What is SLPK?

A Scene Layer Package (SLPK) file is an openly published file format for 3D geospatial data, designed as a package for storage or exchange that captures all resources for a "scene layer" structured according to the Indexed 3D Scene Layer (I3S) specification. The I3S/SLPK specification originates from Esri. A scene layer displays one of four data types: points, point cloud, 3D objects, or an integrated mesh.

How to create a SLPK?

In this documentation we will look on how to export a SLPK with ArcGIS Pro. To learn more about ArcGIS Pro visit ESRI's ArcGis Pro Documentation. In order to export a 3d model as a SLPK it first must be imported into ArcGIS Pro and Georeferenced if it has no world coördinates. ArcGIS Pro allows for the following file formats to be imported:

• DWG (Drawing) Used in CAD packages. Can be exported from most 3d animation packages.
• OBJ (Wavefront object) Used in most 3d animation packages like Autodesk 3dsmax and Maya.
• DAE (Collada) Used in most 3d animation packages like Autodesk 3dsmax and Maya.
• 3DS (3d studio) Used as an exported file from Autodesk 3dsmax.
• FLT (OpenFlight) Used in MultiGen Creator.
• WRL (Virtual Reality Modeling Language File)A VRML file format for representing 3D vector graphics.

There are differences in how a DWG file is added to your project from other 3d file formats. We will explain both methods below.

Adding a DWG file to ArcGIS Pro

If you are working with CAD data follow this procedure to import and convert the DWG to a SLPK file:
