When Esri first introduced a Geospatial Gaussian Splat layer in ArcGIS 3.6, the story was about legitimacy. Branches, cables, chain link fences, even the negative space between leaves could finally be viewed exactly as they occur in the real world. They were registered to authoritative coordinate systems, and treated as a layer inside the ArcGIS platform.

Now, with version 5.0 of the ArcGIS Maps SDK for JavaScript, that capability moves to the web.

In February 2026, Esri formally introduced the GaussianSplatLayer in the ArcGIS Maps SDK 5.0, making splats available inside SceneView web applications. If ArcGIS 3.6 marked the desktop transition to lifelike 3D, 5.0 marks the runtime transition.

The new GaussianSplatLayer sits alongside FeatureLayer, SceneLayer, IntegratedMeshLayer, and PointCloudLayer in the SDK’s architecture. It inherits from the same Layer base class, supports portal items and service URLs, and can be added to maps and scenes without special handling. In other words, splats are not embedded as media or treated as external viewers. They are native.

A splat layer authored in ArcGIS Pro, generated through ArcGIS Reality workflows, or published as a 3D Tiles package can now be streamed directly into a web scene. Once there, it can coexist with feature layers, imagery, voxel layers, and utility network data. The layer can render in local projected scenes or in global WGS84 scenes through support for the ESRI_CRS extension.

The strength of Gaussian splatting has always been its ability to represent complexity without forcing aggressive simplification. Seeing that carried into the JavaScript SDK reinforces that this is a long term architectural decision, not a marketing experiment. The layer also uses a multi-resolution hierarchy to manage performance.

Elevation Profile, Viewshed, Line of Sight, Slice, and Volume Measurement analyses are currently not supported on Gaussian splat layers. Splats do not cast or receive shadows. Opacity adjustments are not supported in 3D SceneView. And local scenes using WGS84 (WKID 4326) are not guaranteed to always render correctly.

Gaussian splatting is increasingly treated as another spatial data type. For geospatial and AEC teams, gaussian splatting is bringing direct value to teams. It means lifelike 3D is no longer a parallel workflow. It is part of the same platform that already handles parcels, zoning envelopes, and utility networks.

With ArcGIS Maps SDK 5.0, Esri is reinforcing what began with 3.6. Radiance field representations are helping teams see more information about their work and, in turn, develop a clearer understanding of the physical world. Learn more through Esri's website.
