It depends on the your needs. A simple guideline is something like this More penetration of vegetation = more returns = more noise on perfectly flat surfaces eg.roads Higher Hz = Higher chance of ground data = more data but can also mean more noise if used wrongly Repetitive = more accurate but less points Non-repetitive = less accurate but higher chance of hitting stuff like powerlines You can refer to this document for more details dl.djicdn.com/downloads/Zenmuse_L1/20230420/DJI_L1_Operation_Guidebook_V1.2.pdf Hope this helps!
Could you mount on top of a car and use it for like mobile mapping? Is it possible to make multiple passes to increase resolution? I guess its obviously phisiclaly possible and the data merging is mor of a software thing afterward in workstation. It would be could to test on car and also do try merbe aerial and ground level.
At the moment, the data capture only works in an autonomous flight situation. So you cannot manual capture on a car. Plus, the nature of the lidar beam will make road mapping tricky due to the FOV of the sensor. You can make multiple passes to increase "resolution" but what you will really be doing is increasing the point density. If the data is fuzzy, it can actually make what you want to see less clear. If you have a set, feel free to try! Cheers!
