Query Dip and Strike

Summary

This tool is used to calculate dip and strike automatically or based on the point cloud selected manually. Related analysis tool and result report are also available.

Usage

Load the point cloud in the viewer. Click Geological Analysis > Query Dip and Strike, and the toolbar will show in the viewer.

In the Query Dip and Strike window, there are several buttons: Export Data, Query Dip and Strike, Automatically Query Dip and Strike, Clear data, Statistic Report,Adjust radius and Settings.

Lidar360 save Export Data:Save data in the table as CSV file.
Lidar360 save Query Dip and Strike: By clicking this button, a round selection box will show in the point cloud viewer.You can also adjust the radius of the circle. After selecting the point cloud by the round box, the Dip and Strike info will show as 3D model in the viewer. Meanwhile, a query record will add in the table below.
Lidar360 save Auto Query Dip and Strike:This tool can automatically calculate Dip and Strike, and add the record in the table below.

  • Point Cloud File:Select point cloud file in the drop-down list.
  • From Class:Select the class of point cloud to be calculated, default setting is ground point.
  • Octree Level:Create an octree for the point cloud. The higher the level, the fewer the number of point clouds contained in each octree node. The specific results of the segmentation are as follows: the larger the value is set, the finer the queried facet, otherwise the larger the facet.
  • Facets:Parameters of Facets.
    • Facets Type:Different type of Facets.
      • Max Root mean square error:The maximum root mean square of the distance between the point cloud of the cluster and the fitted plane in the segmentation.
      • Max distance@68%:The maximum distance of the top 68% of the distance between the point cloud of the cluster in the segmentation and the fitted plane.
      • Max distance@95%:The maximum distance of the top 95% of the distance between the point cloud of the cluster in the segmentation and the fitted plane.
      • Max distance@99%(by default):The maximum distance of the top 99% of the distance between the point cloud of the cluster in the segmentation and the fitted plane.
      • Max distance: The maximum distance between the point cloud of the cluster in the segmentation and the fitted plane.
    • Distance Threshold: The larger the threshold, the more points will be segmented into a facet, which means there will be more large facets.
    • Min Points Per Facet:The minimum points of a facet. The larger the value, the more the points of a facet.
Lidar360 save Clear Data:Clear data in the viewer and the table.
Lidar360 save Statistic Report:Click the button to do statistics and filter on the dip and strike. Set the interval for dip and strike statistics. The rose diagrams and corresponding statistical reports can also be generated. When filtering, you can choose different filtering types and rendering types, and filter by setting the minimum and maximum angle threshold.
