the same mass. For example, if a DJI Phantom 3 drone weighing 1280 gm falls on your head, you have a 0.03% chance or less of getting a head injury. In contrast, if a block of steel or wood of the same weight fell on you, your risk of head injury goes up to 99%.
The research – which was conducted by a consortium of leading universities through the Alliance for System Safety of UAS through Research Excellence (ASSURE) – studied three leading types of injuries that can be associated with small drones: blunt force trauma, lacerations and penetration injuries.
Through a series of crash tests, dynamic modeling, and kinetic energy release analysis, the researchers came to a conclusion that the impact caused by a falling multi-rotor drone is lessened by aerodynamic drag. This ensures that the fall would be unhurried, when compared to wood or metal. The amount of energy a drone imparts, and the subsequent damage it causes, will also be less, because unlike wood or metal, a UAV will deform and flex more during the fall.
Meanwhile, the study recommends that blade guards be used to protect people from lacerations, and unique safety standard be developed for the lithium batteries that fuel many small drones.
The research is being welcomed by drone manufacturers and operators alike, with DJI Vice President of Policy and Legal Affairs Brendan Schulman commenting: “ASSURE’s work provides a deeper scientific understanding of the kinetic and aerodynamic factors which make drones far safer than some had thought. We look forward to more detailed research that will ensure drone safety requirements and regulations are based on measurable risk, not on fear, misunderstandings or outdated standards.”
A second phase of the study, which will examine the risks of drone collisions with aircraft, will begin in June 2017.
