After making topological corrections, it is advisable to perform additional validations to address any remaining errors. This process, while sometimes tedious and extensive, must be repeated until no errors persist. Doing so ensures the overall accuracy and reliability of the geographic data.
The correction process demonstrated with line and polygon layers reflects only one aspect of ArcGIS Pro’s topological capabilities. These corrections can be extended to a variety of layer combinations based on the needs of each project.
For instance, rules can be configured to prevent overlaps or gaps between land parcels and designated green areas. Similarly, line layers may be required to maintain internal connectivity and avoid intersections with other layers of different geometries. The flexibility of topological rules allows for tailored solutions depending on the project’s spatial characteristics.
A GIS analyst’s ability to identify and implement the appropriate topological rules is essential for solving spatial problems effectively and maintaining high data integrity.
