How do you evaluate and compare different TLS and LiDAR equipment and vendors?

1 TLS vs LiDAR

TLS stands for terrestrial laser scanning, which is a method of capturing 3D data of objects and environments using a stationary laser scanner mounted on a tripod or a vehicle. LiDAR stands for light detection and ranging, which is a broader term that encompasses any technique that uses laser pulses to measure distances and create 3D point clouds. LiDAR can be used on different platforms, such as airborne, mobile, or handheld. Both TLS and LiDAR have their advantages and disadvantages depending on the application, accuracy, speed, range, and cost.

2 Accuracy and Resolution

One of the most important criteria to evaluate and compare different TLS and LiDAR equipment is the accuracy and resolution of the data they produce. Accuracy refers to how close the measured values are to the true values, while resolution refers to how fine the details are in the data. Generally, higher accuracy and resolution require more time, power, and memory. Therefore, you need to balance your quality requirements with your project constraints. You can check the specifications and reviews of different equipment and vendors to see how they perform in terms of accuracy and resolution.

4 Cost and Maintenance

Of course, cost and maintenance are also important factors to consider when evaluating and comparing different TLS and LiDAR equipment and vendors. Cost includes not only the initial purchase price, but also the operational and maintenance costs, such as power consumption, software licenses, calibration, repairs, and upgrades. You need to consider your budget and return on investment when choosing your equipment and vendor. You can also look for warranty, support, and service options that can reduce your risks and expenses.

5 Compatibility and Integration

Another factor to consider when evaluating and comparing different TLS and LiDAR equipment and vendors is the compatibility and integration of the data and software. Compatibility refers to how well the data formats and standards are compatible with your existing or desired software and hardware. Integration refers to how easy it is to import, export, process, analyze, and visualize the data using your software and hardware. You need to ensure that your equipment and vendor can provide you with the data and software that you can use effectively and efficiently.
