🌟 "A Point of Interest (POI) can be as simple as a set of coordinates and an identifier, or more complex such as a three-dimensional model of a building with names in various languages, information about open and closed hours, and a civic address." - this is the abstract proposition of The Open Geospatial Consortium (OGC) on the new POI standard definition, which is available for review and comment. 📑 Definition of standards are relevant to establish common grounds for development and interoperability, where we all actors use the same words with the same meaning. In its broadest definition, a POI can be a location about which information of general interest is available. But in order to have a sound standard, more needs to be defined, like conformance with other standards already used, conventions adopted either on concepts or on notation used in the definition, different abstraction layers used for increasing levels of detail on the information to record, implementation guidelines and test cases or test methodology to adhere, and much more. 🛩 One way of collecting data for those Points of Interest is via drone flights, as we do at Digital Twins, providing complementary orthofotos and terrain models. 🔗 You can provide your contribution following this link https://lnkd.in/gVbwTbxX 🥇 All drone flights for Digital Twins are performed by a certified pilot, so we always minimize risk for people, constructions, and vehicles.

• Dead Reckoning • Dead Reckoning (DR) is a method of navigation relying on estimating one’s current track, groundspeed and position based on earlier known positions. Although DR navigation is not much used in practice today, the principles involved may still be employed by pilots to estimate, for example, their ETA for a position ahead, or to estimate an alteration of heading to regain track. Dead reckoning is the default mode in the event of failure of the input to some Flight Management System systems. This has the effect that heading and true airspeed (perhaps modified by previously encountered wind effects) are fed to the FMS in place of the track and groundspeed derived from Global Positioning System (GPS) or other navigation systems. This event, which may not be immediately evident to the pilot, results in serious degradation of navigational accuracy. Advances in navigational aids that give accurate information on position, in particular satellite navigation using the Global Positioning System, have made simple dead reckoning by humans obsolete for most purposes. However, inertial navigation systems, which provide very accurate directional information, use dead reckoning and are very widely applied. In conclusion, while possessing some shortfalls, dead reckoning remains an essential pilotage skill for navigating in conditions where electronics may malfunction or fail to be available. Its manual nature also serves as a reliable crosscheck of automated position indications. Aeronautical decision-making demands knowing when primary instruments necessitate a reversion to this backup sight navigation technique. Team ICAO online, we fly high. 🌐 www.icaoonline.com

What is the cycle time and why does it matter in aerial mapping? The cycle time or minimum frame interval is the time that it takes to take the next image. Or in other words how many images one can take within a second. On typical airborne imaging systems, the cycle time is around 0.7 sec. If we compare this with typical flying speeds for data acquisition that is something between 100 knots (185 km/h)and 180 knots (333 km/h) the distance that an aircraft travels during this 0.7 sec is between 36 m and 65 m. For an imaging flight we also need to look into the base length (distance between two image takes) that is defined by the GSD, the sensor size and the forward overlap. In general, the base length is shorter if the GSD is smaller and the forward overlap higher. To give an example, using a 14.192 by 10.640 pixel sensor and an overlap of 80%, the base length is 42 meters for a GSD of 2 cm and 106 meters for 5 cm GSD. This means that our example camera is not able to capture images with 80% forward overlap at 180 knots, but either need to fly slower or the overlap needs to be reduced. To sum up, yes the cycle time definitely matters, especially for small GSDs below 5 cm and high overlap flights. ❓ Did you ever have to adjust the flight planning due to the minimum frame interval? 💡 Comment | Like | Share 👉 Follow me for more Information on exciting topics from the world of geospatial #photogrammetry #aerialmapping #mapping

🤩 Look at that radiance field and mesh! 🤩 My initial thoughts on 2DGS for Geometrically Accurate Radiance Fields. I am still learning that not ALL scenes work well, but it LOVES drone flights. Tutorial is coming, I promise. Oh, and there isn't an actual viewer. I had to mod the pipeline to make it work. Michael Rubloff #3d #geospatial #computervision

How does RTK GPS work? 1.What is RTK GPS? RTK GPS stands for Real-Time Kinematic Global Positioning System. It is a satellite-based navigation system that provides highly accurate positioning information in real-time. Unlike conventional GPS systems, which typically offer accuracy within several meters, RTK GPS can achieve centimeter-level accuracy, making it invaluable for applications that require precise positioning data. 2.How does RTK GPS work? At the core of RTK GPS technology is a process called kinematic positioning. RTK GPS systems consist of two main components: a base station and a rover receiver. The base station, typically placed at a known location with a precisely determined position, receives signals from GPS satellites and calculates corrections for errors in the positioning data. These corrections are then transmitted to the rover receiver, which is mounted on a moving object or device. The rover receiver uses the corrections received from the base station to refine its own GPS measurements in real-time, resulting in highly accurate positioning information. The applications and benefits of RTK GPS are expected to expand further, paving the way for new possibilities in precision positioning and beyond. For example, the ER-GNSS-M02 positioning module provides robust support for multi-frequency positioning across all major satellite constellations, including Beidou, GPS, GLONASS, Galileo, QZSS, and NavIC. With its high-precision RTK algorithm engine, achieving centimeter-level positioning accuracy becomes effortless. Additionally, the module comes equipped with an integrated Inertial Measurement Unit (IMU) and employs a tight combination algorithm, ensuring seamless and continuous navigation and positioning output. Its compact size, minimal power consumption, and ease of system integration make it an ideal choice for various applications. Furthermore, the module supports long baseline RTK solutions and boasts fast initialization times, enhancing its versatility and usability.
