MIL-DTL-89045A, DETAIL SPECIFICATION: GEOSPATIAL SYMBOLS FOR DIGITAL DISPLAYS (GeoSym) (15 FEB 2007)

MIL-DTL-89045A, DETAIL SPECIFICATION: GEOSPATIAL SYMBOLS FOR DIGITAL DISPLAYS (GeoSym) (15 FEB 2007)., This detail specification defines the content and format for the National Geospatial-Intelligence Agency (NGA) Geospatial Symbols for Digital Displays (GeoSym). Although the GeoSym development was undertaken specifically to support the display of Vector Product Format (VPF) data encoded with the Feature and Attribute Coding Catalogue (FACC), the graphic files and symbol assignment files which make up GeoSym may be used with data which is not encoded in FACC if a mapping from the native encoding scheme to the FACC equivalent can be made.
