    Sunny weather in the summer will help. It will solar load the ground making it hotter. It will make the water evaporate quicker making those areas cooler.

    No. The AUVSI TOPs program is pointless. There isn't a single company that gives a crap about it. Don't waste your money.

    It's possible to find leaks with a thermal. In the summer when hot the water leaks will appear cold and in the winter vice versa. Farmers with drones do this often to find broken irrigation lines and to look for too much watering in sections.

    AVUSI has these Trusted Operator certificates that they make you pay a lot of money for. The college I work at part time thought about going that route, but didn't. APSA is the Airborne Public Safety Association and offers a course called BPERP...

    Working in Public Safety, I see TFR's as being a totally misunderstood point when flying. Whether an agency is operating under Part 107 or Part 91, TFR's are misunderstood. As part of a solid preflight check, the RPIC MUST check for TFR's in...

    Your project there highlights perfectly why you (and anyone else including the LIDAR survey op) HAVE to prove your work with checkpoints. Understand that RMSE is a mathematical estimate. It can be a very good indicator of precision. But...

    I just want to add. You stated comparing mesh to the LiDAR. Compare the point cloud from your photogrammetry to the LiDAR point cloud. You can use Cloud Compare, it's free. Shift the LiDAR data to your data. Show the engineers your RMSE (I hope...

    What was your RMS? If your RMS as an example is 2 to 3 cm, the problem isn't your data, it's the older data. 0.64m is 64 cm and is not that high quality. How many check points were used in the LiDAR data? You can 100% compare data from...

    Thank you for the detailed response. I have been on the fence due to the difference in cost. Knowing that the EVO 2 is nearing its end of life, it makes sense to invest in a tool that I will be able to use for the next several years.

    jaja6009 replied to the thread Career Changer Needing Advice.
    Its a somewhat unfair question. The Matrice is a new drone packing the newest technology, while the Autel is a dated drone that is creeping closer to End of Life. Both will do the job you need, but if you are going to offer other services the...

    jaja6009 reacted to adm_geomatics's post in the thread 4 Square mile ranch with Like Like.
    A mission of 4 sqmi (640 acres) would be close to 2.5 hours of actual flight time at 200ft AGL, so add the time it would take for multiple setups to maintain VLOS. Make sure to use real-time terrain following. Travel to and from the site, data...

    What is your friend hoping to get from this? Is this just for visualization of the property does he want absolute accuracy to include elevations for contours. Some points to think about Below 80 70 overlap (You can go lower, but with such a...
