Compressed ARC Digitized Raster Graphics (CADRG) 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.
All feature types share similar General Parameters. This includes Name and Writer Name. From here, you can also control Dynamic Properties.
These parameters apply only to a selected feature type, not to the entire writer.
Tip: If a feature type parameter listed here conflicts with a writer-level parameter, then the writer parameter will be ignored and this feature type parameter will be used.
A 4-byte ASCII character string coded to indicate the scale of the destination dataset.
Among all the format attributes, the Data Series Code (Resolution) is the most important. The data series code determines the scale, or resolution, of the destination dataset. According to MIL-STD-2411-1, there are 12 fixed scales and 6 various scales. The scales affect the resolution of the frame files in each zone. When the source raster does not have the correct spacing, the CADRG writer must resample the raster.
To avoid resampling of the raster all the time, one of the various scales can be used. In the various scale cases, CADRG writer determines the best resolution from the spacing of the raster. However, the writer may still need to resample the raster due to different spacings in different zones in the same scale. If this attribute is not set or is set to Auto (case-insensitive), data series code value MM is implied.
A 2-byte ASCII character coded to indicate the originating country or international affiliation of the security classification of the table of contents file.
A 1-byte ASCII character coded to indicate the security level of this file. For example, U = unclassified, C = confidential, S = secret.
A 2-byte ASCII character string coded to indicate any special handling or releasability restrictions assigned to the contents of the table of contents file.
A 5-byte ASCII encoded character string, identifying in human-readable form a designator for the organization that produced the frame files associated with this boundary rectangle record.
CADRG files are usually physically formatted within National Imagery Transmission Format (NITF) messages. That is, the CADRG data is embedded inside an NITF file. This parameter specifies whether the writer should embed the TOC file in an NITF file.
For greatest compatibility, this parameter should be set to Yes. However, some applications may only be compatible with output generated when the options are set to No.
A 2-byte ASCII character string coded to indicate the originating country or international affiliation of the security classification of the frame file. Same as TOC Security Country/International Code.
A 1-byte ASCII character coded to indicate the security level of this file. For example, U = unclassified, C = confidential, S = secret.

Rasters may need to be resampled to different sizes during writing. This option specifies how cell values should be interpolated:
- Nearest Neighbor is the fastest but produces the poorest image quality.
- Bilinear provides a reasonable balance of speed and quality.
- Bicubic is the slowest but produces the best image quality.
- Average 4and Average 16 have a performance similar to Bilinear and are useful for numeric rasters such as DEMs.
