DTED (Digital Terrain Elevation Data) Writer Feature Type Parameters
To access feature type parameters, click the gear icon on a feature type in the workspace to open the Feature Type Parameter Editor. To always display the editor in Workbench, you can select View > Windows > Parameter Editor.
General
All feature types share similar General parameters, which may include the Feature Type Name, Reader or Writer Name, and Geometry.
In most Writer Feature Type parameter dialogs, you can also control Dynamic Schema Definitions. Some database formats accept a Table Qualifier prefix on the output table feature type.
See Editing Writer Feature Types for more information.
File
TAB File Generation
When set to Yes, generates a TAB file along with the output dataset.
Fill Distance
This is a non-negative integer that is used to fill unassigned pixels in output DTED files before flushing them to disk.
The value is used to control how far values will be propagated by the fill algorithm. The distance is measured in pixels in the output file.
The default value at the feature type level is 1. The maximum value is 16. A value of 0 may be used to disable use of the fill algorithm entirely.
Larger values will slow processing substantially due to the nature of the fill algorithm. Pixels assigned values by the fill algorithm are assigned values based on the weighted average of the pixels within the bounding box defined by the fill distance, centered on the empty pixel. The weighting is based on inverse square of the distance from the center.
Pixels that are not assigned values by points sent to the writer or by the fill algorithm are assigned a “no data” value of -32767 as defined in the DTED standard.
