Study Notes
Reflective Surfaces and Flight Techniques
- Unique subjects like highly reflective materials (e.g., TPO roofs, bright white roofs) can pose challenges in photography.
- Adjust flight lines to position the sun off to the side to minimize glare and reflections.
- Slowing down the shutter speed can help darken overexposed images; suggested speeds are 1/800 or 1/400.
- Flying at a higher altitude reduces reflectivity and enhances image quality.
- Ideal to fly during solar noon when sunlight is directly overhead to further diminish reflections on surfaces.
- For metal panel roofs, increased altitude is particularly beneficial to capture clearer images.
Capturing Tall Buildings
- When photographing tall buildings, consider utilizing adjacent rooftops or parking structures for optimal angles.
- Ensure a minimum height of 30 feet above the Mean Oceanic Level (MOL) for accurate mapping and data capture.
- For skyscrapers, the DJI Ground Station Pro app offers a Vertical Orbit Mode flight planner, which is effective for capturing building facades.
- Maintaining visual line of sight is crucial when operating drones near taller structures to comply with regulations.
Data Management
- After data collection, organizing and uploading to platforms like Opella is essential for effective project management.
Reflective Surfaces and Flight Techniques
- Highly reflective materials, such as TPO roofs and bright white roofs, can create challenges in aerial photography due to glare.
- Adjust flight paths to angle the sun to the side, which minimizes glare and reflections on surfaces.
- Use slower shutter speeds (suggested speeds: 1/800 or 1/400) to reduce overexposure and improve image quality.
- Flying at higher altitudes can decrease surface reflectivity and enhance the clarity of images.
- Solar noon is the prime time to capture images, as sunlight is directly overhead, reducing surface reflections.
- Increased altitude is particularly advantageous for photographing metal panel roofs, leading to clearer results.
Capturing Tall Buildings
- For optimal photographs of tall buildings, consider using nearby rooftops or parking structures to gain better angles.
- Maintain a minimum altitude of 30 feet above Mean Oceanic Level (MOL) when mapping or capturing data for accuracy.
- The DJI Ground Station Pro app features a Vertical Orbit Mode, beneficial for effectively capturing building facades in skyscraper photography.
- Adhering to visual line of sight regulations is essential when operating drones near tall structures to ensure safety and compliance.
Data Management
- Post-data collection, organizing and uploading collected information to platforms like Opella is crucial for streamlined project management.
