Validate Scene Layer (Data Management)

Summary

Evaluates a scene layer package (*.slpk or *.i3sREST) in a cloud store to determine its conformity to I3S specifications.

Usage

• This tool will validate scene layer content using the I3S specification to identify issues that may cause problems when viewing the scene layer in an ArcGIS client application. Consider running this tool before consuming or publishing a scene layer package generated outside of the ArcGIS platform.

• The tool will identify the presence of the following:

  • Expected values for all required and recommended JSON objects
  • Declared textures for buildings, 3D objects, and integrated meshes
  • Declared attributes and associated statistics for points, buildings, 3D objects, and point clouds
  • Declared vertex attributes such as position, color, UV, and normals
  • Root nodes and declared child nodes in the node tree

• The default output report is a readable .json file, but it can also be generated as a .txt or .xml file. The report lists warnings for issues that do not conform to the I3S specifications but may not cause a problem in displaying the data, and errors for issues that will cause problems in rendering the scene layer package.
