Practical advice on how and why to get certified by Christa Campbell Although I have been in the GIS profession off and on, it has always been my goal to focus my career in the GIS realm. Th

    3D Volume Interpolation??

    cyberiba
    By cyberiba,
    Hello all! Well, let´s see if I explain myself: I would like to to produce a detailed salinity 3D model for a body of water. I´m currently working in a river so the water body is irregularly shaped. I have a set of points that vary across the water body.  These points vary in both their x,y locations, and in their elevation (or depth in this case).  For any given x,y location I have several depths where salinity was measured at regular intervals of 0.5 meters. I also have a bathymetry of

    How to use LPS with Quadrocopter images?

    maunaloa
    By maunaloa,
    Hi guys! My gang working with a quadrocopter, which equipped with a simple digital camera. It makes 16 mpixel images. We wanted, to test it on an archeological site, to create ortophoto and surface model. We made photos, collected geodetical point datas. We installed the LPS, and wanted to use the photos. BUT, if i want to open the images with lps, and join to the session, i need to setup some thing, for example camera info (lense and other numbers), etc. My images are "raw" images, no croshai

    Trimble Acquires Google's SketchUp 3D Modeling Platform

    Lurker
    By Lurker,
    Trimble announced that it has entered into a definitive agreement to acquire SketchUp, one of the most popular 3D modeling tools in the world, from Google. The transaction is expected to close in the second quarter of 2012, According to the announcement, as part of the SketchUp platform, Trimble will also partner with Google on running and further developing SketchUp's 3D Warehouse, an online repository where users can find, share, store and collaborate on 3D models. The site enables users to

    Terrain Navigator Pro 9.1 Released

    Lurker
    By Lurker,
    The new version of the popular mapping software provides a complete multi-year library of topographic maps and aerial photographs as well as up-to-date road and street networks. Professionals, from foresters to realtors to search-and-rescue teams and scientists, can now view multiple editions of aerial photographs, dating from 2003 to the most current, and topographical maps, including the original United States Geological Survey (USGS) topographic maps and more than 14,000 topo maps enhanced

    • Sometimes you need to create a satellite navigation tracking device that communicates via a low-power mesh network. [Powerfeatherdev] was in just that situation, and they whipped up a particularly compact solution to do the job. As you might have guessed based on the name of its creator, this build is based around the ESP32-S3 PowerFeather board. The PowerFeather has the benefit of robust power management features, which makes it perfect for a power-sipping project that’s intended to run for a long time. It can even run on solar power and manage battery levels if so desired. The GPS and LoRa gear is all mounted on a secondary “wing” PCB that slots directly on to the PowerFeather like a Arduino shield or Raspberry Pi HAT. The whole assembly is barely larger than a AA battery. It’s basically a super-small GPS tracker that transmits over LoRa, while being optimized for maximum run time on limited power from a small lithium-ion cell. If you’re needing to do some long-duration, low-power tracking task for a project, this might be right up your alley. https://hackaday.com/2024/10/17/tiny-lora-gps-node-relies-on-esp32/
    • Multiple motors or servos are the norm for drones to achieve controllable flight, but a team from MARS LAB HKU was able to a 360° lidar scanning drone with full control on just a single motor and no additional actuators. Video after the break. The key to controllable flight is the swashplateless propeller design that we’ve seen a few times, but it always required a second propeller to counteract self-rotation. In this case, the team was able to make that self-rotation work so that they could achieve 360° scanning with a single fixed LIDAR sensor. Self-rotation still needs to be slowed, so this was done with four stationary vanes. The single rotor also means better efficiency compared to a multi-rotor with similar propeller disk area. The LIDAR comprises a full 50% of the drone’s weight and provides a conical FOV out to a range of 450m. All processing happens onboard the drone, with point cloud data being processed by a LIDAR-inertial odometry framework. This allows the drone to track and plan its flight path while also building a 3D map of an unknown environment. This means it would be extremely useful for indoor or underground environments where GPS or other positioning systems are not available. All the design files and code for the drone are up on GitHub, and most of the electronic components are off-the-shelf. This means you can build your own, and the expensive lidar sensor is not required to get it flying. This seems like a great platform for further experimentation, and getting usable video from a normal camera would be an interesting challenge.   Single Rotor Drone Spins For 360 Lidar Scanning | Hackaday
    • The fall update to Global Mapper includes numerous usability updates, processing improvements, and with Pro, beta access to the Global Mapper Insight and Learning Engine which contains deep learning-based image analysis tools. Global Mapper is a complete geospatial software solution. The Standard version excels at basic vector, raster, and terrain editing, with Global Mapper Pro expanding the toolset to support drone-collected image processing, point cloud classification and extraction, and many more advanced image and terrain analysis options. Version 26.0 of Global Mapper Standard focuses on ease-of-use updates to improve the experience and efficiency of the software. A Global Search acts as a toolbox to locate any tool within the program, and a source search in the online data streaming tool makes it easier to bring online data into the application. Updates for working with 3D data include construction site planning to keep all edited terrain for a flattened site within a selected area and the ability to finely adjust the vertex position of 3D lines in reference to terrain in the Path Profile tool. Perhaps the largest addition to Global Mapper Pro v26.0 is the availability of the new Insight and Learning Engine which provides deep learning-based image analysis. Available with Global Mapper Pro for a limited time for users to test and explore, users can leverage built-in models for building extraction, vehicle detection, or land cover classification. These models can even be fine-tuned with iterative training to optimize the analysis for the data area.
