Summary (technical issues)

• ESIG 4000 terrain triangles not accessible

  • LMTDS to create Delauney triangulation from same DTED source

• ESIG 4000 generic models not accessible

  • Assess impact of not interchanging generic models (#, frequency, mission impact)
  • Possible access through SEDRIS of model grm files
    • Need to create reference from SOFATS point features to grm model name

• SOFATS DBGS to provide SEDRIS data in geodetic (lat, long)

  • Known distortions in ModSAF UTM representation of large area databases

• SOFATS DBGS to provide SEDRIS terrain geometry fully TINned with culture

  • TARGET requires terrain TIN only. Potential for LMTDS to provide
  • CTDB compiler uses road features and discards road geometry
    • Needs terrain TIN attributed with material for mobility
    • Potential holes & mobility issues if full TIN used for terrain
    • Lack of terrain correlation if SOFATS terrain grid used
  • DRLMS compiler currently uses layered culture. Compatibility with full TIN unknown.

• Feature mapping ambiguity
