Create Building Scene Layer Content (Data Management)

Summary

Creates a scene layer package (.slpk) or scene layer content (.i3sREST) from a building layer input.

• What is a scene layer?
• Use web scene layers

Usage

• To use BIM data as input, you must first add the BIM data to an active global or local scene as a building layer. The building layer, or the layer file (.lyrx) created from the building layer, can then be used as input to the tool. For more information about working with BIM data, see What is BIM data.

• Building layers whose source are feature classes in a geodatabase can be used as input. The BIM File To Geodatabase tool can be used to copy BIM features to a geodatabase. Use the Make Building Layer tool to create a building layer from the BIM features.

• Individual category or discipline layers are not supported as input to this tool. Individual category layers can be used as input to the Create 3D Object Scene Layer Content tool, but they must first be copied to a geodatabase using the Copy Features tool and added as a stand-alone multipatch feature class to the scene.

• Filters that are created on the building layer are written to the scene layer package and are consumed in clients that support reading filters.

• For more information about building scene layers, see Building scene layers.

• The output coordinate system should match the spatial reference of the web scene in which it will be displayed. If the intended display environment will be a global web scene, use the GCS WGS84 or China Geodetic Coordinate System 2000 as the output coordinate system. A vertical coordinate system for a global scene must be ellipsoidal, EGM2008 Geoid, or EGM96 Geoid.

  Consider the following when defining z-coordinates in the 3D data being processed:

  • If the output scene layer package will have x,y coordinates in GCS WGS 84, the z-coordinate system can be defined using any ellipsoidal datum or EGM96 or EGM2008 through the Output Coordinate System parameter. If the z-coordinate system is undefined, the vertical units will be meters.
  • If the output scene layer package will store x,y values in projected coordinates and the z-coordinate system is not defined, the vertical units will be the same as the x,y coordinates. For 3D features with undefined z-units that differ from the x,y units, you can use either the Adjust 3D Z tool to convert z-values to a matching linear unit or the Define Projection tool to define the correct z-datum.

• Use the Target Cloud Connection parameter to output scene layer content to an object store located in the cloud such as Amazon S3, Azure Blob storage, Alibaba OSS, or Google Cloud. This content is ready-to-serve as a scene layer and the location you choose must be registered as a user-managed data store in ArcGIS Enterprise.

• You can build a connection file (.acs) using the Create Cloud Storage Connection File tool.

• A scene layer package can be uploaded and published directly to ArcGIS Online or Portal for ArcGIS in a browser. You can also use the Share Package tool to upload and publish directly to ArcGIS Online or Portal for ArcGIS.

• The tool default for the Parcel Processing Factor environment is 80 percent.

Parameters

Dialog

Label	Explanation	Data Type
Input Dataset	The input building layer or layer file (.lyrx).	Building Layer; Layer File
Output Scene Layer Package	The output scene layer package (.slpk).	File
Output Coordinate System (Optional)	The coordinate system of the output scene layer package. It can be any projected or custom coordinate system. Supported geographic coordinate systems include WGS 1984 and China Geodetic Coordinate System 2000. WGS 1984 and EGM96 Geoid are the default horizontal and vertical coordinate systems, respectively. The coordinate system can be specified in any of the following ways: Specify the path to a .prj file. Reference a dataset with the desired coordinate system. Use an arcpy.SpatialReference object.	Spatial Reference
Geographic Transformation (Optional)	The datum transformation method that will be used when the input layer's coordinate system uses a datum that differs from the output coordinate system. All transformations are bidirectional, regardless of the direction implied by their names. For example, NAD_1927_to_WGS_1984_3 will work correctly even if the datum conversion is from WGS84 to NAD 1927. Note: The ArcGIS coordinate system data is required for vertical datum transformations between ellipsoidal and gravity-related and two gravity-related datums.	String
Texture Optimization (Optional)	Specifies the textures that will be optimized according to the target platform where the scene layer package is used. Caution: Optimizations that include KTX2 may take significant time to process. For fastest results, use the Desktop or None options. All—All texture formats will be optimized including JPEG, DXT, and KTX2 for use in desktop, web, and mobile platforms. Desktop—Windows, Linux, and Mac supported textures will be optimized including JPEG and DXT for use in ArcGIS Pro clients on Windows and ArcGIS Runtime desktop clients on Windows, Linux, and Mac. This is the default. Mobile—Android and iOS supported textures will be optimized including JPEG and KTX2 for use in ArcGIS Runtime mobile applications. None—JPEG textures will be optimized for use in desktop and web platforms.	String
Target Cloud Connection (Optional)	The target cloud connection file (.acs) where the scene layer content (.i3sREST) will be output.	Folder
