Points on Grid

This command creates a regular sampled point cloud thanks to another point cloud and a grid.

1. Optionally, select the points you want to work with using the fencing tool : all Clean / Separate selection tools are available. Use to Restore the initial cloud.

2. Define the Grid parameters:

   1. Define the Grid orientation (always in an horizontal plane)

   2. Enter the Grid step
      

   3. You can also Define a grid point i.e. a point where an intersection of the grid is supposed to be.

3. Choose the point Picking method. You have the following choices:
   

   1. Ground point: it will create points laying onto the ground of your point cloud

   2. Highest point: it will create points corresponding to the highest area of your point cloud (in the direction perpendicular to the grid)

   3. Lowest point: it will create points corresponding to the lowest area of you point cloud points (in the direction perpendicular to the grid)

4. Check Snap points to grid intersection to extract points at the exact X and Y coordinates of the grid.

5. Define the Extraction radius around each intersection.

6. Once a Preview has been computed:

   1. Define the COGO points parameters (used for Export and Send To):

      1. Feature code (use to open Virtual Surveyor Settings)

      2. First Point index

      3. Coordinates texts to write

   2. Define the texts height.

   3. Choose either to export the result in a DXF or directly send the result to another application (refer to Send to).
