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 a DWG file:

How to import a DWG file into ArcGis:
  1. Go to the "Map" tab and select "Add Data"
  2. Choose the DWG file
  3. Select Multipatch

Importing other 3d files

To import other 3d files like OBJ, DAE, 3DS, FLT or WRL follow this procedure:

{{editor steps|title=import 3d files|Go to the "Analysis" Tab and select "Tools".|On the right pane select the "Import 3D Files" tool or type it in the search bar to find it.|In the "Input files" field click on the folder icon next to the field and browse to the 3d file you want to import|
