Digital Mapping Charting, and Geodesy Analysis Program Technical Review of Vector Quantization (VQ) Decompression for the National Imagery Transmission Format Standard (NlTFS).
NAVAL RESEARCH LAB STENNIS SPACE CENTER MS
Pagination or Media Count:
The Draft Military Standard Vector Quantization VQ Decompression for the National Imagery Transmission Format Standard, providing a format for images compressed via a VQ scheme, has been reviewed by the Naval Research Laboratorys Digital Mapping, Charting, and Geodesy Analysis Program DMAP at the request of the Oceanographer of the Navy. The written standard itself is practically complete DMAP provides exact details on essential modifications to the document. In addition, suggested modifications and editorial comments are supplied in an effort to enhance the document. DMAPs main issue, however, the lack of information on the relationship of this standard to the already-under-development Raster Product Format RPF, which also provides for the compressed images and is not confined to a single compression scheme. DMAP contends that once the VQ file structure is demonstrated not to conflict with the RPF, the VQ standard will provide an acceptable format, compatible with the more comprehensive RPF, for VQ compressed images.
