Question

How does a geodatabase topology ensure data integrity and maintain the spatial relationships between features?

A. specifies a valid set of topological
values for an attribute
B. groups records in a feature class, based on an attribute field
C. validates the features of a geodatabase against a set of topology rules
D. enforces referential integrity between a feature class and a related feature class

Answer 1

A geodatabase topology ensures data integrity and maintains spatial relationships between features by validating features against topology rules.

Step-by-step explanation:

A geodatabase topology ensures data integrity and maintains the spatial relationships between features by validating the features of a geodatabase against a set of topology rules. It checks for errors such as gaps, overlaps, and other spatial inconsistencies in the data.

For example, in a road network, a topology rule could ensure that no two roads intersect each other without a proper junction. If a road segment is deleted, the topology rule will detect any resulting gaps and overlaps.

This helps maintain the accuracy and integrity of the data by enforcing spatial rules and preventing data inconsistencies.
