# Point Cloud Data

## Summary

3D point cloud data is collected using the Fraunhofer 3D laserscanner. .

## Data access

Data is available via Clowder and Globus.

* **Clowder**: [scanner3DTop collection](https://terraref.ncsa.illinois.edu/clowder/collection/5728c0a4e4b03269d7079ac0)
* **Globus path**:  `/sites/ua_mac/raw_data/scanner3DTop`
* **Sensor information**: [Fraunhofer 3D scanner collection](https://terraref.ncsa.illinois.edu/clowder/files/581793394f0ce77b66562ff9?dataset=581789af4f0ce77b6655d094\&space=)

For details about using this data via Clowder or Globus, please see [Data Access](/revisions/user-manual/how-to-access-data.md) section.

## Computational pipeline

Raw sensor output (PLY) is converted to LAS format using the `ply2las` extractor

* **Description**: PLY data is converted to LAS using the 3D point cloud extractor
* **Output**: 
  * **Clowder:** LAS file is added to the dataset
