Duplicate and Delete

Duplicate and delete are powerful operations because they change the working dataset quickly. They are most useful when the user already understands the surrounding geometry and attribute expectations.

Duplicate a feature

Duplicate feature workflow in a real map editing context

Use duplication when a new feature should inherit most of the attributes of a nearby feature.

1. Open Edit Layer and choose the editable layer.
2. Choose Duplicate Feature.
3. Select the source feature on the map.
4. Adjust the copied geometry if the new feature should move or extend, such as when you are creating a nearby street segment that shares most of the same attributes as the source feature.
5. Change only the attributes that should differ from the source feature.
6. Save the duplicated feature.

Delete a feature

Delete feature confirmation step

Delete only after confirming the feature is genuinely wrong or obsolete in the working version.

1. Open Edit Layer and choose the editable layer.
2. Choose Delete Feature.
3. Select the feature to remove.
4. Review the deletion prompt carefully.
5. Confirm the delete only after verifying that the feature should not remain in the active version.

Deletion is where version-aware editing matters most. If there is any doubt, create or switch to the right working version before removing the feature.
