Tips to improve LiDAR technology for your needs

LiDAR technology is well-known for being the topmost technology for mapping purposes. Much cheaper than the traditional photogrammetric technique, LiDAR maintains to be a notch better at the quality of data it provides. The sampling of data from LiDAR is very dense, which makes the information achieved from it very detailed.

With the development in LiDAR technology, there were many tools developed which made the use of LiDAR very effective and easy. Here are a few tips that can enable us to take the best advantage of LiDAR data:

Having LiDAR in LAS Format:

LAS in short for LASer is the industry-standard format for LiDAR data. The specification is known to be maintained by ASPRS (American Society for Photogrammetry and Remote Sensing). It was originally intended for airborne LiDAR but is regularly used for terrestrial and mobile LiDAR.

LAS is a binary, efficient, and widely supported format for LiDAR. Make notes that make use of LAS format for all airborne, terrestrial and mobile LiDAR. While terrestrial LiDAR and mobile LiDAR are useful only in 3D, airborne LiDAR is useful in both 2D and 3D.

Processing of LAS File:

LAS files can be of much different nature, from taking raw LAS data to delivering it to a client the file format of LAS files goes through a lot. A few critical items in LAS processing are projections, tiling, and classifications. A project coordinate system (PCS) must contain all the files. PCS is the file needed by most clients. Files missing projection metadata are non-compliant with the specification and should be rejected or repaired.

Store Data Appropriately:

LiDAR data is very large and should be well-kept, and the wrong practice of this can lead to a long wait for users to display the data. The best approach can be determined by asking yourself questions like, how big are the data sets, and will the entire LiDAR data be processed?

If the complete data needs to go through the step of review, cleanup, and processing, it would be wise to store the data in a central server and fetch parts of the large data to process.

LiDAR data can be very complicated at times but if used wisely it is one of the best sets of data a surveyor can ever need. To best serve the increasing demands of global geospatial data drafting, acquisition, and management, Polosoft Technologies provide all kind of lidar data processing. Such as;
