# Third Party Scans

The Multiset developer portal now supports integration with third-party scanning platforms, including **Matterport**, **NavVis**, and **Leica**, to streamline the creation of high-accuracy **Visual Positioning Systems (VPS)**. Developers can utilize these industry-leading scanning tools to generate the required data for precise localization and AR experiences.

#### Input Requirements:

* **File Format**: Scans can be uploaded as **.e57** (point cloud + panoramas) or as a **Gaussian Splat** (`.ply` + `poses.json` zipped together). Both formats are accepted by the Multiset platform.
* **Panoramas**: For e57 uploads, panoramic images must be included. These are essential for capturing comprehensive environmental data.
* **Scan Density**: The density of both the scans and the accompanying images should be **high**. Increased density ensures better visual mapping and localization accuracy.

**Panoramas can be cubic or equirectangular format, based on the vendor. The system detects the pano format.**
{% endhint %}

{% hint style="info" %}
**Gaussian Splat support (new):** Multiset now accepts **Gaussian Splats** as input for VPS. The first supported pipeline is **Xgrids** — all Xgrids scanners (**PortalCam**, L2 Pro, **K1/K2**) can export Gaussian Splats in `.ply` format via Lixel CyberColor. See [Gaussian Splat](https://docs.multiset.ai/basics/third-party-scans/gaussian-splat) for details.

3. [NavVis Scans](https://docs.multiset.ai/basics/third-party-scans/navvis-scans)
4. [Xgrids Scans](https://docs.multiset.ai/basics/third-party-scans/xgrids-scans)
5. [Faro Scans](https://docs.multiset.ai/basics/third-party-scans/faro-scans)
6. [Gaussian Splat](https://docs.multiset.ai/basics/third-party-scans/gaussian-splat) — currently supported from [Xgrids (Lixel CyberColor)](https://docs.multiset.ai/basics/third-party-scans/gaussian-splat/xgrids-gaussian-splat)

#### Benefits of High-Density Scans:

* Enhanced environmental detail for improved VPS accuracy.
* Better alignment and anchoring of AR experiences in real-world environments.
* Seamless integration with Multiset’s tools for large-scale AR deployments.

By leveraging Matterport, NavVis, and Leica’s advanced capabilities, developers can create precise and persistent AR experiences.
