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.
Export Data：Save data in the table as CSV file.
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.
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.
- Cell Size：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.
- Convex Hull: Uses the Convex Hull as the shape of each generated structural surface.
- Concave Hull: Uses the Concave Hull as the shape of each generated structural surface.
- Facets Type：Different type of Facets.
**Merge**: Click the function button to select a polygon in the window as the target polygon. Then pick other polygons in the window, which will be merged into the target polygon. Simultaneously, the corresponding data in the table below will be deleted. Right-click to finish.
Clear Data：Clear data in the viewer and the table.
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.
**Length Measurement**: Select multiple surfaces to calculate the distance between them.
Settings：Checking or unchecking the box to decide whether to show label, axis and horizontal plane.
