"We captured this dataset over North Point on Lizard Island in just over 90 minutes. 7,309 photos at an altitude of 12 m, 80% overlap and sidelap, covers 56K m^2. This rapid acquisition is critical when we have such a short window of low tides where the corals are exposed or nearly so."
amazing stuff!
Mind blowing coverage and resolution. | Karen Joyce
Mind blowing coverage and resolution. Not so long ago I was stoked to create an orthomosaic with 300 images. But now the drones are flying faster, and batteries lasting longer. We captured this dataset over North Point on Lizard Island in just over 90 minutes. 7,309 photos at an altitude of 12 m, 80% overlap and sidelap, covers 56K m^2. This rapid acquisition is critical when we have such a short window of low tides where the corals are exposed or nearly so. We had two drones flying (yes, with separate pilots!), each connected to the same RTK base station so the consistency between the two is excellent. I flew the north half with the DJI Matrice 4E, and Vincent Raoult flew the southern half with the DJI Mavic 3E, and importantly we communicated our flight areas and movements to avoid any risk of collision. Thx to our co-pilots Rebecca Licciardo and Tyler Hofmann! Check it out for yourself! https://lnkd.in/gUpPU7GM All data processed and available on GeoNadir.
