In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes described in this section.
Bathymetric Attributed Grid features specify a matrix of x, y, and z coordinates. For each raster, there will only be a single feature returned.

| bag_type | This will always be bag_raster. |

bag_metadata_string |
XML metadata, conforming to the ISO 19115 metadata structure. Consult documentation from the Open Navigation Surface Project (http://www.opennavsurf.org/) for more information on the exact contents of the BAG metadata. Specific metadata items of interest may be extracted from this string or added to it by using the XQueryFactory. The BAG writer will preserve most of this string when writing the output metadata. However, note that the coordinate system and geometry-related information (e.g. the number of rows/columns, the bounding box, etc.) will be determined from the feature, rather than taken from this attribute. Also note that the schema of this metadata changed in version 1.5.0. Metadata read from older BAG files is not compatible, and will not be preserved. |
| bag_version |
The version of the BAG file. The writer will produce files of version 1.5.0. |
| bag_tracking_list{}.row | Row of the modified node. |
| bag_tracking_list{}.col | Column of the modified node. |
| bag_tracking_list{}.depth | Original depth value before the change was applied. |
| bag_tracking_list{}.uncertainty | Original uncertainty value before the change was applied. |
| bag_tracking_list{}.track_code | Reason code indicating why the modification was made. |
| bag_tracking_list{}.tracking_id |
Index number indicating the process step in the metadata that describes the modifications. |
