DGIWG Feature Data Dictionary (DFDD)
- Replacement for FACC; Supports mainly GIS/terrain features; Extensible through registration; Contains many entries and concepts from EDCS; Some digital data products based on DFDD (more is anticipated)
NSG Feature Data Dictionary (NFDD)
- The US NGA profile of DFDD (NFDD is unique to US); Uses a subset of DFDD and extends with other concepts; Contains product support constructs (including a mix of data model; not just a dictionary); Data production based on NFDD anticipated
