LiDAR is the technology which is helping civil engineering and survey agencies like never before. LiDAR uses light detection and ranging phenomenon which is quite similar to the much-spoken RADAR technology.
The biggest difference between the two technologies is that LiDAR is much more accurate and easy to apply technology.
Processing topographical LiDAR data needs 2 major steps a) an interior quality check of the information and b) an external quality check. Quality checking primarily means that ensuring 3 points:
the data density (to guarantee appropriate DTM output) and also the horizontal and vertical accuracy of data. data density might not be complied with once the survey navigation isn't properly allotted, leading to gaps between adjacent swaths or over water patches (since water theoretically absorbs the infra-red radiation). The operators sometimes offer a density map in conjunction with the data files. internal control for topographical information involves obtaining obviate outliers which can be a result of some obstructions to the sunshine path. It additionally means that filtering objects of no direct interest for the user (typically vegetation, homes and any human objects) to make a DTM representing true ground heights. whereas the bottom signature is retrieved fairly simply on the topographical measuring instrument, rock bottom signature is far additional advanced to notice on oceanography measuring instrument. I observe all teams of dots area unit separately reviewed by the interpreter UN agency decides whether or not rock bottom has been found or not. This additionally depends on the context (neighboring dots) and examination of the waveforms. lightweight break up could also be modulated by standing vegetation (e.g. ocean grass or kelp) which may jeopardize bottom detection.
