For the most part, terrain editing is about editing features. You edit feature classes that participate in a terrain using standard edit tools. You can add, remove, and replace data referenced by terrains. This enables you to manage your measurement data over time, which is important, considering topographic and bathymetric projects often compile information over months and even years. A terrain dataset can grow as the data becomes available.
If a survey area needs to be updated with improved measurements, the new data can be swapped in. Minor edits don't invalidate the entire dataset. Only the affected areas need to be built, thus saving time.
In ArcSDE, terrain datasets support versioning. Multiple users can access different representations of the terrain for different projects. What-if scenarios are made possible by allowing design edits that model proposed changes to be made without actually changing the original surface. If the design is realized, the edits can be posted back to the source data.
Terrains can be edited to fix problems, make improvements, and increase or decrease their extent.
Terrain dataset edits fall into three broad categories:
- Edits to the terrain dataset schema
- Edits to measurements residing in regular feature classes
- Edits to measurements residing in embedded feature classes
