Why try to get a 3d laser scanner(LİDAR) from a 2d laser scanner?

Hi, I want to know why try to get a 3D laser scanner from a 2d laser scanner by adding a rotation axis ? Is it only because of the high cost of 3d laser scanners ? or are there other reasons? if so what? Thanks in advance

Higher resolution? Larger range? Better coping with reflective / difficult surfaces?

But are the resolutions and range of the 2d laser scanners not constant? Do they change when they are 3d?

You implied that you are comparing 2d scanners to 3d ones. Depending on the specific specs of the 3d laser scanner, adding a rotation axis to a 2d laser scanner could result in one with a higher resolution. That is all I meant to say.

Cost could be a factor also, yes.

And you have to remember that 3D laser scanners are a relatively new thing. So home-grown / custom approaches were not uncommon when someone wanted/needed the additional dimension.
