Many industries today rely heavily on accurately scanning materials for work, such as the natural terrain, weather patterns, and more. Lidar technology is often useful for such scanning efforts, and it is based on the use of lasers to measure the distance of a point. If enough lidar scanning is done via lidar services, then a 3D image of an item or piece of terrain can be formed. Lidar detection is useful for scanning topography, and this includes using such tech in foreign nations as well as domestically. Building canals or dams in Panama, for example, may require a bilingual search for lidar services or lidar technology companies. Looking up “lidar topografia” is a fine way to find lidar services in Spanish-speaking parts of the world, and searching “lidar topografia Panama” or “lidar topografia San Salvador” can bring all kinds of results. What is there to know about lidar scanning for construction and other endeavors?

Lidar and Geography

The natural world is vast, and studying it is vital for building anything from highway overpasses to bridges, sewer pipes, dams, and more. For building these items in Central and South America, searching “lidar topografia” and working with bilingual scientists in the area is quite helpful, too. This can help the locals build a dam, for example, to open up more land for farming. If the local terrain is not scanned with lidar and other imaging services, then architects and builders will struggle to build anything that will remain stable and secure in its location. Perhaps local earthquakes would damage it, or the soil is too soft or the ground is not steady. Lidar imaging, by contrast, creates a convenient 3D image, and architects and other planners can more easily decide where to place an item, or whether to put it there at all.

Lidar scanning can be complimented with photogrammetry, the process for using two or more 2D images that are translated into 3D images and models for reference. What can be built with this information in mind? For the sake of transportation and cargo delivery, bridges and overpasses are built, and knowledge of the local terrain is essential for that effort. Starting in the 1950s, the United States underwent a massive project to build many more highways to connect towns and cities across the nation. Then-president Dwight D. Eisenhower had gotten the idea from the advanced highway network he saw in wartime Germany, and thus, the American Federal-Aid Highway Act of 1956 was born.

Highway overpasses are built from concrete, and they bear a lot of weight and they themselves are quite heavy. Building them on soft or unstable ground would lead to collapse, so lidar scanning and other geography work can be done to find the safest place to build them. The same is true for bridges that span gorges or valleys, and the ground must be secure enough for the bridge to not collapse at some point. So, before any construction project is launched, lidar surveying services can and should be hired to scan the terrain and find the best and safest spot for a project. As more and more bridges, dams, and overpasses are built across the United States, builders need to find more new places to put them, and lidar detection companies are ready to help. It is likely that the lidar scanning sector will see plenty of work in the coming decades.

Lidar scanning can be done on the ground and in the air alike, such as treaded robots with lidar scanners on board. These machines rove around the area of interest, scanning everything that they need to. In other cases, drones and other airborne vehicles can pass over the area, scanning from above to form an aerial, 3D view of the terrain with great detail. This can even track the shape and location of trees and their branches, and some lidar scanning work can digitally recreate the terrain within a few millimeters of accuracy.
