What are the advantages of optical reading theodolites over ordinary theodolites? Also, mention types of optical reading theodolite?

Digital elevation models are digital representations of x, y, and z locations of points on the surface area of a terrain. These locations are acquired either from a GPS receiver, survey instruments, or aerial or satellite stereo photography depending on the spatial accuracy needed.
These digital files of x, y, and z locations are used by the algorithms in a GIS software to transform into either three-dimensional surfaces or elevation contours. It is the GIS software that makes use of this “spatial data.” The output of these algorithms are used for further analyses and calculations.
These could be; calculating cut and fill off of the land under study, 3D visualization of a terrain, watershed and viewshed analyses, and many other civil engineering, infrastructure, architectural and even video games, defense and intelligence-related applications and uses.
Hope this helps.

Theodolites with optical instruments have advantage over other layout tools. They have more precise measurements, they are unaffected by wind or other weather factors, and they can be used on both flat ground and sloped ground.
