I3S
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:
- Go to the "Map" tab and select "Add Data"
- Choose the DWG file
- 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|
