With its high resolution and accuracy, aerial imaging and LiDAR scanning (ALS) can be used in the creation of high-quality topographic products. Simoultaneous ALS is ideal for continuous mapping of long corridors for highways, railways, powerlines, pipelines and other major infrastructure projects. Also, by using this technology one can have digital terrain models (DTM) and 3D point clouds that cannot always be achieved using traditional surveying techniques or photogrammetry. This is especially true when it comes to rural, unapproachable terrain, covered mainly with vegetation where probability for the lack of GNSS signal is pretty high.

Having in mind time needed for data acquisition and processing, costs and timeframes for data delivery, we believe that in this moment there is no better technology to have high quality topographic data, with reasonable price, in short time period.

It is therefore no surprise that aerial/LiDAR technology is very often used in the designing of new and reconstruction of existing highways. Traditionally, railway track measurement was performed by regular survey system. Now, with aerial/LiDAR system very precise measurements can be done in a fraction of the time. That is why, this technology represents fast, accurate and cost-effective solution to map complete railway networks.
