The Tough Problems
Get a total set of requirements
Keep commercial processes and proprietary products involved but maintain an open exchange mechanism
Different views of the environment
- Air, land, sea, space
- Spatial location and orientation (coordinate system and datum)
Lack of underlying environmental framework
- No integrated reference model available
- Representation
- Naming/semantics
- Existing Data Models are conceptual, future models which are non-integrated and don’t address current data repositories and data interchange requirements
