LiData is a point cloud data file format defined by LiDAR360. It consists of a public header block, variable length records, and point data records.

This format can be exchanged with other common point cloud data format files, including LAS, LAZ, E57, PLY, ASCII, etc.

When loading common point cloud data formats (including: LAS, LAZ, E57, PLY, ASCII, etc.) into LiDAR360, a LiData file named after the same name will be generated, and the subsequent operations are based on that LiData file.

LiData file has a version number to indicate its version. Currently, the most updated version of LiData is V2.0.

Starting from LiDAR360 V4.0, the all the LiData versions before V2.0 are supported. For LiDAR360 V3.x, the highest supported version is LiData V1.9. The differences between LiData V1.9 and V2.0 are listed as follows:
