The Grid of points tool helps to automate the creation of spot elevations and allow drastic simplification of the number of point cloud points. No new points are created, only existing points from the input data are used. 

 
Access:
  • Click Process Pix4Dsurvey process icon or,
  • on the Menu bar, click Process > Grid of points or,
  • on the Content panel, click Grid of points > Pix4Dsurvey_processes_button.png.

Processing options

Input point cloud

Defines the point clouds used for the Grid of points process:

  • All: All point clouds in the Content > Point clouds are used for processing. 
  • Only visible - default. Only visible point clouds in the Content > Point clouds and Terrain classes are used for processing.
  • Terrain: All points in the Terrain class are used for processing. Only available after the Terrain filter is processed.
  • Non-terrain: All points in the Non-terrain class are used for processing. Only available after the Terrain filter is processed.
 
Example: When Only visible option is selected, only the visible point cloud [1] and the visible terrain class [1a] are used for processing. Point clouds and terrainn classes with visibility off (Pix4Dsurvey_visibility_off.png) are not used for processing.

Pix4Dsurvey only visible point cloud

Only the visible point cloud [1] and the visible terrain class [1a] are used for processing.

Sample distance

  • Sample distance [units]: Determines the grid size:
    • 0.1 m - 100 m, 2.5 m - default.
    • 0.1 ft - 100 ft, 8 ft - default.

Results

 
Access: Results of the Grid of points process are available in the Content - Pix4Dsurvey_grid_of_points.png Grid of points panel.

Grid of points (blue points) generated only using the terrain points with a sample distance of 2.5 m.

 
Tip: Significantly fewer points are included in the results of the Grid of points process than in the input point clouds. We recommend increasing the 3D view settings > Point size in order to increase the visibility of the results.

Export

Result of the Grid of Points process can be exported in .dxf and .shp format. More in the Export article.
