Source data requirements

This section describes the minimum requirements for source data to ensure efficient and reliable upload into Omnibase. The content will be updated when recurring support questions require clarification.

Technical requirements – Point clouds​

Point clouds must be uploaded in .las or .laz format.

Requirements:

  • The file must comply with the LAS specification.
  • A valid bounding box is mandatory:
    • No points may exist outside the defined bounding box.
  • The file must not be corrupt.
  • Additional attributes and classifications must follow the LAS specification as defined in the LAS standard.

Technical requirements – Panorama images​

Panorama images must be delivered as fully stitched 360-degree images, without residual lens distortion.

Accepted formats:

  • .jpg
  • .jpeg
  • .png

In addition, for each panorama location:

  • Adjusted position and orientation parameters must be provided at upload.

Linking is performed based on the filename:

  • The image filename and the filename in the external orientation file must match exactly (1:1).

Technical requirements – Aerial images​

Aerial images must be delivered without residual lens distortion.

Accepted formats:

  • .jpg
  • .jpeg
  • .tif
  • .tiff

For each image location, the following must be provided at upload:

  • Adjusted position and orientation parameters
  • Camera calibration parameters

Linking is based on filename:

  • The image filename and the filename in the external orientation file must match exactly (1:1).

Technical requirements – 3D Tiles​

3D models are supported in 3D Tiles format.

  • Full support: 3D Tiles v1.0
  • Limited support: 3D Tiles v1.1
  • Supported bounding volume: Box
  • Internal structure must comply with the 3D Tiles specification.

Currently supported:

  • Rendering of 3D models via 3D Tiles standard.
  • Not supported: point clouds stored within 3D Tiles format.

Coordinate reference systems​

3D Tiles may be stored in:

  • RD/NAP
  • WGS84 (ECEF)

Important:
When exporting from processing software:

  • If working in RD/NAP, ensure correct transformation from RD/NAP → WGS84 ECEF.
  • The correct RD and NAP correction grids must be applied.
