This specification identifies the requirements to be met when raster data represented in digital, binary format are delivered to the Government. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: ATTN CALS Digital Standards Office, DISA Center for Standards, Code JIEO/JEBEB, 10701 Parkridge Blvd, Reston VA 20191-4357, by using the Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

The digital representation of raster data is classified as the following four types:

     Type 1 -     Untiled Raster Data (see 3.2).
     Type 2 -     Tiled/Untiled Raster Data.  The detail requirements for the Type 2 format
                  have been removed from this specification.  Implementation of the Type 2
                  format, also known as Office Document Architecture (ODA) Raster
                  Document Application Profile (DAP), may be accomplished in accordance
                  with the requirements of Federal Information Processing Standards (FIPS)
                  Publication 194, ODA Raster DAP.  FIPS PUB 194 is explicitly
                  incorporated into this specification by reference to define the Type 2 Raster
                  Data file format.
     Type 3 -     Tiled/Untiled Raster Data, Navy Image File Format (NIFF)
                  (see appendix A).
     Type 4 -     Tiled Raster Data, Joint Engineering Data Management Information and
                  Control System (JEDMICS) C4 (see appendix B).
