FME can read and write Cloud Optimized Point Cloud (COPC) files.
About COPC and LAS
A COPC file is a geospatially organized, LASzip compressed file. This typically enables more efficient workflows in the cloud – you can organize the points spatially and then download only the points that are in a selected region.
FME supports HTTP and FTP servers and region selection with a rectangular Search Envelope.
By using COPC, organizations can efficiently manage LiDAR point cloud data, making it more accessible and facilitating applications that require streaming or on-the-fly processing of point cloud data, especially in cloud-based environments.
- For more information about COPC, see the COPC – Cloud Optimized Point Cloud website.

Reader Overview
The COPC reader inherits LiDAR Data Exchange Format (LAS) functionality, but COPC compresses LAS data and stores information in a smaller space.
To read a COPC file, enter an FTP URL, HTTP URL, or a file path in the reader dataset parameters.
If a search envelope is provided and the reader parameter Clip to Search Envelope is checked, then FME will only load the parts of the file that lie within the search envelope. This provides time savings on local and remote files.
Writer Overview
The COPC writer inherits LAS functionality, with the addition of a spatial sorting stage during the writing process.
The COPC file enables faster performance when reading a spatial subset of the dataset, as well as reading lower-resolution versions of the dataset.
