How to Use the Grid Generator Point Cloud Task

1. In the Input Datasets section, a user may define a Feature Geometry Layer. This could be a polygon drawn via Tool Geometry, a shape file layer, or an uploaded File. Also, a user may define an input LAS layer. This can be the active LAS Layer, or another one. These input datasets are the data upon which the grid will be based.

2. The user can define and customize Source Points... The point filter is a set of classification, return combination, and elevation range values that define a set of points. By modifying the point filter, you can limit a set of points that can be used to create the grid surface.

3. Input the desired grid Cell Size.

4. Select the Grid Output Type.

5. The Input Geometry Clipping section is where the user can decide the extent by which the grid is created and clipped (if desired).

• Full grid (No Clipping) uses the MBR (Minimum Bounding Rectangle) of the feature geometry and/or LAS Layer to build the grid.

• Intersect Clip to Input Polygon: If used and a cell intersects with the input feature geometry and/or input LAS Layer, that cell will be written in the cell grid. If a cell does not intersect, it will not be included. The example below is using tool-drawn geometry,

• Clip to Input Polygon: Only cells which fall completely within the input geometry and/or LAS Layer will be written in the output cell grid. Those that are outside, or only partially within the geometry are not written.

6. Clip to Input LAS Data

• No Clipping: No clipping is done in relation to the input LAS Layer.

• Clip to Input LAS Data: Includes the input LAS Layer in the clipping operation. The final output will also depend on what option is selected in the Input Geometry Clipping section.

6. Grid Output Shape File is where the user defines the output file path for the cell grid shape file.
