e-LAS has the functionality to import ground control points (GCP) and do a RMSE calculation. You can also do a tie matching of your lidar point cloud using a few selected GCPs to improve the overall accuracy.
The goal of e-LAS is to get the best out of your hardware. It is to provide a calibrated, aligned, colorized and georeferenced point cloud needed for further processing. The goal is not to have multiple additional functionalities such as classification and line work as multiples others software specialized in these categories. e-LAS has all the functionalities to get your data as accurate and precise as possible and give you the tool to validate your data with some quality control functionalities and RMSE Report.
Strip adjustment allows to reduce the point mismatch from different flight lines hereby reducing the thickness and increasing the relative precision of the overall point cloud.
Lidar surveys are conducted using multiple flight passes or scan lines to cover large areas. Strip line adjustment helps improve the overall elevation accuracy of the collected data by minimizing vertical discrepancies between adjacent strips. In cases where LiDAR data is collected over multiple dates or flights, strip line adjustment helps maintain consistency and coherence across the entire dataset. This is essential for accurate change detection analysis.
