## Strip Alignment ##

This tutorial introduces the standard workflow of strip alignment for airborne LiDAR point clouds through boresight calibration by LiDAR360.   

### Steps ###

1. **Data Quality Inspection**
    Data Quality Inspection is required to make sure the data meets the requirements of strip alignment module. It improves the alignment quality after processing. 
    - 1.1. Click ***Strip Alignment > [Trajectory Quality Analysis](../ToolReference/StripAlignment/TrajectoryQualityAnalysis.md)*** to check the trajectory quality from the height analysis, speed analysis and flight attitude analysis.
    - 1.2. Click ***Strip Alignment > [Strip Overlap Analysis](../ToolReference/StripAlignment/StripOverlapAnalysis.md)*** to analyze the overlap between point clouds.
    - 1.3. Click ***Strip Alignment > [Density Quality Analysis](../ToolReference/StripAlignment/DensityQualityAnalysis.md)*** to analyze the density of point cloud.

2. Click ***Strip Alignment > [Boresight](../ToolReference/StripAlignment/StripAlignment.md)*** to align strips through boresight calibration.

3. **(Optional)** Click ***Strip Alignment > [Elevation Difference Inspection](../ToolReference/StripAlignment/ElevationDifferenceInspection.md)*** to analyze the elevation difference between point clouds.

4. **(Optional)** Click <img src="../Icon/Trajectory/ClassifyBylowPoint.svg" alt="Overllapped" height="20" style="vertical-align:middle"/> [**Cut Overlap**](../ToolReference/StripAlignment/StripAlignment.md#12) in the [**Strip Alignment**](../ToolReference/StripAlignment/StripAlignment.md) module. For point cloud from LiDAR, the smaller the scanning angle, the higher the quality of the corresponding point cloud. Therefore, to ensure the quality of the point cloud data in the area, the low quality redundant points in the overlapped regions can be removed.
