Reader Directives
The directives listed below are processed by the E57 reader.
The suffixes shown are prefixed by the current <ReaderKeyword> in a mapping file. By default, the <ReaderKeyword> for the E57 reader is E57
.
DATASET
The value for this directive is the E57 file to be read.
The default extension for ASTM E57 files is .e57

Mapping File Syntax
E57_DATASET C:\data\file.e57
Workbench Parameter
E57 File(s)
FEATURE_TYPE_NAME
The values for this directive are listed in the table below. The Feature Type Name depends on the value used.
Value | Feature Type Name | Example |
---|---|---|
FORMAT_NAME (default value) |
<geometry_type> |
point_cloud raster |
FILE_NAME | <geometry_type>_<index> |
point_cloud_0 point_cloud_1 |
SUBDATASET_NAME | <file name>_<geometry_type> |
myfile_point_cloud myfile_raster |
FILE_NAME_AND_SUBDATASET_NAME | <file name>_<geometry_type>_<index> |
myfile_point_cloud_0 myfile_point_cloud_1 |

Workbench Parameter
Feature Type Name(s)
COMPONENT_MAP
This directive maps E57 element names to FME point cloud components. Each FME component included in this list will appear in the point cloud geometry.
Values
<E57 element name, FME component name>+
Example
intensity,fmepc_intensity,colorRed,fmepc_color_r,colorGreen,fmepc_color_g,colorBlue,fmepc_color_b

Optional
Workbench Parameter

EXPOSED_ATTRS
This directive allows the selection of format attributes to be explicitly added to the reader feature type.
This is similar to exposing format attributes on a reader feature type once it has been generated; however, it is even more powerful because it enables schema-driven applications other than Workbench to access and leverage these attributes as if they were explicitly on the schema as user attributes.
The result of picking a list of attributes is a comma-separated list of attribute names and types that will be added to the schema features. Currently all reader feature types will receive the same set of additional schema attributes for a given instance of the reader.
Required/Optional
Optional
Mapping File Syntax
Not applicable.
While it is possible for FME Objects applications to invoke this directive, the required format is not documented.
This directive is intended for use in our GUI applications (for example, Workbench) only.
