What kind of UAV aerial survey is better now? Do you have any recommendations?

Do we use the proud XC-25 two-headed dragon for aerial survey? People? Machine. There is nothing in this. People? The aircraft has a battery life of 6 hours, or is it the only pure electric vehicle in China that can carry 1350m ranging laser radar and reach a range of 2 hours? People? Machine. Other than that, there's nothing here. People? Many performances of the machine are first-class, absolutely ahead of the domestic level.
