Orbit Point Cloud

An Orbit Point Cloud (*.opc) is Orbit's native point cloud storage format.
The OPC is been developed for encoding and fast viewing and using in Orbit's 2D and 3D environment.

The Orbit processes raw point cloud file(s) into a multiresolution Orbit Point Cloud (*.opc).
This very powerful and unique technology makes it possible to view and use unlimited point cloud files at once without loading :
Navigate in 3D View

If the multi-resolution point cloud (new since version 10.4 is not yet processed for an available Orbit Run, one can update the Orbit point cloud :
Procedures > Administration > Mobile Mapping > Edit Run > Point Cloud > Update.

Importing a point cloud dataset is a one time process and will take some time. Processing time is affected by :

1. Storage format of original data.
2. Computing power, 64bit is recommended.
3. Orbit installation (64bit or 32bit) and memory configuration.
4. Speed of Access to source data and target location.

Example import of 292.258 million point cloud points using Orbit 10.5.1, 64Bit, 4GB Memory, read and write on SSD

• Las - 5.44 GB : 8m 31s (reading) + 4m 42s (writing)
• Laz - 675 MB : 39m 46s (reading) + 4m 42s (writing)
  Reading Laz = 4.67x Reading Las. It is all about compression and decompression.

The import procedure displays the progress bar of the current import phase (Reading, Writing or Writing Multi-resolution). The time required for each phase depends the above listed topics. You may wish to do this overnight for very large point cloud datasets or using the Task Manager.
