An Integrated Model of the Environment
Environmental data is an approximation of the environment.
Note: Maps are also approximations of the real world, but requirements are different …
- Inaccuracies are accounted for through visual or cognitive interpretation
- Automated systems can’t adjust ... inconsistent representation causes errors
An integrated model must preserve real world properties that are:
- Appropriate for the specific or typical place and time
- Consistent with intuitive expectations:
- Rivers: flow downhill
- Terrain, atmosphere, ocean, and space: content agree
- Roads: connected and consistently attributed
- Cuts, fills, obstacles: appropriate to engineering practices
- Structures: attached and appropriately aligned
An integrated model must express relationships between properties, features, or phenomenon that are interdependent.
SEDRIS supports the interchange of fully integrated data.
