LiDAR vs Photogrammetry
LiDAR
Pros
-
Vegetation penetration providing accurate data even in forested or obstructed areas
​ -
Able to resolve finer details then photogrammetry (e.x. powerlines)
-
Effective in low light conditions
Cons
-
Does not capture visual mapping, point clouds have to be colorized from a seperate camera (built in on most modern LiDAR systems)
​ -
Requires specialized software and knowledge
Photogrammetry
Pros
-
Captures visual data, able to build orthomosaics or photorealistic models
-
Cheaper then LiDAR​
-
​Easier integration with standard cameras
​​​​​​​
Cons
-
Severely limited in dense vegetation or low-light conditions, as photogrammetry relies on visible light.
-
Diffecult to capture shiny, reflect, or transparent surfaces (windows, metal roofs, or water)
-
Has more distortion without proper ground control​
