3d satellite images4/1/2023 ![]() When you need to conduct a precise analysis, such as performing a tree count, drones are a strong choice. Since drones take images from such a close distance, they take high-resolution images that aid in creating highly precise, detailed maps. Low Earth Orbiting satellites, which have the lowest altitude and are the most often used for satellite imaging, sit between 160 to 2000 km (over 100 miles). ![]() Satellites, on the other hand, are positioned high in the earth’s atmosphere. The FAA set a max altitude of 400 feet above the ground for drone pilots, with some exceptions. ![]() However, legal limitations require drones fly at a much lower latitude. For reference, this is about 4,000 feet higher than Mount Everest, the world’s tallest mountain. While there are regulations in place that determine how high drones are allowed to fly, current records show that the highest altitude a drone can physically reach is 10km, or 33,000 feet. Precision and Quality of Imageryĭrones are flown at a much closer distance to the Earth than satellites. ![]() In this blog, we’ll discuss the advantages of drones or satellites for five specific features and how they apply to the process of photogrammetry. While the Summit Evolution photogrammetric workstation can create projects from essentially any stereo image source, not all methods for taking photos produce the same results.įor industries, such as forestry, DOTs, and agriculture that rely on photogrammetry to survey, plan, and, monitor a variety of functions, it’s important to understand what method to use based on the situation. ![]() Drones and satellites are both methods for capturing imagery that can be used to create 3D maps using photogrammetry. ![]()
