360° Virtual Tour (Pano)

The Pano APIs serve navigable 360° panoramic virtual tours built from your maps. A tour is a graph of nodes. Each node is a 360° capture point with a position, orientation, a panorama image, and links to its neighbours. Use these read APIs to build a "walk-through" viewer where a user steps from node to node.

All Pano endpoints are read-only and require your authentication token. They are mounted under /v1/pano.

Pano data is generated for maps built from panoramic input: 360 video captures (Insta360) and .e57 or MatterPak scans with embedded panoramas. Maps without pano data return 404. See 360° Virtual Tour for the concepts behind these calls and how to preview a tour in the Developer Portal.

The node object

Most responses return one or more node objects with this shape:

{
    "nodeId": "000012",
    "keyframe": 12,
    "timeS": 4.5,
    "position": [1.20, 1.60, -3.40],
    "rotation": [0.0, 0.0, 0.0, 1.0],
    "rgbKey": "…/Pano/RGB/1024/000012.jpg",
    "rgbKeys": {
        "512":  "…/Pano/RGB/512/000012.jpg",
        "1024": "…/Pano/RGB/1024/000012.jpg",
        "4096": "…/Pano/RGB/4096/000012.jpg"
    },
    "maskKey": null,
    "neighbors": [ { "nodeId": "000013", "distance": 1.05 } ]
}

position: node location [x, y, z] in the map's coordinate frame.
rotation: orientation quaternion [qx, qy, qz, qw].
rgbKeys: the node's 360° panorama at each available resolution, keyed by equirect width. rgbKey is a single default tier for clients that don't select one. See Panorama images below.
maskKey: optional person-mask image key (null if none).
neighbors: the nodes you can step to from here, with the distance in metres.

Panorama images

Image fields are storage keys, not URLs. Exchange a key for a temporary download URL:

GET /v1/file?key=…/Pano/RGB/1024/000012.jpg
→ { "url": "https://…" }

Each panorama is published at several resolutions, listed in the tour header's rgbSizes (typically [512, 1024, 4096]). rgbKeys holds one key per equirect width, so a viewer can show a small image immediately and sharpen it in place. rgbKey is a single default tier (1024) if you'd rather not choose.

// Small image for neighbours the user may step to next.
const preview = node.rgbKeys["512"];

// Sharpest image for the node the user is standing in.
const widths = Object.keys(node.rgbKeys).map(Number);
const full = node.rgbKeys[String(Math.max(...widths))];

Read the largest width out of rgbKeys rather than hard-coding "4096" — the available widths can differ between tours.

Orienting a panorama

The images are equirectangular and not heading-stabilised, so a viewer must apply each node's rotation to place it in the world. These conventions are the same for every tour:

World frame: right-handed — +X right, +Y up, +Z back.
Node frame: OpenGL/ARKit convention; rotation maps node-local → world.
Equirect mapping: the centre column of the image (u = 0.5) looks along the node's local −Z. Horizontally, yaw(u) = (u − 0.5) × 360° about +Y, positive toward +X. Vertically, v = 0 is the zenith (+90°) and v = 1 the nadir (−90°).

GET /v1/pano/{id}/window: the local neighbourhood around a starting point, for stepping through a tour without loading it all. All query params are optional:

nodeId: centre on a specific node.
x, y, z: centre on the node nearest a world position (provide all three).
qx, qy, qz, qw: an optional orientation quaternion (provide all four, together with a position) to prefer nodes the user is facing.
depth: how many graph hops to include from the centre (1–4, default 2).

You cannot pass both nodeId and a position. Precedence is nodeId → position → the tour's entry node.

    "nodeCount": 9,
    "nodes": [ /* node objects within `depth` hops of the centre */ ]
}

centerDistanceM tells you how far the chosen node sits from the position you asked for, and centerAngleDeg how far its heading differs from the orientation you passed. Both appear only when you centre by position (the second only when you also send a quaternion).

Positions are returned in the base map's frame.
