Point cloud
E57
The E57 format for point cloud storage consists of two parts:
- A header, which points to an XML-encoded description of the dataset, including references to where the data is stored in the file.
- The point data, as a linear list of records. Each point has a location and various attributes.

LAS/LAZ
The LASer format is an exchange format for three-dimensional point clouds. It uses the .las extension. LASer LiDAR files also come in a compressed variant, called LASzip. In that case, they have the .laz extension.
The specifications are maintained by the ASPRS foundation. Read here (opens in a new tab) for more information about the specifications.
The LASer format is a binary format roughly consisting of three parts:
- A header, describing the number of points, the size of the point records and so on.
- Various variable-length records. These records can contain the spatial reference, but can also contain vendor-specific data.
- The point data, as a linear list of records. Each point has a location and various attributes.
LGS/LGSx
LGS files contain all project information in a single-file solution for reality capture and can be processed on HxDR. It is a format that contains rich information: not just point cloud data, but also things like the registration report, 3D model, HDR information, GeoTags, IR, metadata around projects and setups. LGSx is the upgraded LGS file format.
B2G**
B2G files are produced by sensors from Hexagon geosystems BLK family such as BLK2GO, BLK2FLY, and BLK ARC.
HTC GPR Survey
HxDR can process underground survey data acquired using ground penetrating radars(GPR) from Hexagon geosystems division.
