National Imagery Transmission Format (NITF) 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, including 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.

Raster

ClosedGenerate World File

World files are used to store georeferencing information for rasters. More specifically, they describe the origin, spacing, and rotation of a raster.

ClosedGenerate TAB File

Enables or disables the generation of a TAB file along with the output image.

Compression

ClosedCompression Method

This option sets the compression to use.

ClosedJPEG Compression Level

This option sets the JPEG quality when using JPEG compression.

Note: Repeatedly reading and saving files may decrease the quality for this format. In addition, Workbench may not know which format data comes from, and whether it used lossy compression. If you know that source data comes from files with lossy compression, you should also set the compression level to 0. Although this compression still does not guarantee the exact copy of the source file, the output will be very close to the original.

ClosedJPEG2000 Compress By Percentage

This parameter sets the quality of the compression.

The range of the value is from 0 (best quality, lossless compression) to 99 (worst quality).

The default value is 75.

Advanced

ClosedJPEG2000 Encoding Profile

Particular implementations of JPEG 2000 core coding may be established as profiles. This parameter specifies which encoding profile to use.

NATO and NGA (National Geospatial-Intelligence Agency) have established profiles for certain work flows:

  • NPJE (NSIF/BIIF/NITF Preferred JPEG 2000 Encoding), which is optimized for fast image browsing and panning at high resolutions. This is the default.
  • EPJE (Exploitation Preferred JPEG Encoding), which is optimized for viewing imagery at low resolution.

Profile 0, 1, and 2 are part of the JPEG 2000 standard:

  • profile0 has some restricted features, and is suitable for mobile devices. It has the greatest compatibility.
  • profile1 is only slightly limited from JPEG 2000, and suitable for commercial applications.
  • profile2 codestreams have no constraints.
