5. Is LiDAR better than Photogrammetry?
Photogrammetry and LiDAR each have their strengths, which are very different, making them each the better choice for certain applications. For instance, an inspector seeking to evaluate detailed cracks in paved surfaces would likely employ photogrammetry, whereas a mining engineer aiming to calculate stockpile volumes or a land development professional creating a digital surface model would be better off using LiDAR.
LiDAR provides some key advantages in industries like surveying, construction, land development, and forestry. While photogrammetry utilizes a camera and can only collect images that can be “seen,” LiDAR is a laser scanner that actively senses the surface of the earth, even in dense canopy due to the laser finding holes in the vegation, producing more accurate models. LiDAR can also be used in any light conditions — whether it’s dark and cloudy, or even at night.
In applications where LiDAR is the best choice, using mdLiDAR solutions will allow you to complete projects much more quickly and accurately. One of the reasons for this is that LiDAR requires significantly less data than photogrammetry, so post-processing times are much faster.

6. Can LiDAR see through walls?
No. One of the key uses for LiDAR — a.k.a. Light Detection and Ranging — is mapping the surface of the earth, even in areas of dense canopy due to the LiDAR finding holes in the vegetation. The LiDAR sensor emits pulsed light waves which reflect off surrounding objects and return to the sensor. The sensor then calculates the distance the light traveled based on the time it took for each pulse to return.
By using LiDAR, the surveyor can produce a much more accurate picture of a job site, leading to better estimates and deliverables. To see drone LiDAR in action is to check out our drone surveying reality show, Down to Earth.
7. How do I get a LiDAR map?
It depends who is asking. If you are a general customer looking for LiDAR data of an area, you will want to contact an aerial surveyor who can collect the data and process it for you, creating a highly accurate surface model or point cloud.
If you are a geospatial professional who is interested in creating LiDAR deliverables for clients and who owns an mdLiDAR solution, you would simply plan your flight of the area using mdCockpit and then run the flight to collect the data. From there, you would take the SD card out of the drone, put it into your computer, and upload the data to mdInfinity, Microdrones processing software. This intuitive data processing program enables you to quickly and easily transform raw survey data into actionable insights. LiDAR requires significantly less time to process than photogrammetry, so you can complete projects faster.

10. Is LiDAR dangerous to eyes?
Microdrones mdLiDAR solutions integrate RIEGL VUX-1UAV LiDAR sensors, which fall into laser eye safety class 1. This means that the laser is safe under all conditions of normal use because the maximum permissible exposure (MPE) can’t be exceeded when viewing the laser with the naked eye. To be categorized in this safety class means that these are among the industry’s safest lasers with products adhering to the most stringent compliance measures.
Many other LiDAR applications may not fall under the same safety class as Microdrones solutions, and the safety of lasers in various circumstances involves complex determinations. Be sure to do your research on the dangers when evaluating solutions not provided by Microdrones, especially non-class 1 solutions.
