ASTM E57 Reader/Writer

Licensing options for this format begin with FME Professional Edition.

The ASTM E57 Reader/Writer allows FME to access data in the E57 format.

Overview

The E57 file format is a compact, vendor-neutral format for storing point clouds, images, and metadata produced by 3D imaging systems, such as laser scanners.

A single E57 file may contain any number of point clouds and rasters.

E57 files are structured as a tree. A path is a string that specifies the sequence of element names when traversing the tree.

Point cloud data is read from path /data3D. Raster data is read from path /images2D.

An E57 file may contain attributes and geometry traits. Elements at the root of the tree are treated as attributes, e.g. /guid. Elements within a geometry node will be treated as geometry traits, e.g. /data3D/0/points/guid.

Note: All features will share the same attributes, but traits will differ per feature.
