How to fix a geodatabase topology error in ArcGIS?
Create Feature: The Create Feature fix creates a new polygon feature out of the portion of overlap from the existing polygon so the boundary of each feature from both feature classes is the same. This fix can be applied to one or more selected Must Be Covered By Feature Class Of errors.
Which is Topology data model does ArcGIS use?
The geodatabase includes a topological data model using an open storage format for simple features (feature classes of points, lines, and polygons), topology rules, and topologically integrated coordinates among features with shared geometry.
What are the rules for validating a topology?
Any line feature, such as these lines in red, that would collapse when validating the topology is an error. Requires that lines not overlap with lines in the same feature class (or subtype). This rule is used where line segments should not be duplicated, for example, in a stream feature class. Lines can cross or intersect but cannot share segments.
What are the point rules in geodatabase topology?
Point rules. Requires that points in one feature class must be covered by the endpoints of lines in another feature class. This rule is similar to the line rule Endpoint Must Be Covered By except that, in cases where the rule is violated, it is the point feature that is marked as an error rather than the line.
How to delete feature classes from a geodatabase?
Chances are you’d never have it try to delete one that doesn’t exist but this way, it keeps deleting if it DOES find one that doesn’t exist (maybe you or someone else deleted it before it got there). I find that to be a good practice. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
How does a read lock work in geodatabase?
When working with the contents of a file geodatabase (for instance, adding a new feature class), a read lock is created. A read lock means other users are able to read the file, but are unable to edit the file. Only the first person who gets the read lock is allowed to edit the file.
