Esri Indexed 3D Scene Layer (I3S) Writer Parameters

Mesh Parameters

Maximum Number of Faces Per Node

This parameter directly controls the number and size of files in the scene layer package. A smaller value will result in many small files, while a higher value will result in fewer, larger files. The default value is 800.

Note  For datasets with textures, a small value is recommended. Datasets without textures can use larger values.

Point Cloud Parameters

The default is 200000.

Point Cloud Component Data Type Notes

angle

Int8

 

classification

UInt8

 

classification_flags

UInt8

Indicates special characteristics associated with each point. This is a bit flag with the following values:

  • 0 - synthetic (created by a technique other than LIDAR collection)
  • 1 - key-point (should not be removed by thinning)
  • 2 - withheld (should not be included in processing)
  • 3 - overlap (this point is in the overlap region of two or more swaths)

I3S supports storing additional components (not part of the fixed component set) for each point through an "extra bytes" Variable Length Record. The Components parameter specifies a list of components that should be written for each point.

Note that the String data type is not supported for components.

You can add, remove, or re-order the list to change the order in which the components are stored in the output dataset.
